Best Noise-Cancelling Headphones Under $400 (2026)
What are the best noise-cancelling headphones under $400 in 2026?
TL;DR
Top pick: Bose QuietComfort Ultra 2nd Gen (~$370) — ~87% measured ANC plus the plushest comfort, and now the only established flagship still under $400.
Best value: Sony WH-1000XM5 (~$248) — flagship-tier ANC + LDAC at 38% off MSRP.
Best budget: Sennheiser ACCENTUM Plus (~$130) — 50h battery and aptX Adaptive for a third of flagship money.
New this cycle: Sennheiser Momentum 5 (~$399.95) squeaks under the cap with a user-replaceable battery. Sony WH-1000XM6 (~$458) and B&W Px7 S3 (~$469) have both risen above the $400 cap — buy on sale only. [src1, src2, src3, src11, src12]
Summary
The deep June summer sale that defined this bracket has fully unwound. As of July 29 2026 every model here is 10–25% more expensive than it was five weeks ago, and — critically — two flagships have crossed above the $400 cap. The Sony WH-1000XM6, this card's previous top pick at ~$378, has rebounded to ~$458 (essentially its $459 MSRP), and the Bowers & Wilkins Px7 S3 sits at ~$469. Both remain the strongest performers on paper — RTINGS still rates the XM6 the best noise-cancelling headphone it has tested — but neither can be recommended as an "under $400" purchase at today's prices. [src1, src3, src9, src10]
That makes the Bose QuietComfort Ultra (2nd Gen) at ~$370 the new top pick: it is the only established flagship still inside the cap, and SoundGuys' most recent measurement puts it at ~87% ambient-noise attenuation — statistically level with the Sony XM6 rather than the 2-point deficit earlier tests suggested. It pairs that with the best passive isolation and plushest cushions in the segment, 30h battery, aptX Adaptive and Cinema Mode. [src5, src8, src9, src11]
The other headline is a genuinely new model. Sennheiser launched the Momentum 5 Wireless in June 2026 at $399.95 — right at the ceiling. It measures ~86% attenuation (within a point of Sony and Bose), runs 57 hours with ANC on, adds Dolby Atmos optimisation and 42mm drivers, and is the first flagship in this class with a user-replaceable battery (a 700mAh cell behind four Phillips screws), which changes the ownership maths on a category that normally becomes e-waste when the cell dies. It does not replace the Momentum 4, which Sennheiser still sells alongside it at ~$220. [src11, src12]
Below the flagships, the rebound is just as broad: Sony WH-1000XM5 ~$248 (from $198), Sennheiser Momentum 4 ~$220 (from $180), Nothing Headphone (1) ~$249, Marshall Monitor III ANC ~$250, and Sennheiser ACCENTUM Plus ~$130. The biggest single swing is the Bose QuietComfort, which snapped back from a ~$179 sale low to ~$359 list — at that price it is poor value next to the QC Ultra 2nd Gen only ~$10 dearer, and is no longer the budget-comfort pick. The JBL Tour One M3 listing is In Stock but returned no Amazon buy-box price this run; treat its ~$250 figure as last-confirmed and verify live. [src2, src3, src4, src6]

Best for Each Use Case
Best Overall (under the cap): Bose QuietComfort Ultra 2nd Gen (~$370) — Check price
With the Sony XM6 back above $400, the QC Ultra 2nd Gen is the strongest headphone you can still buy inside this card's budget. SoundGuys' most recent measurement puts it at ~87% ambient-noise attenuation — level with the XM6 — and it pairs that with the best passive isolation and plushest ear cushions in the segment. The 2nd Gen adds 30h battery (up from 24h on Gen 1), aptX Adaptive for Android, Bluetooth 5.4, and a Cinema Mode for spatial audio; CustomTune ear profiling calibrates the sound on first wear. Sound is the most consistent out of the box of any model here, though EQ control is limited to 3 bands. Amazon street is ~$370 as of July 2026, down from a $449 MSRP. [src2, src3, src5, src8, src9, src11]
Best New Flagship / Most Repairable: Sennheiser Momentum 5 Wireless (~$399.95) — Check price
