Upgraded aptX Wireless Bluetooth Adapter for Bose QuietComfort 25 QC 25Headphones with Mic/Volume Control, Black

It works great! If the red light doesn't come on while charging, unplug it & replug it. It works with the Bose headphones QC25. No problem connecting to my phone either. So grateful!

Great especially for the price. Battery lasts a long time and the sound quality seems to be good. Easy to configure and use. My only gripe is that recharging it uses Micro USB-B instead of USB-C and also that the charging port is located in a place that requires removing the bluetooth adapter from the QC25s every time to recharge them. Again, small complaints, especially for the price.

Works great for my Bose QC25 headphones and most importantly, it saves me from having to buy a new bluetooth version of Bose headphones ($$$). It is great to be able to keep the older version of Bose headphones since, when not using this adapter, you have the option to use the aux cord connection to watch in-flight movies on long flights. (As far as I know, the new Bose headphones are strictly bluetooth with no aux cord.) Battery life is great and it charges very quickly. As others have noted, the biggest complaint is that this adapter has to be removed from the headphones to access the charge port for recharging. Otherwise I am very satisfied with this purchase. Since I have bought this adapter, I have used my old Bose headphones more than I ever did before.

Works really well with my Bose headphones. It's as if it's part of the headphones. Great quality, easy to use and pair. I use my old wired Bose phones for cutting the grass (and now listening to tunes while doing it)! Once you get used to where the buttons are, it's easy to turn on/off, volume... I only use for a few hours a week, but can't remember the last time I charged it, so I'm quite happy with the battery life.

The drop in audio quality makes this unusable. Whether listening to music or speech the sound quality is bad. Worse than a $10 pair of earbuds. Having to remove the adapter for charging is not ideal and causes unnecessary wear to the audio jack. It does fit well to the headset and pairs easily, but this was not usable for me.

This works. Connecting the bluetooth is pretty straightforward, and installation is a snap. Volume is a little awkward because it now comes from two places. The charging and battery aspects are a little awkward. In order to change the bluetooth unit, you need to remove it entirely from the QC25. Also worth noting that it does not use USB-C but rather microusb (which is fine - these are older headphones). Sound quality is OK - I've noticed a slight degradation versus wired, but it's definitely not the end of the world. This plus new earpads breathed new life into my QC25 headphones.

If one doesn't want to drop $300+ on the new Bose headphones (prerequisite: you have the wired QC25 and they work well) this buys you 1-2 years of wire free use very economically till you get tempted again with the latest and greatest from Bose. It is light and beautifully merges with the headphones, almost don't notice them. NC is a feature of the headphones and works just as it does when wired. Annoyances: - fit into the aux port is too tight - have to pull hard and almost always send it flying a few feet away - NOT BEING ABLE TO CHARGE WHILE ON THE HEADPHONES IS A SHAME. - charge lasts about 3-4 hrs. should have been better than that - not great for multiple devices for e.g. switching between iPhone and windows dell laptop - I experienced voice drops and quality issues. Eventually I switch off Bluetooth on either device when I am using these and it works fine. Overall product is still worth it for someone like me who has had well maintained QC25 for several years, I am having a better experience with meetings on laptop and watching shows/ hearing music on phone now that its wireless at a fraction of the cost and no noticeable audio quality drop.

Just got this adapter yesterday, for my Bose QC25 wired headset .... this baby rocks !!! Charged it for hour this morning until it was fully charged, slapped it on ( really easy ) , and paired it both with my IPhone 12 Pro Max, and my Sony NW-45 Hi Res audio player. Both synced easily, and I'll tell you, no compromise in sound .... I was very pleasantly surprised . If you have an old pair of wired QC25 headphones that you still would love to use, but don't like the annoying wire, don't hesitate ..... buy this, and you won't be sorry. You can't even tell it's on once you connect, and you can enjoy wireless beauty with your QC25's. I walked 25 -30 feet from both devices to test out the range, once they were connected, and it didn't skip a beat. I'm a satisfied customer !!!

Extremely simple to install providing and amazing bluetooth connection. I was blown away by how fantastic it was. It fits snuggly and you can barely tell that it's there. I would give it more than 5 stars if I could. I was still using the Quiet Comfort 25s and took a punt to see if there was some kind of bluetooth device that I could use with it and bingo, here it is! Further to this, the product arrived 7 days before the expected delivery date - got to love that!

Perfect. Value for money. Removed wires for once and for all.

Uma das melhores compras que fiz na vida. Deu uma sobrevida para o meu fone. Funciona muito bem e a bateria dura muito.

Very good and as expected
