Bose no longer centers its headphone lineup on wired-only models, but wired listening has not disappeared. The legacy QuietComfort 25 was built around an audio cable and battery-powered noise cancellation, while current QuietComfort headphones combine Bluetooth with a detachable analog cable.
Quick answer: A legacy Bose wired model can still make sense if you already own one and its cable, pads, and battery system are in good condition. For a new purchase, current Bose QuietComfort models provide Bluetooth plus a cable, so the more useful question is whether their wired-mode behavior fits your source and listening needs.
Legacy QC25 vs. Current QuietComfort
| Factor | QuietComfort 25 | Current QuietComfort Headphones |
|---|---|---|
| Primary connection | Analog audio cable | Bluetooth plus 3.5 mm-to-2.5 mm audio cable |
| Power system | AAA battery for active noise cancellation | Rechargeable battery |
| Wireless audio | No Bluetooth audio | Bluetooth 5.1 listed by Bose |
| Cable use | Core listening path | Alternative to Bluetooth on compatible analog sources |
Bose introduced the QC25 in 2014 and described it as an around-ear noise-cancelling headphone with an inline cable and up to 35 hours of noise-cancelling operation from one AAA battery. Bose’s current QuietComfort specifications list Bluetooth 5.1, a rechargeable battery, and a 3.5 mm-to-2.5 mm audio cable in the box. See Bose’s QC25 announcement and current QuietComfort specifications.
Wired Does Not Automatically Mean “Lossless”
An analog cable removes Bluetooth transmission from the connection, but “wired” does not guarantee lossless end-to-end playback or better sound. The source file, streaming service, DAC, amplifier, headphone electronics, tuning, fit, and any active processing all remain part of the signal chain.
For the broader tradeoff, see when a wired backup is useful on wireless headphones.
Why Someone Might Keep a QC25
- The headphone already fits comfortably and the owner prefers its sound.
- The source device has a compatible analog output or adapter.
- Replaceable batteries are preferable to managing an internal rechargeable battery.
- The owner does not need Bluetooth or app-based features.
The practical limitation is support and parts availability over time. A legacy model should be judged by the condition of its cable, ear cushions, headband, battery contacts, and the source devices you plan to use.
Why a Current Hybrid Model Can Be Easier
A current Bluetooth model with a cable can serve both mobile wireless use and compatible wired sources. That flexibility is useful for travel, computers, and audio devices that still provide analog outputs. The exact microphone, controls, and active features available in cable mode are model-specific, so check the manual before assuming wireless functions carry over unchanged.
Bose Wired Headphones FAQ
Does Bose still make wired-only QuietComfort headphones?
Bose’s current QuietComfort headphones are Bluetooth models that also include an analog audio cable. The QC25 is a legacy wired model.
Can current Bose QuietComfort headphones be used with a cable?
Yes. Bose lists a 3.5 mm-to-2.5 mm audio cable with current QuietComfort Headphones. Check the manual for feature behavior in wired mode.
Does wired listening always sound better than Bluetooth?
No. Wired removes Bluetooth transmission, but overall sound depends on the source, conversion, amplification, processing, headphone tuning, and fit.
Is a used QC25 still practical?
It can be if the headphone, cable, pads, battery system, and source compatibility meet your needs. Parts condition and long-term support matter more on an older model.

Right on target. I go to the gym and 95% of people who have earbuds, have wireless. A few of us have wired, and like you say, no worries about battery charging, consistency, or having your ears blocked. I had the Bose QC25 ANC which were OK, and really had no rechargeable battery, but felt the pressure in my ears from the NC. But a drop in AAA battery that lasts 30 hours beats a planned obsolescent rechargeable battery. At 79, I figure I don’t need anymore electric devices in my ears. Thanks.