Launched June 2026 at $399.95, the Momentum 5 lands exactly at this card's ceiling and is the most interesting new product in the segment. It measures ~86% attenuation — within a point of Sony and Bose — and runs 57 hours with ANC on, roughly double either flagship. The headline feature is a user-replaceable 700mAh battery behind four Phillips screws, the first in this class; it turns a category that normally becomes e-waste at the three-year mark into something serviceable. 42mm drivers, Dolby Atmos optimisation, Bluetooth 5.4 ("6.0 ready"), Snapdragon Sound certification with aptX Adaptive, an 8-band EQ in Smart Control Plus, GPS-triggered profile switching, and a battery-protection mode that caps charging at 80%. At 290g it is not the lightest, but clamping force is well judged. Buy it if longevity and battery matter more than the last 1% of ANC. [src11, src12]
Best ANC — but now over the cap: Sony WH-1000XM6 (~$458) — Check price
Still the best-measuring noise canceller in the category and RTINGS' overall winner: the HD NC Processor QN3 is 7x faster than the XM5's QN1 and processes 12 microphones in real time for 87% measured ambient-noise reduction. What Hi-Fi? calls it "the most detailed, dynamic, precise and open sound heard from a wireless Sony flagship," and Tom's Guide picked it over the Bose QC Ultra 2 after a six-month head-to-head. Real-world battery is 37h 14min with ANC; the asymmetrical headband spreads weight evenly and it folds compactly. The catch is price: the June sale that put it at ~$378 has ended and it is back to ~$458, roughly 15% above this card's $400 cap. It is still the pick if you can stretch — but at today's price it is not an "under $400" purchase, and the Bose QC Ultra 2 gets you level ANC for ~$88 less. Set a price alert; it has been under $400 twice this year. [src1, src3, src5, src8, src9]
Best Sound — over the cap: Bowers & Wilkins Px7 S3 (~$469) — Check price
Tom's Guide calls it the best for "premium audio quality with incredible, well-rounded sound" and What Hi-Fi? gave it a full 5-star review for "stunning sound." Bluetooth 5.3 with aptX Adaptive and LDAC. ANC measured at 83–84% reduction by SoundGuys — slightly behind Sony/Bose but well within the top tier and "less intrusive" in tone. 30h battery, lightest of the flagships at 236g, and B&W's signature warm, refined tuning. MSRP is $449 and Amazon street is ~$469 as of July 2026 — above the $400 ceiling, as it has been all year. Recommend only if it returns to a sub-$400 sale; the previous $399 window has not come back. [src3, src4, src7]
Best Value Flagship: Sony WH-1000XM5 (~$248) — Check price
The XM5 has come off its ~$198 June low back to ~$248 — still a 38% discount from its $399 MSRP and comfortably the best price-to-performance flagship in the bracket. Dual-processor ANC with 8 microphones, LDAC hi-res audio, 30h battery, and ultralight 250g. Its 30mm drivers deliver the balanced, refined sound Sony has tuned across five generations, and DSEE Extreme upscales compressed audio. The XM5 set the benchmark every competitor measured against for three years and remains a top-3 pick across all major reviewers in 2026. At $248 versus $458 for the XM6, it is the clear-eyed choice for almost everyone. [src1, src2, src4]
Best Battery Under $250: Sennheiser Momentum 4 (~$220) — Check price
SoundGuys measured 56h 21min with ANC on — more than double Sony XM6 (37h) and Bose QC Ultra (28h). Supports aptX Adaptive for high-bitrate streaming on Android. Sound quality is consistently praised as ahead of the pack at this price, and Smart Pause auto-detects when you remove the headphones. The Amazon price has risen from its ~$180 June low to ~$220, so it is no longer the outright cheapest flagship, but it still delivers the Momentum 5's battery stamina for nearly half the money — minus the replaceable cell, Dolby Atmos and the newer ANC array. Sennheiser sells both generations concurrently; check the model number before buying. [src2, src5, src11]
Best Features: JBL Tour One M3 (~$250) — Check price
