Review on Sennheiser CX 350BT Black - Bluetooth 5.0 Wireless Headphones with 10-Hour Battery Life, USB-C Fast Charging, Virtual Assistant Button, Two Device Connectivity by Agata Koacz ᠌

As everyone writes, it’s not very comfortable to wear, but for me it’s not critical, you can get used to it. As for the sound, (I compare with Jbl E25bt) yes, the sound quality is excellent, but there is not enough volume, Jbl sound louder. I love rock, and when there are deep basses, I really want to add sound, but no luck. The battery holds about 15-17 hours, it all depends on the volume. Bluetooth catches just fine. In general, the product is satisfied. when I tested the sound, I thought I was already deaf, but three people confirmed to me that the volume was not enough))
