Replacement Audio Cable Cord, Extension Wire 3.5mm to 2.5mm for Bose QuietComfort QC45 QC35II QC35 QC25 NC 700 Soundlink Soundtrue Headphones Black
Best for: Broad compatibility across several Bose over-ear generations
This is the most flexible option if you own a QuietComfort or NC 700 model and are not sure which cable the headphones originally shipped with. Its listing name covers a long run of Bose over-ear and on-ear models, so it suits owners who want one cable that can cover more than one pair in the house.
Key specs

- Black finish
- Extension-style wire for standard audio input
Pros
- Covers many QuietComfort and NC 700 models in a single listing
- Standard 2.5mm end matches the common Bose cable port
- Easy to identify by the connector sizes in the listing
Cons
- Broad compatibility means you should still confirm your exact model before ordering

Audio Cable Cord Wire Replacement for Bose QuietComfort 15, Bose QuietComfort 2, QC15, QC2 Headphones, Headphone Extension Cable (1.4m)
Best for: Older QuietComfort 15 and QuietComfort 2 headphones

Key specs
- Listed length of 1.4 m
- Designed for Bose QuietComfort 15 and QuietComfort 2 headphones

Replacement Aux Extension Cable Cord Wire,for Bose QuietComfort QC25 QC35 Sound Link SoundTrue On Ear Headphones with in Line Mic Volume Control (Black)
Best for: Calls and volume control on QC25 and QC35 headphones
If your original cable carried a microphone and volume buttons, replacing it with a plain audio cable removes that function. This listing is built around the in-line mic and volume control, making it a practical choice for people who take calls or adjust volume from the cable.
Key specs
- In-line microphone and volume control, as stated in the listing
- Black finish
- Compatible with QuietComfort 25 and 35 as named
Pros
- Keeps mic and volume controls, unlike audio-only cables
- Clearly names the supported QC25 and QC35 models
- Useful for hands-free calls with a wired connection
Cons
- In-line controls depend on compatible device support, which owners sometimes report as inconsistent
- Not a fit for headphones that use a different connector layout
Bottom line: The right choice when call and volume controls on the cable matter more than a minimal design.

For listeners who use wired audio without calls, a plain cable is often enough. This white cable lists support for the NC 700 and QC45 along with earlier QC25, QC35 and QC35II models, and it omits the microphone to keep the design simple.
Key specs

- White finish
Pros
- Lists NC 700 and QC45 compatibility, which some alternatives do not
- Simple audio-only design with fewer components to fail
- White color may suit owners who prefer a lighter cable
Cons
- No in-line mic or volume control
- Owners who want a calling cable should choose a model with a microphone
Bottom line: A good match for NC 700 or QC45 owners who want a basic wired connection for listening only.

Best for: Budget repair of QC15 headphones that use an in-line mic
When the cable is the only broken part and the earcups still work, a cable-only replacement keeps the repair simple. This listing targets the QC15 with an in-line microphone, which covers owners who used the headset for calls as well as music.
Key specs
- Cord-only replacement, as stated in the listing
- In-line microphone for QC15

Buying Guide
Confirm your exact headphone model
Bose used several connector layouts and cable generations across its QuietComfort, NC 700, SoundLink and SoundTrue lines. Check the model name printed inside the earcup or on the original box before ordering. Compare that name against the compatibility text in each listing, not just the family name.

Connector type and size
Most of these cords use a 3.5mm plug on the source end and a 2.5mm plug on the headphone end. Confirm both ends before buying. A mismatched 2.5mm or 3.5mm connector will either fail to fit or fail to make a reliable contact.

Microphone and volume control
If you take calls or adjust volume from the cable, choose a cord with an in-line microphone and controls. Audio-only cords are simpler, but they remove those functions. Decide which you need before comparing prices or features.

Cable length
Length affects comfort more than most buyers expect. A longer cable is convenient for travel or a sofa, while a shorter one keeps cords tidy at a desk. Check the length stated in the listing and measure your current cable if you want a close match.

Strain relief and durability
Owners often report that cords fail near the plugs, where bending stress is highest. Look for listings that describe reinforced or flexible jacketing at the connectors. Avoid coiling the cable tightly around the earcup, which accelerates wear.

Cable-only versus full headphone repair
A cable-only replacement makes sense when the earcups, battery and drivers still work. If the headphones have other damage, such as a failed battery or a broken earcup hinge, a cord alone will not solve the problem. For those issues, consult Bose support or a qualified repair service.

Use case: listening, calls or travel
Match the cable to how you actually use the headphones. Listeners on a plane or in an office often want a basic cable, while those on frequent calls need the microphone. If you carry the headphones daily, a durable cord with clean strain relief is worth more than a minimal design.

FAQ
Can I use any 3.5mm cable with my Bose headphones?
Not reliably. Bose headphones use a 2.5mm connector on the earcup side, so you need a cable with a matching 2.5mm plug. Many generic cables use a different connector and will not fit or may not connect properly.
How do I know which replacement cord fits my model?
Check the model name on your headphones and compare it with the compatibility text in each listing. Listings that name a specific generation, such as QuietComfort 15 or NC 700, are usually the safest match.
Do I need a cord with a microphone?
Only if you plan to take calls or use the in-line volume controls from the cable. If you only listen to music or audio, an audio-only cord is simpler and avoids features you will not use.
Why does my cable crackle even after replacing it?
Crackling can come from a loose plug, a damaged jack on the headphones or a source device with a worn port. Try reseating both ends and testing with another source. If the problem continues, the headphone jack may need professional inspection.
Is it worth replacing only the cable instead of the whole headset?
Often yes, when the earcups, battery and sound quality are still good. A cable-only repair costs far less than a new headset, but it will not fix other failures. Weigh the age and condition of the rest of the headphones before deciding.
Can I repair the original cable myself?
Some owners re-solder connectors or replace strain relief, but this requires basic electronics skills and can damage the headphones if done poorly. If you are not comfortable with soldering, a replacement cable is the safer option.
Conclusion
For most owners of a range of Bose over-ear models, the broadly compatible 3.5mm to 2.5mm cable is the most versatile starting point. If you use calls or volume control, choose the in-line mic version for QC25 and QC35. QC15 and QC2 owners should pick the model-specific cords, and budget repairs for QC15 with in-line mic are covered by the cable-only option. Confirm your exact model first, and the right bose headphones cord replacement will be straightforward.