The standout feature is the SMART Tx — a remote/transmitter that lets you control the headphones AND act as a Bluetooth transmitter for sources without Bluetooth (airplane entertainment, gym equipment). Eight microphones power 3-stage adaptive ANC. JBL's specs page now claims 70h with ANC on (revised up from 35h via 2026 firmware optimization) and 70h ANC off. LDAC, LC3 codec support, JBL Spatial 360 with head tracking. SoundGuys calls its ANC "a credible competitor to the AirPods Max, Bose QC Ultra, and Sony XM6." The listing is In Stock but returned no Amazon buy-box price on this run — the ~$250 figure is last-confirmed from June 2026, so verify the live price before recommending. [src2, src6]
Best for Travel: Marshall Monitor III ANC (~$250) — Check price
Tom's Guide names it "Best Battery Life" for the entire ANC category at 70h ANC on / 100h ANC off — the longest-lasting in the bracket. Foldable hard case, premium build, Marshall's signature aesthetic. Now ~$250 on Amazon in July 2026, up from a ~$230 summer-sale low but still 34% off the $379.99 MSRP. LC3 codec support and Soundstage spatial audio. The pick for long-haul flights and multi-week trips where you can't reliably charge. [src2, src3]
Comfort, but Poor Value at List: Bose QuietComfort (~$359) — Check price
Reviewers consistently find its noise cancellation "basically as good as headphones costing $100–200 more," and at 240g with Bose's signature plush earcups it is engineered for all-day wear. The simplified feature set (no spatial audio, no aptX) normally keeps the price low. But it has snapped back from a ~$179 June sale price to ~$359 list, which puts it within ~$10 of the QuietComfort Ultra 2nd Gen — a strictly better headphone with 30h battery, aptX Adaptive, Cinema Mode and stronger ANC. At list price, skip it and buy the Ultra; at $200 or below on a sale it returns to being the best comfort-per-dollar pick in the bracket. [src3]
Best Design: Nothing Headphone (1) (~$249) — Check price
KEF-tuned acoustics — Nothing partnered with the British speaker company for the audio profile. 80h battery with ANC off (35h with ANC on). Physical roller and paddle controls replace touch surfaces for reliable tactile feedback. LDAC support, 8-band EQ via the Nothing X app, and the transparent industrial design that defines Nothing's product line. IP52 rating is rare for over-ear ANC headphones. Amazon price is ~$249 in July 2026 (up from a ~$214 June low, against a $299 list), which puts it head-to-head with the Sony XM5 — pick it for the industrial design and tactile controls rather than on price alone. [src2]
Best Budget + Lightest: Sennheiser ACCENTUM Plus (~$130) — Check price
At 227g it's the lightest ANC headphone in this roundup, with 50 hours of battery with ANC on and aptX Adaptive codec support; Sennheiser's adaptive ANC adjusts to your environment. Now ~$130 on Amazon (4.3 stars across ~1,100 ratings) — up from a ~$117 June low but still by far the cheapest pick here, at roughly a third of flagship money. ANC is adequate rather than class-leading, which is the right trade for office and commute use. A strong pick for all-day work where weight matters more than absolute ANC depth, or as a backup pair. [src2]
Head-to-Head Comparisons
Sennheiser Momentum 5 vs Bose QuietComfort Ultra (2nd Gen)
The only two flagships still inside the $400 cap, and SoundGuys calls it "a closer match than you’d think": ~86% attenuation (Momentum 5) vs ~87% (Bose), the same Bluetooth 5.4 and aptX Adaptive codec set, and near-identical sound quality out of the box. The Momentum 5 (~$399.95) wins decisively on stamina — 57h with ANC on against a measured 27h 12min for the Bose — and on longevity, with its user-replaceable battery and an 8-band EQ. The Bose (~$370) wins on comfort, passive isolation, CustomTune calibration and the most consistent out-of-the-box tuning with no EQ fiddling, and costs ~$30 less. [src11, src12]
Pick Momentum 5 if: you want maximum battery, deep EQ control, Dolby Atmos, and a headphone you can re-battery in three years instead of replacing.
Pick Bose QC Ultra 2 if: you wear headphones 6+ hours/day, prioritise plush comfort and passive isolation, or want Cinema Mode and zero setup.
