Sennheiser Bluetooth USB донгл BTD 700

The difference in sound quality and detail is amazing, but it's so physically sensitive that it doesn't make much sense out in the world. All I have to do is touch the dongle and it disconnects. Also, I have to turn off my iphones's Bluetooth or my Momentum 4 TW will connect to that instead. But if I want to use the Sennheiser Smart Control APP, I have to disconnect from the dongle and reconnect to the iPhone; make any technical adjustments; then disconnect from the phone and reconnect the dongle. Also, I had to buy a wireless charger for my iphone because I can't charge the iPhone via the usb-c port while using the dongle. The short version is that this dongle makes lossless listening possible via Bluetooth, which is terrific, but it's not practical out in the world. If they were able to make it less physically fragile and/or make it compatible with the Smart Control App and/or give it its own app, I would give it 5 stars. It's still worth it to get the signature Sennheiser sound through Bluetooth, but I won't purchase it again when it eventually snaps off in a pocket one of these days.

The BTD 700 pairs well with my Galaxy S24 Ultra. It functions as expected, providing an enhanced sound experience. While there's a slight reduction in volume, the improved audio quality is a worthwhile trade-off. It's a solid option for those seeking better audio.

I've been using one of these for about a week now with my Sennheiser MTW4 earphones and Google Pixel 8 Pro and I've been very happy with it. The improvement in sound quality going from regular APTX to APTX Lossless, when streaming via QOBUZ, was easily noticeable. Feels well made and was easy to set-up. Would recommend to anyone looking for a relatively cheap way to improve sound quality.

I used it with Sennheiser Momentum 4 TWS. It's just elevated the sound.
