Great product with a small quirk

They work great for the most part. The sound quality increases is noticeable. The one issue i have is small with them is with the momentum 5’s the on head detection is doesn’t work properly when using this dongle as it pauses the track only after i put the headphones back on (Yes using the latest firmware). Otherwise I definitely recommend spending the extra money on this.
I would recommend this to a friend!

Sounds great, but is a pain in the butt

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.
No, I would not recommend this to a friend.

Solid audio enhancement

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 would recommend this to a friend!

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