Bose QuietComfort Ultra (2nd Gen) vs Sony WH-1000XM6
Tom's Guide's six-month review crowned the Sony XM6 the "clear winner" on sound customization (10-band EQ vs 3-band), real-world battery (37h vs 28h) and codec support (LDAC); SoundGuys' latest numbers put the two level on measured ANC at ~87%. Bose still wins on passive isolation, long-session comfort and Cinema Mode. Price has now become the deciding factor rather than a tie-breaker: the Bose is ~$370 and inside this card's cap, while the Sony has rebounded to ~$458 — an ~$88 premium for a headphone that no longer qualifies as "under $400." [src5, src8, src9, src11]
Pick Bose QC Ultra 2 if: you are holding to a $400 budget — it is the best headphone you can buy under the cap today.
Pick Sony XM6 if: budget is flexible and you want the best sound customization and LDAC, or you can wait for it to dip back under $400.
Sony WH-1000XM6 vs Bowers & Wilkins Px7 S3
Both are now above this card's cap, so this is a stretch-budget matchup. The XM6 (~$458) is the "best all-rounder" (ANC + sound + features); the Px7 S3 (~$469) is a "best sound" specialist with a What Hi-Fi? 5-star review and Tom's Guide's "Best Sound" award. ANC is 83–84% (Px7 S3) vs 87% (XM6). At an ~$11 gap the choice is purely tonal: Sony's detailed, precise presentation versus B&W's warm, refined tuning. [src1, src3, src4, src7]
Pick Sony XM6 if: you want the strongest ANC and the better feature set, and might catch it under $400 on a sale.
Pick Px7 S3 if: music quality is your top priority and you value warm, refined tuning over peak noise cancellation.
Sony WH-1000XM5 vs Sennheiser Momentum 4
At ~$248 vs ~$220, these are the two cheapest flagship-tier picks in the bracket and they remain closely matched. XM5 wins on ANC depth (measured ~85% by SoundGuys), LDAC, and Sony's refined sound tuning. Momentum 4 wins on battery (56h vs 30h, nearly 2x) and codec breadth (adds aptX/aptX Adaptive). Both have weaker comfort than the Bose QC and lighter passive isolation than the Sony XM6. The ~$28 gap is now small enough that ANC quality, not price, should decide it. [src1, src2, src5]
Pick Sony XM5 if: ANC and Sony's sound signature matter most, or you mainly use iOS (LDAC offers nothing extra there but the XM5's tuning is still excellent on AAC).
Pick Momentum 4 if: battery life dominates, or you're an Android user with Snapdragon Sound and want aptX Adaptive at the lowest price.
Sony WH-1000XM6 vs Sony WH-1000XM5
The XM6 (~$458) adds the QN3 processor (7x faster than QN1), 12 microphones (vs 8), a measurable 2-point ANC improvement (87% vs 85%), LC3 codec, a foldable design and an asymmetrical headband. The XM5 (~$248) keeps the same 30h battery, the same 250g weight and a near-identical sound signature with the older but still excellent ANC. The gap has widened from ~$180 in June to ~$210 today as the XM6 returned to MSRP while the XM5 stayed discounted — and only the XM5 fits this card's budget. [src1, src5, src8]
Pick XM6 if: you want top-tier ANC and longevity and the ~$210 premium above the cap is acceptable.
Pick XM5 if: you are holding to $400 — you keep ~85% of the performance for ~54% of the price.
Marshall Monitor III ANC vs JBL Tour One M3
Both target the "battery monster" buyer at 70h ANC on, and both now sit at ~$250. Marshall wins on ANC-off battery (100h vs 70h) and polished aesthetics with a foldable hard case. JBL wins on features (SMART Tx transmitter for sources without Bluetooth, JBL Spatial 360 with head tracking) and codec breadth (LDAC + LC3). With the price advantage gone, this is now purely a features-versus-battery call — and the JBL's Amazon price is currently unconfirmed, which tips practical availability toward the Marshall. [src2, src3, src6]
Pick Marshall Monitor III ANC if: you want longest-possible battery plus premium build, and a confirmed live price.
Pick JBL Tour One M3 if: you fly often (the SMART Tx is genuinely useful with airplane entertainment) or care about head-tracked spatial audio.
