Sennheiser CX 400BT True Wireless review: New premium earbuds sound great but are a bit chunky

The excellent sounding CX 400BT True Wireless earbuds are a more affordable alternative to the Momentum True Wireless

Curated via Twitter from CNET News’s twitter account….

In my tests on the streets of New York, the wireless connection was pretty much rock solid — the buds are equipped with Bluetooth 5. 1 — and they did a decent job muffling background noise when I was making calls (these have noise reduction but not active noise canceling like the Momentum True Wireless II).

The idea is to sacrifice a bit on the design side but little on the sound side in exchange for a $100 lower list price compared to the Momentum True Wireless II, which earned a CNET Editors’ Choice award.

The excellent sounding CX 400BT True Wireless earbuds are a more affordable alternative to the Momentum True Wireless II.

While I’m not sure the trade-off is really worth it, the quick skinny on the CX 400BT is that they’re excellent sounding but bulbous and arguably not quite as comfortable to wear as the Momentum True Wireless II.

And with a tight seal, these sound great, though not quite as great as the Momentum True Wireless II, which feature the same dynamic 7mm drivers but seem to have a little more bass (it could be that the fit had impact but I just thought the Momentum True Wireless II had a tad bigger, richer sound).

For instance, the case is pretty basic looking — it’s overall more compact than the Momentum True Wireless II’s case — but the hinge feels solid and the top of the case snaps shut with authority (an integrated magnet secures the lid) in place.

The CX 400BT’s case is taller but narrower compared to the Momentum True Wireless II’s case.

In the end, the CX 400BT is a very good set of true wireless earbuds that delivers excellent sound but may just be too big for some people.

In-ear, the CX 400BTs feel more like the original Momentum True Wireless, and over longer listening sessions I found myself adjusting them to take the pressure off certain parts of my ears.

You can do light workouts in these, but unlike the Momentum True Wireless II, they don’t offer any water or sweat-resistance rating; I wouldn’t trust them to stay in my ears for running.

We’ll see how it plays out this holiday season, but these are definitely worth keeping an eye on if superior sound is what you’re after and can’t quite afford the Momentum True Wireless II.

Like some of Sony’s new true wireless earbuds, it appears from the CX 400BT’s build quality that Sennheiser may have a little room to play with pricing.

I do think that in time you’ll see the CX 400BT selling for closer to $150, particularly as we see the Momentum True Wireless II discounted to $250 or less.

Sennheiser didn’t reduce the size of the second-generation Momentum True Wireless II by a lot, but it was just enough for the buds to fit more comfortably.

The original Momentum True Wireless certainly stuck out from your ears noticeably, and the buds were a bit chunky.

While they don’t look or feel as premium as the Momentum True Wireless II, they clearly rise above the level of a budget model.

Sennheiser has a new pair of premium true wireless earbuds and — surprisingly — they’re not called Momentums.
