    Must have for hi-res bluetooth audio

    I have both sennheiser momentum 4 wireless headphones and momentum 4 True Wireless ear buds, they both sound good. Once I got this, it totally changed my listening experience. Most people say they can't tell 16-bit/44.1khz CD quality from 32-bit/96khz. I bet you can when using this dongle. I listened using my phones (Galaxy S21 ultra) bluetooth and the sound is good, a little flat and a little lifeless, but I don't expect much from bluetooth. When I plugged this in, the depth and fullness of the music suddenly appeared, along with more "volume." While it does sound louder, I believe that is due to bypassing the phone's internal bluetooth and having a different gain stage. It allows me to benefit from aptx adaptive, which is pretty dope. If you have aptx lossless or adaptive headphones, this is worth it. I am very happy with this product.

    Excellent

    Outstanding Bluetooth Adapter. I was crushed when I lost it. My suggestion when you have it in use, put some type of clear or cloth bag. If you accidentally bump the adapter it could fall off unbeknowing to you. I can tell the difference of the upscaling of the different codecs. Nice using with an iPhone which only has the AAC Codec

    Worth the sound upgrade. Noticeably better sound quality and sound stage separation.

    Great addition for any PC/Iphone

    I bought this to compare with the Creative BTW6 and am glad to report it functions wonderfully out of the box. Item connects seamlessly with all my bluetooth devices and has no 2 second audio loss/delay when starting a new track as the BTW6 does. Though it does lack LDAC codec, aptx adaptive works beautifully.

    Aptx lossless

    Want APTX lossless with the GUARANTEE that you are getting lossless and not just aptx adaptive? This has a windows app which let's you choose the lossless option. It has a purple light that tells you it is connected via aptx lossless. I use it in many applications. You can even force it to do lossless using software by resampling all audio to 44.1 khz/16 bit.

Feel all the emotion of your music. MOMENTUM 5 Wireless combines our best-ever noise cancellation with brilliant, exceptionally detailed sound. Advanced codecs and a meticulously tuned driver make instruments feel like they’re right there, playing just for you. The new ANC uses twice as many microphones (8) for three times better midrange noise cancellation than MOMENTUM 4 Wireless. The (replaceable) battery provides up to 57 hours of playtime with ANC on. You also get clear calls, gaming mode, and Bluetooth 6.0*. But features don’t define MOMENTUM 5. It’s how effortlessly they disappear, leaving nothing behind but emotion and music.
