Reviewers from ndtv have found the following[***]:
The Sennheiser CX 400BT is a true wireless headset aimed at purists who look for good sound above everything else. Priced at Rs 16,990, it comes with most of what makes the Momentum True Wireless 2 so great, minus one big feature – active noise cancellation. The earpieces are quite large, and stuck out of my ears considerably; while this didn't affect fit and comfort too much when using the right ear tips, it definitely looked a bit odd. Sound quality was largely on par with the current top picks for true wireless earphones.

Sennheiser's CX 400BT True Wireless earbuds are big and boxy. They are comfortable to wear, but you need to get the tips far enough into your ear canals to create a really good seal. The controls on the CX400BT might just be the best touch controls I've ever used. But the $200 Sony W800Nuds can deliver 13 hours with active noise cancellation.
Reviewers from pcmag have found the following[***]:
The Sennheiser CX 400BT are a more affordable version of the $300 Momentum True Wireless 2. The earpieces are compact and use only an eartip to keep them in place. The left and right earpieces have touch-sensitive panels that divide the controls up in a sensible manner.
Reviewers from rtings have found the following[***]:
The Sennheiser CX 400BT True Wireless are sleek in-ears that resemble the MOMENTUM True Wireless 2 in look and performance. While their warm sound may not be perfect for neutral sound, they have a graphic EQ via their companion app. These headphones are alright for mixed use but not suitable for wireless gaming due to their high audio latency when connected to Bluetooth-enabled PCs.
Reviewers from t3 have found the following[***]:
The Sennhesier CX400BT are on sale from September 15th, priced at £169. Both the earbuds themselves (at 6g each) and the charging case (37g) are reasonably weighty. Wireless connectivity is via Bluetooth 5.1, and there's support for SBC, AAC and aptX. Voice assistance can be provided by either Siri or Google Assistant.
Reviewers from techradar have found the following[***]:
The Sennheiser CX400BT are a high-end true wireless earbud. They share the same 7mm full-range dynamic driver as their more expensive Momentum True Wireless 2 siblings. Despite a 6g-per-earbud weight they prove comfortable even over extended periods. A total of 20 hours' battery life is by no means a disaster, but it puts them at a mild disadvantage compared to any number of nominal rivals.
Reviewers from trustedreviews have found the following[***]:
The Sennheiser CX 400BT are the latest earbuds from the venerable German audio brand. They sit beneath the award-winning MOMENTUM TW2. Bluetooth 5.1 is the wireless connection and despite the premium sound claims there's no support for LDAC or aptX-HD. Battery life delivers 6.5 hours, with the charging case providing another two charges for twenty hours in total.
Reviewers from whathifi have found the following[***]:
Sennheiser's CX 400BT are some of the best-value budget earbuds we've come across. They lack active noise-cancelling, smart pause functionality and IPX4 splash resistance. They do support Bluetooth 5.1 support and mobile app features, though – neither of which is a given at this level.
