Bluetooth Adapter for Bose QuietComfort 15, Black

Thrilled to bring new life and purpose to my Bose QC2 headphones. Yes, mine have the "notch" on the connector, so there were no issues with fitment. The adapter slips right in and looks like it could be part of the original design. Pairing to two devices was easy, and the controls work as expected. Sound quality is very good for movie and TV viewing. Listening to music warranted tweaking the player app's equalizer, but that, too, yield very good results. I have musical equipment that requires the use of corded headphones, so I need to keep this 10+ year-old Bose set around indefinitely. I just replaced the earpads and now, with this adapter, they've got a lot of life left with much greater functionality.

I don't consider myself an audiophile but I can certain appreciate crisp high quality audio. I do however consider myself a bit of a snob when it comes to brands that make great quality devices. Bose is certainly one such company. I've owned this pair since around 2015 or 2016 but with most headphone jacks in cell phones going the way of the dodo these have been in their case relegated to collecting dust. I was talking with a friend that mentioned some companies have been making Bluetooth adapters to push old tech into the current generation. After a very brief search I found this. My thoughts on this.. Pros Small, sleek, and portable. The device barely adds any extra weight and isn't noticable with long term use. The pair process is quick and straight forward and has been compatible with every device I've tested this on thus far. The audio produced is what I've come to expect from a Bose product. The charge on the Bluetooth piece is a good couple or hours of continuous listening and recharging doesn't seem to take very long. Cons The wired connection to charge this is older micro USB. If you are using your phone and have it your pocket and kneel down the signal will become distorted. The distance you can move from a connected device seems much shorter than today's bt devices. Overall I'm pleased with this piece. It's helped breathe life into an old pair of headphones that would have only seen use on an old ipod or with late night computer use. Works great for outdoor walks, yard work, exercise, or while just trying to enjoy your favorite music without a cord.

An update to my review below. I am ecstatic I purchased this adapter. I use it frequently, it performs perfectly, and I have not experienced any issues. Hopefully your experience will mirror mine. (07/07/2026) I highly recommend this Bluetooth conversion if it fits your Bose wired headset. I have an older pair of the Bose QC2 wired headset. The pads needed replacement and everything else I have is Bluetooth so, I had already put them in the donate pile. Fortunately I saw this attachment advertised so, I replaced the pads and bought this adaptor and I am so very pleased I did. The quality, fit, connectivity, and function is perfect. If you can use it, I highly recommend buying it for your Bose headsets. It works reducing the noise level as well as before if not better, and it simply clicks in place.

Works well to convert your headphones. Sound quality is not a good as the cable. Good battery life and syncs easily to the phone. Designed smartly. Worth the money.

I finally upgraded my iPhone and my old cord to my Quiet Comfort 15 headphones no longer fit my new phone. I could not find a cord that would work. But this Bluetooth adapter works great! The fact that it is cordless is the icing on the cake! Works great!

Wow, I was so happy to find this adapter for my favorite Bose QC15 headphones. I haven't used them in months because the cable was annoying and my phone didn't have a jack anymore. This adapter snapped cleanly into place and blends right in with the original finish. It paired right up and the sound is incredible. One reviewer made a comment about the low volume, I didn't experience that at all, it's as loud as original and I couldn't even crank it up all the way with blasting my ears. I was able to walk around my house with no loss of signal, so great range. The battery has been excellent so far, lasting several hours without a charge yet. Now, if I can find these for my old Bose QC3, I'll be in good shape.

Works Awesome for my QC2 Bose headsets. Has more than enough battery for 10-15 hours of playtime. I have used it for 8 hours straight on a plane with no issues.

I highly recommend this adapter. It is an awesome adapter Q15 Bose headset. It fit exactly as necessary. The quality is fantastic. I saw some post that complained the quality was not great. But I remind them the sound is only as good as the weakest link. That weakest link in this case is Bluetooth technology. In that regard, the quality is just as good as it gets for wireless Bluetooth 5.0 there is available on the market.

Muy buena compra, amarran exacto con este modelo de audífonos Bose. Los compré para mi esposa y está encantada, son de buena calidad y funcionan súper.

Perfect for good old headphones to work with iPhone again

Uses Bluetooth codec APTX and compatible with AAC and SBC. Cannot use any of the high resolution bluetooth codecs however (Aptx-HD, LDAC). Have not used long enough to comment on battery life. Now my QC15 has abilty to use more advanced bluetooth codecs than my QC35.

The BT connection is great! No issues with the sound or distortion. It’s been 3 days so far, very happy with my purchase. Battery performance has been as per manufacturer’s specs.

Excelente en todo, la duración de batería muy muy bien. Me ahorró el tener que comprar otros Bose wireless ya que los teléfonos nuevos solo se conectan vía Bluetooth y esta opción funciona muy bien.
