Mr Rex 3.5mm to 2.5mm Aux Cable Cord for Bose 700 QuietComfort Ultra QC45 QC35II QC35 QC25 Noise Cancelling Headphones, JBL E45BT E55BT E65BTNC Bluetooth Earphone, Audio Replacement Wire (1-Pack, 5FT)

Has worked out perfectly. Just as described. This is a replacement for a cable that was going bad.

Got these for my son’s headset: he has a set with soft ear pads to help with his sensory issues and to listen to music, which also has a mini USB port for charging. The cord that came with trailed after ac while, and the one I found did not have any sounds coming out of it (not sure if it wasn’t the right kind?). So I bought this one. All of a sudden we can finally hear sounds again and he’s super happy of listening to his music again. It’s a good deal for price sand it came quickly. Seems well made as it should not frail as quickly also because of the angled plug in part. I can’t adjust the volume on the headsets themselves, so I don’t know if it’s because the buttons are broken, or if this cord doesn’t allow for it, but either way it’s fine with me (no the cord does not have volume up/down buttons like on other headphones). Music isn’t too loud on headset itself anyway, so we’re good. Thumbs up.

I bought this well made and inexpensive little cable to connect a cell phone (3.5 mm) to my Polycom Soundstation (2.5 mm). It works great with my Android phone and my wife's iPhone 6s. If you have a newer iPhone I'm guessing you'll need a lightning connector to 3.5 mm female adapter. Much cheaper than the connector sold by Polycom!! Just tried it with an iPhone 7 that only has a lightning connector, no 3.5 mm headphone jack. I used an adapter to connect to the lightning connection. It did NOT work well. There was some sound, but it was like the speaker phone wasn't always getting a signal and would shut off, then it was too slow to pick up on the new signal when someone started talking. Oh well, it was worth a try. Still a good cable.

The cable works, but I did have to take an angle grinder to it to make it fit, but I don’t think that would be a super common problem

Great price + quality, would buy again.

Quality cable, use it to plug my headphones into my laptop.

The cord quit working properly just after the return window closed. The left side intermittently fades out. Verified that the Bose speakers do not have a problem because sound is perfect when using Bluetooth. Disappointing

Works great with Phillips 8000 seroes headphones. Sound is great!
