Replacement Audio Cable Cord (3.5mm to 2.5mm) for Bose QuietComfort, SoundLink, Soundtrue
Quick take
This 3.5mm to 2.5mm male-to-male replacement audio cable is built for select Bose QuietComfort, SoundLink, Soundtrue, and OE2/OE2i headphone models. It’s a straightforward plug-in replacement with a 1.4 m (4.6 ft) length, but you should double-check your headphone’s connector type before buying.
Pros and cons
Pros
- Designed for compatible Bose models including QuietComfort QC25, QC35, QC35 II, QC45, NC 700, SoundLink, Soundtrue, and OE2/OE2i.
- 3.5mm to 2.5mm male-to-male plug design, intended for quick plug-and-play use.
- 1.4 m/4.6 ft cable length that’s easier to use than very short replacements.
- Buyers describe it as a functional replacement that helps restore audio connection.
Cons
- Compatibility is model- and connector-specific, so it may not work if your Bose headphone uses a different jack size.
- Review evidence is limited mostly to “replacement worked,” so performance claims beyond fit and functionality are harder to verify.
What buyers think
Buyer feedback for this replacement cable is relatively consistent in theme: it’s viewed as an inexpensive part that gets older Bose headphones working again, including use cases like listening while traveling. Multiple reports mention a proper fit and that audio is restored when the cable is connected. Beyond that, the review evidence is too limited to draw a strong pattern about nuanced audio quality differences, long-term durability, or noise performance.
Who this replacement cable is for
This cable is a good fit if you need a replacement audio cord for specific Bose headphone lines that use a 2.5 mm headphone-side connection and a 3.5 mm device-side connection.
- Best for Bose owners with QuietComfort (QC25, QC35, QC35 II, QC45), NC 700, SoundLink, Soundtrue, and OE2/OE2i who want a wired replacement solution.
- Best for anyone who prefers a simple, male-to-male plug connection to restore listening without changing headphones or audio gear.
Compatibility and connector details to check first
Before you buy, confirm two things: (1) your headphone model matches the supported Bose lineup, and (2) your headphones use a 2.5 mm audio input on the earcup. This cable is labeled as a 3.5mm to 2.5mm AUX cable with male-to-male connectors and a 1.4 m (140 cm) length.
If your headphones do not use a 2.5 mm port, this type of cable will not be the right physical match, even if your device has a 3.5 mm headphone jack.
Audio connection experience
From the buyer-reported outcomes, the main value is getting back to “it works” audio listening through a replacement cord. The cable is described as enabling stereo sound transmission and is marketed as having low-noise performance, but the review evidence provided focuses more on fit and functionality than on measurable audio quality changes.
Pros and cons, in plain English
Pros
- Correct use case for wired Bose headphone replacement repairs.
- Reasonable length for everyday use (about 4.6 ft).
- Clear connector format (3.5mm to 2.5mm, male-to-male), which helps reduce “will it plug in?” uncertainty.
Cons
- Don’t buy by brand alone. You need both the right Bose model and the right 2.5 mm headphone-side connection.
- Limited detail on long-term performance in the available feedback, so treat durability expectations as unverified beyond basic functionality.
Price and availability
This is positioned as a low-cost replacement part (listed around $7.99, with an original list price shown). It’s currently marked in stock, making it easier to grab a replacement without waiting for availability to change.
Alternatives to consider
If you’re not confident about connector compatibility, you may want to compare alternatives by the same buying criteria: matching your exact headphone-side jack size (2.5 mm), getting the correct device-side plug (3.5 mm), and choosing a length you’ll comfortably reach from your phone or laptop.
- Different-length replacements: useful if you routinely sit far from your audio source and want less cable tension.
- Other OEM-style replacements: consider them if you prioritize guaranteed model-level fit (especially when you are unsure about your current connector type).
Verdict
If you own one of the supported Bose headphone models and you specifically need a 3.5mm to 2.5mm replacement cable, this cord is a practical, budget-friendly way to restore wired listening. The biggest caveat is simple: confirm the 2.5 mm headphone-side connector match first, since compatibility is the make-or-break factor for this kind of replacement.
FAQs
Will this replacement cable work with my Bose QC45 or QC35?
It’s intended for Bose QuietComfort QC45 and QC35 models (including QC35 II). If your headphone uses the same 2.5 mm audio input, it should be the right physical match.
Is this cable an audio extension or a replacement cord?
It functions as a wired audio cord replacement with 3.5mm to 2.5mm male-to-male plugs. It’s meant to connect your Bose headphone to a device with a 3.5 mm jack.
What is the cable length?
The cable length is 1.4 m (140 cm), or about 4.6 feet.
Does it work with iPhones and Android phones?
Because it uses a 3.5 mm connector on the device side, it’s compatible with devices that have a 3.5 mm headphone jack.