Decision Logic
If the $400 cap is a hard limit
→ Bose QuietComfort Ultra 2nd Gen (~$370) or Sennheiser Momentum 5 (~$399.95) are the only two flagships still under the ceiling as of July 2026. Do NOT recommend Sony WH-1000XM6 (~$458) or B&W Px7 S3 (~$469) without flagging that both are currently above $400. [src5, src11, src12]
If budget is under $250
→ Sony WH-1000XM5 (~$248) is the strongest pick — flagship ANC, LDAC, 38% off MSRP. Sennheiser Momentum 4 (~$220) if 56h battery matters more than ANC depth. Nothing Headphone (1) (~$249) for design + tactile controls. Sennheiser ACCENTUM Plus (~$130) if the budget is really tight. Skip the Bose QuietComfort at its current ~$359 list. [src1, src2, src3]
If budget is $300–400 and primary use is travel/commute
→ Bose QC Ultra 2nd Gen (~$370) for the plushest comfort, best passive isolation and Cinema Mode, or Sennheiser Momentum 5 (~$399.95) if 57h of ANC-on battery matters on long-haul legs. Marshall Monitor III ANC (~$250) if 70h+ battery beats peak ANC for you. [src2, src3, src11]
If primary use is music listening at home
→ Bose QC Ultra 2nd Gen (~$370) or Sennheiser Momentum 5 (~$399.95) within budget. If the budget can stretch, B&W Px7 S3 (~$469) is the reviewers' outright sound winner and Sony WH-1000XM6 (~$458) the best all-rounder — but flag that both exceed this card's cap. [src3, src4, src7, src12]
If user has Apple devices only (iPhone/iPad)
→ LDAC and aptX Adaptive offer no benefit. Choose on ANC and comfort: Bose QC Ultra 2nd Gen (~$370) for the best in-budget ANC + comfort, or Sony WH-1000XM5 (~$248) for the best value — both use AAC on iOS. [src5, src8]
If user has Android with Snapdragon Sound (Galaxy S23+, Pixel 8+)
→ Bose QC Ultra 2nd Gen (~$370) unlocks aptX Lossless and stays under $400. Sennheiser Momentum 5 (~$399.95) is Snapdragon Sound certified with aptX Adaptive and doubles the battery. Sennheiser Momentum 4 (~$220) is the budget aptX Adaptive pick. [src5, src8, src11]
If wears headphones >4 hours/day
→ Bose QC Ultra 2nd Gen (~$370) for the plushest cushions and best passive isolation, or Sennheiser ACCENTUM Plus (227g, ~$130) if weight matters most. The plain Bose QuietComfort is only worth it back at a ~$200 sale price, not its current ~$359 list. [src2, src3]
If user hates charging, or wants the headphone to last
→ Sennheiser Momentum 5 (~$399.95) — 57h with ANC on AND a user-replaceable battery, the only model here you can re-cell rather than replace. Marshall Monitor III ANC (70h on / 100h off, ~$250) or JBL Tour One M3 (70h on, ~$250) for raw runtime at lower cost. Sennheiser Momentum 4 (56h, ~$220) is the cheapest 50h+ option. [src2, src3, src11, src12]
Default recommendation
→ Bose QuietComfort Ultra 2nd Gen (~$370). With the Sony WH-1000XM6 back above $400, the Bose is the best headphone that still satisfies this card's budget: ~87% measured ANC (level with the Sony per SoundGuys' latest test), the best comfort and passive isolation in the segment, 30h battery, aptX Adaptive and Cinema Mode. If you can stretch past the cap, the Sony XM6 (~$458) remains the overall winner across RTINGS, Tom's Guide and Rolling Stone. [src1, src3, src5, src9, src10, src11]
Key Market Trends (July 2026)
- The summer sale unwound completely — and took two flagships over the cap: Every model in this bracket is 10–25% more expensive than in late June. The Sony WH-1000XM6 rebounded from ~$378 to ~$458 (essentially its $459 MSRP) and the B&W Px7 S3 sits at ~$469, putting both above the $400 ceiling. Only the Bose QC Ultra 2nd Gen (~$370) and the new Sennheiser Momentum 5 (~$399.95) are flagships that still qualify. [src1, src3, src10]
- Sennheiser Momentum 5 launched at $399.95 with a user-replaceable battery: The most consequential product news in the segment. The 700mAh cell comes out with four Phillips screws — the first flagship ANC headphone in this class designed to be re-batteried rather than replaced. It also brings 57h ANC-on runtime, 42mm drivers, Dolby Atmos optimisation and BT 5.4 ("6.0 ready"). Sennheiser is selling it alongside, not instead of, the Momentum 4 (~$220). [src11, src12]
