Sennheiser CX 400BT

Sennheiser’s first true wireless headphones outside the Momentum range offer the same superb sound quality without such a steep price tag.

The Sennheiser CX 400BT True Wireless earbuds have an understated design but pack 7mm full range dynamic drivers for the detailed and wide sound that belies its modest looks. Add in a light build and comfy ear tips for comfortable extended wear when working from home or on the go and you have an ideal, high performing pair of earbuds suited for the new normal.

The Sennheiser CX 400BT true wireless earphones are a good way to experience quality Sennheiser earbud sound without the price tag of the Momentum 2 earphones.

Sennheiser's CX 400BT True Wireless retain so much of what makes the company's sound great, and come at a price that, while still a little high, is far better than its previous models. You do lose out on some features and performance, but if sound is what you're after, these won't disappoint.

They’re not the most glamorous nor the most distinctive – but Sennheiser’s new CX400BT true wireless earbuds have it where it counts. They sound open and articulate, and if there’s detail in a recording to be extracted, you can rely on them to do just that.

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. Other models like the Jabra Elite 75t and Elite 75t Active may not deliver quite as good sound, but they cost a little less and fit better. 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.

The Sennheiser CX 400BT wireless earphones offer remarkable quality and tremendous value in one attractive package. They are a standout choice at this price.

If you can live without noise cancelling, and the CX 400BTs prove to be anywhere near as sonically-capable as their pricier siblings, they might just give Apple's AirPods a run for their money.
