Mr Rex 2.5mm to 3.5mm Audio Cable Headphone Replacement Cord Nylon Braided Aux Cable Stereo Adapter for Bose 700 QuietComfort QC35II QC35 QC25 Headphones, JBL E45BT E55BT Headsets (10ft/3m, Black)

The cable that came with my Bose headphones was very thin and flimsy, this is way better, robust connectors and good quality braiding.

Bought this to replace the (rubber, non-braided) 3.5mm to 2.5mm TRS-TRRS cable which shipped with my Shure Aonic 50 headphones (also used in their Aonic 40 model). I can confirm it works perfectly for analog input to those headphones, and is a real physical improvement over the Shure cable. Even though it wasn't shown in the product photo, mine came with an additional 3.5mm to 1/4" TRS adapter that screws on to the larger connector, great for connecting to a sound board's monitor jack or higher-quality headphone amps. Metal spring-style strain-relief sleeves on both ends of the cable too, which also appear well-designed and built with quality. Edit: I've noticed other reviews mention acoustic coupling being an issue, due to the material and braiding. This means when physically rubbing/sliding the cable against a shelf, armrest, etc. it will transfer that vibration into the headphone its plugged into. That's certainly true and might make this particular style of braided cable inappropriate for certain ergonomic situations. But this physical vibration happens mechanically, not touching the electrical signal carried by the cable, so for a monitoring, mixing, recording etc. it's a non-issue. For my personal use so far, it's easy to ignore and desensitize to the cable rubbing sounds, but this will of course depend on the user and headphone model.

Lip on the 2.5mm connector side ensures it will fit into recessed headphone connectors. Seems to be good quality. Good length cable for PC audio interface.

Needed a longer cable to connect from my Bose QC 35 II headphones to my PC. This worked out perfectly. No complaints on product quality!

Considering the connectors are just 3.5mm and 2.5mm the cable feels great and is very strong. I don’t feel that it would snap if for some reason it was pulled on hard. Very happy with it.
