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

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.

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!

I'm pretty used to Bluetooth headphones sounding like mud. The aptX sound quality on this was a noticeable improvement over previous adapters I've used. It fits well on the QC25s and looks appropriate, and makes a worthwhile upgrade for these headphones. There are some mechanical design issues that could use improvement. It's difficult to distinguish the buttons by touch, you have start from the bottom and count one-two-three. Makes it hard when you want to quickly reach the play/pause button. This would be improved if they made the play-pause button stick out more to provide a landmark. Another awkward feature is the USB port, it's located so that it can't be charged while the adapter is connected to the headphones, so you have to remove the adapter each time it needs charging.

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.

Bought this to watch my LG TV and not disturb my wife. It pairs but then looses the connections with the TV. Every mring I go through teh same routine of turning teh TV and unit on and off, deleting the device, repairing and maybe 25% of the time I am successful. I give up and am returning it. Its a great idea and a way to avoid paying $200 for a new set of Bose headphones but it just did not work for me. The seller provided only online support with FAQ. No real help

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 !!!

PRO: -Audio is good when it connects correctly. I was able to successfully get aptX and ACC codecs to stream from my iMac and ACC codec from iPhone. -Physically seats well to the QC25. -Reconnecting to paired devices after turning off and back on is instant. -Price is great. -Can connect simultaneously to two iPhones (6 and 8- Bluetooth v4.2 and 5.0) CONS: [there's a lot] -mic is sub par. On the iphones, coworkers complained of not being able to hear me very well. -Why they block the usb charging port, so that you need to remove it from the headset to charge is a mystery and a pain. -The buttons are close together and don't have unique discernible tactile markings, so it's difficult to use without looking at them. After a little bit of usage you know what they do and you can figure it out, but a raised bump on the play button would have been nice. -Pairing two devices is not intuitive- read the instructions! -When this connects with SBC codec the audio is TERRIBLE. Sounds like a tin can. Mic is equally awful. This only happened when connecting to my iMac and Macbook Air, and only when actively using the Mic. When just streaming audio only, it reverts to ACC codec and sounds great. -Because Apple downgrades the codec to SBC when the Mic is active (in both Bluetooth 4.0 and 5.0, in my testing) and this device is so terrible with that codec, this is not useable for conference calls, webex, zoom, etc. I still use it, but have to switch the Mac to use the internal mic on the Mac, and then just listen on the headset. This means I can't get up to walk and talk, which isn't a problem when using the web cam but on audio only calls from my computer this is a shortcoming, as I sometimes like to get up to pace/talk.

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.

El producto funciona correctamente y la conexión a un dispositivo bluetooth fue fácil. El problema que veo, que es muy importante, es que el puerto para cargar el dispositivo queda bloqueado al estar conectado a los audifonos. Esto significa que, cada vez que se necesite cargar, habrá que desconectarlo de los audifonos. Esto, con el tiempo, podrá probocar un desgaste y falla en el puerto de audio de los audifonos.

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

Great product and service

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
