Sennheiser’s $200 CX 400BT earbuds make its top-notch sound more affordable

We’re big Sennheiser fans here at Digital Trends, so it’s great to see that the renowned audio company is lowering the price you need to spend to get a set of its true wireless earbuds. The new CX 400BT launched today for $200 and will be available in stores and online on September 15.

Sennheiser CX 400BT

Available in black or white, the CX 400BT sport the same 7mm drivers that Sennheiser used in the $300 Momentum True Wireless 2, which ought to give them excellent sound quality. In fact, we rated the Momentum True Wireless 2 as having the best sound of any true wireless earbuds we’ve reviewed.

Our only complaint with that model was their price and their bulk. While the CX 400BT don’t look any sleeker than their siblings, they’re considerably less expensive.

For the lower price of $200, you’re still getting seven hours of battery life per charge, but the maximum playtime when you include their charging case capacity is 20 hours vs. the Momentum’s 27 hours. The touch controls are customizable via the Sennheiser Smart Control app and give you access to either Siri or Google Assistant.

Unlike the Momentum, the CX 400BT do not offer active noise cancellation (ANC) and there’s no mention of a hear-through mode for piping in outside sounds. There is background noise cancellation for phone calls, however, according to Sennheiser’s press release.

There’s also no mention of an IP rating for dust or water resistance, but we’re guessing they can probably withstand some sweat if you intend to use them at the gym.

With support for aptX as well as AAC and SBC codecs, we’re hopeful these new, more affordable true wireless earbuds live up to the Momentum True Wireless 2 in terms of sound quality.

We’ll let you know as soon as we get them in for a review.

Sennheiser Momentum True Wireless 2 vs. Sony WF-1000XM3: ANC earbuds shootout

Ever since Sony launched the WF-1000XM3 true wireless earbuds in 2019, they've been the "buds to beat" in almost every sense. With killer sound, battery life, and active noise cancellation, there is very little these earbuds don't get right.

But personal audio tech -- especially in the true wireless category -- is on hyperdrive right now, and even the best don't get to stay at the top for long. So now that Sennheiser has released an ANC-equipped second version of its pricey-yet-powerful Momentum True Wireless earbuds, the question is: Has Sony met its match?

Though it won't come as much of a surprise to those who follow the true wireless earbuds space, a Federal Communications Commission (FCC) document confirms that Sennheiser's follow-up to its superb Momentum true wireless earbuds will be called the Momentum 2, and they'll come with active noise-canceling (ANC) built-in.

It wasn't hard to come to this conclusion. The FCC document is comprised of two pages from Sennheiser's user manual for the Momentum 2, the follow-up to the company's impressive Momentum True Wireless earbuds. Page 2 indicates how to use the touch controls for the earbuds, and the smoking gun is the ANC feature that you apparently toggle on and off with a triple-tap on the right earbud.
