Bose 700 Review in 2026: Still Worth Buying Refurbished?

The Bose Noise Cancelling Headphones 700 launched in 2019 as a deliberate break from the QuietComfort formula. Out went the folding plastic travel design; in came a stainless-steel headband, touch controls, eleven levels of noise cancelling you could dial like a volume knob, and a microphone system built to make your voice sound clear in a noisy street. It was Bose’s flagship for four years — and then it was gone, replaced first by the QuietComfort Ultra in 2023 and then by the QuietComfort Ultra 2nd Gen in 2025.

SoundMavericks has not hands-on tested the 700 for this review. This is a research- and specification-based assessment built from Bose’s published specifications, the current Amazon listing data we verified for this article, and the long review record from the model’s years on sale. Where a claim depends on age — battery health above all — we say so plainly rather than repeating the 2019 launch figures as if they still apply to every unit on sale today.

Bose Noise Cancelling Headphones 700 — Black

What the Bose 700 Was: The 2019 Flagship in Brief

To judge a refurbished 700 fairly, you have to remember what it was competing against. In 2019 the fight was Bose versus Sony’s WH-1000XM3, and Bose won the call-quality battle outright. The 700 uses an eight-microphone system: six microphones feed the noise cancelling, and four work on your voice, isolating it from wind and crowd noise. Reviewers at the time consistently rated it the clearest calling headset in its class, and that reputation has survived — it is the main reason used units still hold their value with remote workers.

The other headline was control. Where the QC35 II offered high, low and off, the 700 offered eleven levels, from full silence down to a transparency setting that let conversation and traffic in. A button on the left earcup cycled favourite levels, touch gestures on the right earcup handled volume and tracks, and the Bose Music app added EQ in a later firmware update. Battery was rated at up to 20 hours with noise cancelling on, charged over USB-C — modern for its day.

What it never had matters just as much in 2026. There is no aptX or LDAC — just SBC and AAC. There is no spatial audio. The earcups do not fold flat into a small ball; they rotate flat and ride in a large, slim case. And Bose’s augmented-reality audio experiment, Bose AR, was quietly abandoned, so do not let any old listing copy persuade you it is a feature worth paying for today.

Bose 700 Specifications

Specifications from Bose’s published data for each model. Battery figures are the when-new ratings — see the battery-aging section below before applying the 700’s figure to a refurbished unit.

Sound Quality and Noise Cancelling in 2026

The 700’s sound signature was always the polite one: balanced, slightly bright, with bass that is present rather than pumped. Bose’s volume-optimised Active EQ keeps that balance consistent at low and high volumes, which suits long listening sessions and podcasts as much as music. Against a current QuietComfort Ultra, the 700 gives up low-end authority and the Ultra’s Immersive Audio spatial mode — music sounds flatter and narrower by comparison. Against the headphones most people actually cross-shop at refurbished prices, though, it still sounds like what it was: a flagship.

Noise cancelling tells a similar story. Eleven adjustable levels was class-leading thinking in 2019, and at maximum the 700 still erases engine drone and air-conditioning hum very effectively. What newer Bose models do better is the messy middle of the spectrum — voices, keyboard clatter, café noise — where CustomTune calibration and newer processing in the Ultra line pull ahead. Our QuietComfort Ultra review covers that newer system in full, and our guide to the best noise cancelling headphones shows where the whole current field stands.

The Honest Part: What Refurbished and Renewed Buying Actually Gets You

Battery aging is the real specification

Every Bose 700 on sale today was manufactured between 2019 and roughly 2023. Lithium-ion batteries lose capacity with time and charge cycles whether the headphones were used daily or sat in a drawer, and the 700’s battery is sealed inside — there is no official user replacement. A when-new rating of 20 hours can mean 16–17 hours on a lightly used unit and considerably less on a hard-used one. That is still enough for most workdays and long flights, but it is the single biggest variable between two listings that otherwise look identical, and it is why the grading and guarantee behind a unit matter more than a small difference in asking price.

Bose refurbished vs Amazon Renewed vs marketplace used

There are three distinct ways to buy a 700 now, and they are not equivalent. Bose refurbished stock, sold through Bose’s own refurbished outlet, is inspected and certified by Bose itself and typically carries a Bose warranty — the closest thing to buying new, and usually the first place to check. Amazon Renewed units are inspected and tested by Amazon-qualified suppliers and are backed by the Amazon Renewed Guarantee, which promises a replacement or refund if the product does not work as expected; the listing we verified for this article is the original Bose 700 listing in black, where remaining stock is limited and buying options include Renewed and used offers. Plain marketplace used units are the cheapest and the riskiest: no standardised battery testing, no guaranteed accessories, and condition descriptions that vary wildly by seller. Our advice: buy Bose refurbished first, Amazon Renewed second, and marketplace used only with a returns window you trust.

