Cypher.V Replacement Aux Cable Cord Wire, 3.5mm to 2.5mm for Bose NC700 QuietComfort QC25 QC35 QC35II QC45 Headphones (No Mic) (White)
Quick take
This Cypher.V replacement aux cable wire is made to restore a wired connection between a 3.5mm audio source and Bose QuietComfort on-ear headphones that use a 2.5mm plug. It uses a straight, male-to-male 3.5mm to 2.5mm design with a 140 cm (4.6 ft) length and a flexible TPE jacket intended to resist tangles. The key thing to double-check is connector contact fit for your specific headset, since compatibility is not always guaranteed for every cable port.
Pros and cons
Pros
- Designed for specific Bose QuietComfort models that use a 2.5mm headphone connection (including NC700, QC45, QC35II, QC35, QC25).
- 3.5mm to 2.5mm male-to-male aux connection (straight gold-plated plugs).
- About 140 cm (4.6 ft) length for typical desk, couch, or travel setups.
- Flexible TPE cable cover aimed at reducing knots and improving handling.
Cons
- Connector/contact fit may vary by device, so it is important to confirm your headphone’s exact port requirement.
- It is a wired-only replacement, so it will not add or enable any wireless features to your Bose headphones.
What buyers think
Buyer-review evidence is generally positive, with multiple reports that the cable works as intended and matches Bose headsets that require an aux cable connection. Review themes focus on simple functionality (plug-in and audio works), and many buyers describe it as a good replacement for older Bose headphones.
What this cable is for
This is a replacement aux cable wire for Bose QuietComfort on-ear models that use a 2.5mm headphone-side connection and a 3.5mm audio source-side connection. In practical terms, you can use it when your existing cable is damaged, lost, or no longer provides a reliable connection.
Key specs that matter for buying
Connector type and compatibility
The cable is a 3.5mm to 2.5mm, male-to-male aux cable with a straight plug design. It is listed for Bose NC700 and several QuietComfort models including QC45, QC35II, QC35, and QC25, plus some additional Bose-compatible lines. Because connector fit is essential, confirm your exact Bose model and the port type on your headset before ordering.
Length and build
Length is approximately 140 cm (4.6 ft). The jacket is described as TPE (thermoplastic elastomer), intended to be flexible and more resistant to tangling and pulling than stiffer cable types. The cable weight is listed as about 11 grams, which is typical for a lightweight replacement cord.
Pros and cons in plain English
Where it fits best
- You have a compatible Bose QuietComfort headset and need a wired replacement aux lead.
- You want a straightforward plug-in solution with a moderate 4.6 ft length for everyday listening.
- You care about cable handling, since the flexible TPE jacket is aimed at reducing knots.
Who should be cautious
- If you are unsure about your headset’s exact port (or you have a different Bose variant than the listed models), compatibility can be hit or miss, so it is worth double-checking before committing.
- If you expect wireless use, this cable will not change anything, it is simply an aux replacement.
Verdict
If your Bose QuietComfort headset uses a 2.5mm headphone connection and you need a replacement aux cable, this Cypher.V 3.5mm to 2.5mm cord is a practical, lightweight option with a reasonable length and a cable jacket designed to be easy to live with. The main buying caveat is ensuring the connector contact fit matches your specific device, since that is the only notable compatibility snag mentioned by buyers.