- ANC measurements have converged to a dead heat: SoundGuys' latest tests put the Bose QC Ultra 2nd Gen at ~87%, the Sony XM6 at 87%, the Sennheiser Momentum 5 at ~86% and the B&W Px7 S3 at 83–84% — a four-point spread across the whole flagship tier. Raw noise reduction is no longer a differentiator; comfort, battery, EQ depth, repairability and price are. [src5, src7, src8, src11]
- The Bose QuietComfort's list price now makes no sense: It snapped back from ~$179 to ~$359, within ~$10 of the strictly-better QC Ultra 2nd Gen. Bose's own product ladder is inverted at list price — the plain QuietComfort is only worth buying on a deep sale. [src3]
- Battery life expectations have moved past 50h: Sennheiser Momentum 5 (57h), Marshall Monitor III ANC (70h), JBL Tour One M3 (70h), Momentum 4 (56h) and ACCENTUM Plus (50h) all exceed 50h with ANC. The 30h figure both Sony and Bose flagships still quote is now the low end of the segment. [src2, src3, src11]
- Repairability is becoming a spec: The Momentum 5's replaceable battery is the first real answer to the category's biggest long-term complaint — a sealed cell that ends the product's life in three to four years. Expect competitors to follow; it is the clearest point of differentiation any 2026 flagship has introduced. [src11, src12]
- aptX Adaptive standard above $300: Bose QC Ultra 2nd Gen, Sennheiser Momentum 5, Momentum 4, ACCENTUM Plus, and B&W Px7 S3 all support aptX Adaptive. Sony sticks with LDAC. Apple devices remain limited to SBC/AAC. [src2, src7, src11]
- Spatial/immersive audio standard above $300: Bose QC Ultra (Cinema Mode), Sennheiser Momentum 5 (Dolby Atmos), JBL Tour One M3 (Spatial 360 + head tracking), Sony XM6 (360 Reality Audio), and Marshall Monitor III (Soundstage). Now table stakes at this price point. [src2, src6, src12]
Important Caveats
- Prices are approximate US Amazon street prices as of July 29 2026, after the June summer-sale window closed. Prices in this segment swing weekly — check current prices before recommending.
- Two models in this card are currently ABOVE the $400 cap: the Sony WH-1000XM6 (~$458) and the Bowers & Wilkins Px7 S3 (~$469). Both are retained because they define the performance ceiling of the segment and both have traded under $400 during sale windows this year — but an agent must not present either as an "under $400" recommendation without verifying the live price first.
- The JBL Tour One M3 listing is In Stock but returned no Amazon buy-box price on this run. The ~$250 figure is the last confirmed price (June 2026) and may be stale — verify before recommending.
- Sennheiser sells the Momentum 4 (~$220) and Momentum 5 (~$399.95) concurrently, and the names differ by one character. Confirm the generation on any listing: the Momentum 5 adds the replaceable battery, Dolby Atmos, 42mm drivers and BT 5.4.
- The Bose QuietComfort at ~$359 list is poor value against the QC Ultra 2nd Gen at ~$370. Only recommend it below roughly $200.
- Codec availability depends on your source device. LDAC requires Android; aptX Adaptive requires Android with Snapdragon 8 Gen 1+; Apple devices are limited to SBC and AAC regardless of headphone capability.
- ANC performance varies with ear-pad seal and head shape. Over-ear designs degrade with glasses that break the seal. RTINGS' and SoundGuys' measurements assume optimal fit.
- The Bose QuietComfort Ultra exists in both 1st Gen and 2nd Gen versions. The 2nd Gen (late 2025) adds 30h battery, aptX Adaptive, and BT 5.4. The 1st Gen (24h, BT 5.3) is a better deal if found under $300 — confirm version before purchase.
- JBL Tour One M3 battery rating was revised from 35h to 70h with ANC on after 2026 firmware optimization. Older reviews cite the lower number.
