In the higher price range, Sennheiser probably makes the best sounding wireless earbuds on the market – the HD 1 Free, which is based on the famous wired Momentum. Their true wireless Momentum is also a winner. But their cheaper wireless earbuds I was never a huge fan of. However, the CX 150BT has changed my mind about what the company can produce under 100 bucks. At $80, what can we expect from Sennheiser’s latest release? Let’s find out in this Sennheiser CX 150BT Wireless Review.
Sennheiser CX 150BT Wireless Review
IN the BOX
I dig the no bull-$%^*, minimalist design of these earbuds. They easily pop into the ears and create a snug seal with great sound isolation. You’ll also have a few different sized eartips to choose from. So, you shouldn’t run into any problems here.
Controls and Functionality
You’ll get all of the usual functionality using the three buttons on the remote – play/pause, track-skipping, volume control and call answering/ending/rejecting. There’s also a mute feature for calls.
The CX 150BT offers 10 hours of total battery life. This is on the higher end of standard for a pair of wireless earbuds. Audio-Technica’s latest wireless buds – the CKR300BT – for example, only offer 8 hours. That being said, the CX 150BT is 20 bucks more expensive. So, you get what you pay for.
Great call clarity. The caller came through clearly (no muffled sound) and the mic had good sensitivity as well.
Bluetooth and Supported Codecs
The CX 150BT supports Bluetooth 5 (the latest Bluetooth version) and AAC, for iPhone and Android.
Sennheiser’s wireless models are advertised as coming with the Sennheiser Smart Control App. On more expensive models, the app gives you added control over your headphones. But when I paired the CX 150BT to the app, it didn’t offer any added features, such as equalizer control. So, with respect to this model, I’m not too sure what the point of the app is other than giving some brief guidance on how the remote control works.
Deep and powerful with some decent grip, this is the kind of bass that reminds of me of Sennhesier’s higher priced model, the Momentum. Listening to pop, the low end is thick and punchy, while rock tracks offer tons of warmth and bass oomph. Strings reveal a solid level of substance and timbre. And the richness of the low end lends a grand and majestic flavor to classical music in general.
The bass is so powerful that it tends to overshadow the lower-mid frequencies. So, at times, you may feel like part of the mix is missing. But the upper mids avoid too much emphasis and you will still get a relatively full-bodied sound when listening to rock and pop-rock tracks. And especially as you reach the higher frequencies, the sound becomes quite clean without losing that voluptuous profile. Which is again, very Momentum-like. And if you like a sumptuous feel, then the CX 150BT will certainly deliver.
Sennheiser hit the sweet spot up here. There’s enough snap here to do justice to funky tracks. But it avoids becoming too sparkly or fatiguing. And that satiating weighty feel is still present in this range. Now, usually, with this kind of sound profile, female vocals lose that nice airy feel. But the CX 150BT keeps vocals velvety and rich without losing too much buoyancy.
Not bad at all. Although the soundstage doesn’t feel incredibly vast, the sense of dimension is certainly there. And you won’t just feel width and height, but you’ll also get a perception of depth and hear clear gradations along that axis.
PROS and CONS
Pros: Rich and satisfying Sennheisery sound signature; good call clarity, solid battery life.
Cons: Not suitable for those who like a lighter sound profile with a leaner bass.
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.
