Muswor Bluetooth Receiver Adapter Wireless Converter for Bose QuietComfort 25 Headphones (QC25) with 2.5mm Connector, Built-in Headphone Amplifier

THE COMPANY SENT ME A NEW UNIT AND IT WORKS LIKE A CHARM....THANK YOU. This is a follow up to the review below...the company contacted me and offered to resolve this issue. I didnt reach out to them— they reached out to me— i call that good customer service....anyone who stands by a product and resolves issues like this in a timely is someone to do buisness with. I will post and updated review after the better fitting unit arrives...like i said i liked the quality of the unit except the loose connection..if that is resolved it would be well woth the money to make your wired headseat wireless.It works..connects well to blue tooth and sounds good....the downfall is that it fits sloppy in the jack (way to loose)— it has fallen put while walking—it they can solve that issue it would be a a good product

I had previously paid ONE HUNDRED DOLLARS for one prior to bose releasing a Bluetooth model and it broke in a month or so.This guy has great battery life.Long-distance, can walk pretty far away from my device (like the restroom) and still have a connection.The mic works GREAT.The sound quality is just fine.Totally suggest this. The older Bose is JUST as good as the newer ones, and I'll never have to worry about the lithium Ion battery dying. I imagine it'll work well for other headsets too. (I actually used this for work! Although the battery life is going out on me, I've used the heck out of it. 100% worth the price, I'll be getting another soon.Still can't believe I paid $100 for that other one. (2016 I think?)

Though the dongle fits fine and the phone calls are getting through fine (that's what i been told), even cranking the sound on my OnePlus 5T to the max doesn't cut it. It sound too low. I don't recommend the product at all. I even considering getting back to cable!Update: The dongle stop working out of the blue. Doesn't hold charge anymore, after two month of limited use (when i say limited i mean 10 times at the most). This is a terrible device!

defect: I don't think it has a auto-stop charging mechanism built in because I left mine a little too long and it heated up and if i didn't come back and touch it seems like it could have caught fire. It was pretty hot. And all i did was leave it plugged in for like an hour or so. When it worked it was ok.

Sounds great, easy to operate, great battery life Absolutely love this adapter! Really surprised out how incredibly it sounds, no distortion, clean and crisp, the bass boost feature is awesome, the built in amp should be designed in a very professional way, better sound quality than using with cable. The battery life is great too, it is working more than 8 hours now! Easy to operate, nice build quality and Bluetooth range is about 30 feet. Really happy with this purchase!

Took it out of the package, gave it a charge, followed the easy directions and it works great. It paired with my iPhone and plugged into my Bose QC25, wireless headphones! Can't rate the battery life, just got it.

They work good for the price. They do have a electrical hissing sound as soon as they connect.

I was initially skeptical, but this works just as advertised. Connects easily and sounds great at half the cost of similar devices. Charge has lasted me on at least medium range airline trips (3-4 hours). Would buy it again in a heartbeat.