What to check on any unit

Whichever route you take, check the same five things in the first days of your return window. Run the battery from full to empty once and compare it with the 20-hour when-new rating. Inspect the ear cushions — the 700’s protein-leather cushions are replaceable, and peeling or collapsed foam is a bargaining point, not a deal-breaker. Test the touch panel across its full surface, test both physical buttons, and make a call from somewhere noisy: microphone degradation is rare, but a damaged mic array defeats the main reason to buy this model. Finally, update the firmware in the Bose Music app and confirm the app still recognises the headphones — current app support is part of what keeps a discontinued model usable.

The Successor Chain: What Replaced the 700

The 700 was not replaced by one headphone but by a line. The QuietComfort Ultra (2023) took the flagship role: Bose’s strongest noise cancelling, Immersive Audio spatial sound, Snapdragon Sound with aptX Adaptive, and up to 24 hours of battery. The QuietComfort Ultra 2nd Gen (2025) then stretched battery to 30 hours, added Bluetooth 5.4, wired lossless USB-C audio and a Cinema Mode for video. Below them sits the standard QuietComfort model — USB-C, multipoint and up to 24 hours in Bose’s classic folding design — for buyers who want new-with-warranty Bose calm without flagship extras. We compare the Ultra 2 directly with Sony’s flagship in our Sony WH-1000XM6 vs Bose QuietComfort Ultra 2 comparison.

Who Should Buy a Refurbished Bose 700 — and Who Should Not

Buy one if your day is full of calls and meetings and you want the clearest voice pickup Bose ever put in a consumer headphone of its era, if you prefer the 700’s slim, grown-up design to the chunkier QuietComfort look, and if a graded unit with a guarantee costs clearly less than a new standard QuietComfort. That is a real, defensible purchase in 2026 — the fundamentals were flagship-grade and the weak points are known and testable.

Skip it if you need maximum battery for multi-day trips without charging, if you use an Android phone that supports higher-quality Bluetooth codecs the 700 cannot accept, if spatial audio matters to you, or if the refurbished asking price has drifted close to a discounted current model — at that point the new product’s warranty, fresh battery and longer support life win every time.

Frequently Asked Questions

Did Bose discontinue the 700 headphones?

Yes. Bose discontinued the Noise Cancelling Headphones 700 as the QuietComfort Ultra line took over the flagship slot. Remaining Amazon stock is limited, and much of what is sold today is Renewed, refurbished or third-party marketplace stock rather than fresh factory-sealed retail units.

Are the Bose 700 still worth buying in 2026?

They can be — if you buy a graded refurbished or Amazon Renewed unit with a return window and you value call quality and design over battery life and modern codecs. If the refurbished price creeps close to a discounted current QuietComfort or QuietComfort Ultra, buy the current model instead.

How long does the Bose 700 battery last, and does it age?

Bose rated the 700 at up to 20 hours with noise cancelling on. The battery is not user-replaceable, and lithium cells lose capacity with age and charge cycles, so a heavily used early unit may deliver noticeably less. A graded refurbished unit with a tested battery is the safer buy.

What is the difference between Bose refurbished and Amazon Renewed?

Bose refurbished stock is inspected and certified by Bose itself and sold through Bose’s own refurbished outlet, typically with a Bose warranty. Amazon Renewed units are inspected and tested by Amazon-qualified suppliers and carry the Amazon Renewed Guarantee, which provides a replacement or refund if the product does not work as expected.

Bose 700 vs QuietComfort Ultra: which should I buy?

The QuietComfort Ultra and Ultra 2nd Gen cancel more noise, last longer per charge, support newer Bluetooth and spatial audio, and come with a full new-product warranty. The 700 only wins on price when refurbished stock is cheap, and on its slimmer design and still-excellent call microphones.

Can you use the Bose 700 wired when the battery is flat?

Yes. The 700 ships with a 2.5mm-to-3.5mm audio cable and can be used as a passive wired headphone when the battery is empty, although noise cancelling and touch controls need battery power.

Final Verdict

The Bose 700 did not stop being good when Bose stopped making it — it stopped being new. Treated as what it now is, a refurbished-market headphone, it earns an 8.2 from us: flagship call quality and design, honest compromises on battery age and connectivity. Buy it graded, buy it guaranteed, and buy it only while it stays clearly cheaper than the current QuietComfort line it inspired. If it does not, the successors above are the same idea, finished.
