It’s a terrible day for reviewer when she has no complaints. But that’s the situation I find myself in with these earbuds. (Actually, perhaps I would have preferred more present low-mids. Phew). A meaty sound signature with solid resolution and detail, there’s no question that the CX 150BT is a classically Sennheiser in character. And it has a lot of similarities to the much higher priced HD 1 Free. Add to that great call quality and relatively long battery life, and you’ve got a great bang for your buck for $80.

Sennheiser’s CX 150BT score points with a balanced, natural sound that offers precise bass with depth and very clear voice reproduction, making these Bluetooth-in-ears ideal for movies and spoken-word content. The only real criticism is the existence of cable noise, but otherwise these lightweight headphones impressed us with their long battery life, stable wireless connection and the option of multi-pairing for connecting two devices simultaneously.

The Sennheiser CX 150BT is a great-sounding pair of wireless earphones under 5K that is marred by the absence of some integral features and some build flaws. If you don’t mind the absence of voice assistant support and an IP rating, and if you deem the design to be good enough for you, there aren’t too many wireless earphones in this price range that sound as good as the Sennheiser CX 150BT. However, if you’re a basshead, you’d have to look elsewhere to satiate your bass needs.
