Sennheiser CX 400BT review: Great-sounding mid-range wireless earbuds


With its third set of true wireless earbuds, Sennheiser's CX 400BT is a more affordable option. The company manages to mostly retain the stellar sound quality from the Momentum True Wireless 2 along with customizable and reliable touch controls....

Great sound ; Customizable controls ; Configurable EQ

No ANC ; No ambient sound ; No automatic pausing ; No wireless charging

Sennheiser CX 400BT Review


Excellent audio performance with rich bass depth and detailed highs ; Comprehensive, intuitive, and customizable on-ear controls ; App features adjustable EQ ; Secure fit

Pricey ; Not ideal for gym use

The Sennheiser CX 400BT earphones deliver some of the best on-ear controls and audio performance you'll find in a true wireless pair.

Sennheiser CX 400BT True Wireless Review


The Sennheiser CX 400BT True Wireless are sleek in-ears that resemble the Sennheiser MOMENTUM True Wireless 2 in look and performance. They have a similarly warm...

Decent recording quality. Graphic EQ available. Stable in-ear fit. Great build quality.

Disappointing battery performance. Bulky design.

The Sennheiser CX 400BT are alright for mixed use. They're fairly comfortable and are stable enough for moderate exercise. They can also reduce quite a bit of mid-range sounds like ambient chatter at work. However, they struggle to block out bass-range...

Sennheiser CX 400BT review


The Sennheiser CX 400BT are a rich-sounding set of wireless earbuds that make up for their lack of noise cancelling with a deep toolbox of other features.

Great sound ; Good app and features ; Respectable battery life ; Comfortable fit

No ANC ; No water or sweat resistance

And, while not every one of the many bonus features entirely works, it’s great to see so many tools and customization possibilities stuffed into a tiny pair of wireless headphones. Wait for the AirPods 3 if you really want, but if you can live without...

Sennheiser CX 400BT True Wireless review


Sennheiser finally engages with the true wireless earbuds mainstream – with fairly predictable results.

Widescreen, detailed, and quite upfront sound More comfortable to wear than they look Great app and good touch-control

Can be excitable with treble sounds Ordinary battery life Don’t quite look or feel the asking price

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...

Sennheiser CX 400BT Review


In a world of convenient but pricey Apple AirPods and remarkable sound quality from Sony and Bose, it can be hard to stand out. With the Sennheiser CX 400BT, it's about value. Sennheiser brings quality across the board to a reasonable price with these...

– Comfortable fit, simple design and impressive sound

– Not the loudest and battery life could be better

The Sennheiser CX400 BT wireless earbuds are an ideal pick for audiophiles who don’t want to go beyond the £200 mark. The quality sound and basic design provide a delightful, no fuss audio experience. However, there’s more features and better battery...

Sennheiser CX 400BT True Wireless review: Enjoy excellent audio for less


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

Superb sound quality ; Stable connection ; Quick, seamless pairing

No splash proofing ; No ANC ; Not cheap

Sennheiser CX 400BT Review


Read the in depth Review of Sennheiser CX 400BT Audio Video. Know detailed info about Sennheiser CX 400BT configuration, design and performance quality along with pros & cons, Digit rating, verdict based on user opinions/feedback.

Stellar sound quality ; Customisable touch controls ; Comfortable and secure fit ; Customisable EQ

Slightly harsh highs ; Bland design ; Lacks features for the asking price

The Sennheiser CX 400BT features stellar sound quality and customisable touch controls and EQ, but not much else. Priced at Rs 16,990, the earphones face fierce competition from competitors that provide ANC, Ambient Sound, wearing detection, and/or...
