2.5mm to 3.5mm

Works amazing. It’s a perfect cord for my Bose headphones. It’s long, and it’s not too thin that you’re worried it’ll break easily. The end cable tilted is a nice feature. Better than the one it came with.

This is a very good quality cable for the price. It works perfectly as a replacement for the original cable supplied with my aging, but still functional, Nokia BH-905 headphones. I find the flexibility of the cable to be optimized to prevent tangling, which makes it easy to roll it up for storage..

I bought these for my Bose QCII. They have the tiny headphone jack on the left and needed them for the Switch before they added Bluetooth Audio, and when working at home on the computer.So I bought two of these. Not because they were bad and it wore out, but because I was a silly goose and broke the headphone jack while it was plugged in.Audio is good and clear and never had any issues with it. I like the little cable tie that comes with it. I appreciate the slight curve of the headphone jack.If I happen to break it again, I'll be back 😎

I purchased this cord for my headphones back in February after my JBL cord stopped working, and I will say it is definitely worth the price. The length is long (a bit inconvenient for me, but really nice in some situations) and nice and strong! At this point (July) I do have to replace it as it's stopped properly working but needless to say, 5 months of use for $5 isn't bad at all.

Airline broke my cable and I did not want to buy a Bose cable overseas for $25. Replacement cable works just fine.

Works great with my Bose QC35 headphones.

Fits snuggly for nearly all of my Bose headphones. Sound quality is awesome and is good when you don't have any battery left. Very cheap and easy to use.

Great value for the money. Easy to use. I am using with my bose headphones sound quality is good. Connecting etc no issues. Cable thickness as old iPhone cables. Quality better than I expected
