Sennheiser released the Momentum Legitimate Wireless 2 earphones previously this yr, which, whilst great when it arrives to audio good quality and features, are unquestionably on the high priced facet at Rs. 24,990. A significant explanation for the large value is lively sound cancellation when this aspect does contribute to the exceptional total practical experience, it also puts the earphones out of access for numerous buyers.

Priced at Rs 16,990, the Sennheiser CX 400BT comes with most of what will make the Momentum Legitimate Wi-fi 2 so good, minus a single major aspect – active sounds cancellation.

Is this now the most effective pair of accurate wi-fi earphones for less than Rs. 20,000? Come across out in our critique.
Whilst massive and odd-seeking in the ears, the Sennheiser CX 400BT is a at ease accurate wireless headset
Quality make top quality, but the Sennheiser CX 400BT earphones are big
Only the third pair of accurate wi-fi earphones released by Sennheiser in India, the CX 400BT is a bit far more inexpensive than the high quality Momentum Accurate Wireless 2 earphones. The large big difference here is the deficiency of energetic sound cancellation, but the CX 400BT is a mostly related headset in all other ways, which include style and design, develop high quality, and technical specs.
The Sennheiser CX 400BT’s earpieces search somewhat similar to the Momentum Genuine Wireless 2 equivalents, with massive strong plastic casings and a massive Sennheiser symbol on the outer facet of just about every, which doubles up as a touch command panel. The earpieces are very significant, and stuck out of my ears noticeably even though this did not have an impact on in shape and comfort much too considerably when applying the suitable ear tips, it absolutely appeared a little bit odd. Also worth mentioning is that there is no formal water resistance ranking on the Sennheiser CX 400BT, which is pretty disappointing for the selling price.
Touch controls on the Sennheiser CX 400BT are rather easy to use, and go over all of the core functions, which includes playback, phone handling, volume, and voice assistant obtain. You can customise these controls as a result of the Sennheiser Good Control application, as perfectly as alter equaliser configurations and update the firmware of the headset. While simple and not genuinely wanted for substantially beyond the original set up, the app’s capability to customise the touch controls could occur in useful.
The charging scenario of the Sennheiser CX 400BT isn’t as well extravagant, but it just isn’t far too essential possibly. It has an everyday plastic finish that matches the earpieces, and a magnetic lid that retains it securely shut. There’s a USB Variety-C port for charging. This scenario is additional practical than stylish, but that’s not a poor detail. It is just not far too significant, and in shape quite effortlessly in my pocket. Every single earbud weighs 6g, although the circumstance weighs a realistic 37g.
Qualcomm aptX assistance will make these among the best sounding true wireless earphones you can buy
For connectivity, the Sennheiser CX 400BT employs Bluetooth 5.1, with aid for the SBC, AAC, and Qualcomm aptX Bluetooth codecs. The earphones use 7mm dynamic drivers and have a frequency response selection of 5-21,000Hz all of these specifications match individuals of the Momentum Correct Wireless 2 earphones, with the noticeable exception of lively sounds cancellation.
The earphones ran for all-around 6 hrs per cost at reasonable to superior volume levels, with the charging situation giving one more two whole fees to the earpieces, for a whole battery daily life of about 18 several hours per charge cycle. Though the range of extra rates you can get from the circumstance is just not remarkable, the battery life of the earpieces is rather fantastic in contrast to other selections in this price segment.
Excellent seem top quality on the Sennheiser CX 400BT
I’ve practically normally identified that advanced Bluetooth codec guidance goes hand-in-hand with very good seem good quality, and the Sennheiser CX 400BT supports that inference. The Qualcomm aptX codec helps make a recognizable distinction to audio quality, and the Sennheiser CX 400BT sounded wonderful when utilised with an Android smartphone that was able to activate the codec. Seem high quality was largely on par with that of the Sennheiser Momentum Correct Wi-fi 2, which is my existing major choose for musicality between genuine wireless earphones.
I employed the Sennheiser CX 400BT with an Android smartphone for much of this evaluate, but also examined it with my MacBook Air and an iPad mini for reference. Although I are inclined to use Spotify for day to day listening, I discovered myself favouring Tidal’s superior-resolution streaming while applying the Sennheiser CX 400BT, thanks to the mix of good driver tuning and specialized functionality.
Although the CX 400BT sounded wonderful with any form of songs and at all volumes, using significant-resolution tracks and turning the quantity up to about 90 percent brought out the absolute best in these earphones. Listening to Bruno Mars’ Chunky and Ain’t No Mountain Substantial Enough by Marvin Gaye on Tidal Masters was an amazingly satisfying knowledge, with the earphones bringing out oodles of depth in the tracks. Even the faintest factors in the beat of Chunky felt serious and existing, while Gaye’s voice sounded clean up and total of character.
Battery lifetime is good, with close to six several hours of listening for each charge on the earpieces
Like the Momentum Legitimate Wireless 2, the Sennheiser CX 400BT’s sonic signature certainly has some flavour to it, and just isn’t as balanced or flat as what you’d get with some other choices these types of as the Lypertek Tevi. As an alternative, you get punchy lows that seriously drive up the energy degree, all even though remaining refined and managed more than enough to not audio much too boomy.
Even though the aptX Bluetooth codec assisted convey out detail and refinement in substantial-resolution audio, this did not essentially indicate that compressed audio sounded lousy. The Sennheiser CX 400BT sounded a small extra aggressive and forceful with Spotify and YouTube Music, but by no means uncomfortable. The earphones’ adaptable nature also meant that very much any style sounded excellent, while the bias to the lows made for more entertaining seem with quickly-paced electronic audio tracks.
Listening to Inside My Head (Aeroplane Remix) by Riton, the audio was engaging and immersive, with the very low-conclusion for me being felt extra than heard. The mid-assortment and highs ended up also cleanse and very purely natural, but the total sonic signature was seriously defined by the reduced-end drive. Whilst a good deal of listeners might like a a lot more purely natural-sounding pair of earphones, this sprint of flavour and character is what designed the Sennheiser CX 400BT all the more endearing to me.
The earphones did also get the job done effectively ample for basic audio, together with watching video clips and voice phone calls. Quality options from Sony, Apple, and Jabra are a bit much better for voice calls, but the Sennheiser CX 400BT does a reasonable work, with satisfactory audio on both of those finishes of the contact. The absence of options these kinds of as active or environmental noise cancellation are the differentiating element right here, with the Sennheiser CX 400BT becoming additional focused on tunes.
Verdict
Sennheiser’s existence in the premium genuine wireless house has so much been minimal to the flagship Momentum Genuine Wireless vary, so the CX 400BT comes as a welcome addition to the sub-Rs. 20,000 price tag section. With mostly the same effectiveness as the Momentum Accurate Wireless 2 when it arrives to sound high quality and battery lifetime, this is a worthwhile headset to look at, assuming you do not want lively sound cancellation.
The most musical of all the correct wi-fi earphones I’ve reviewed in this value section, the Sennheiser CX 400BT is best for customers who worth seem top quality and effectiveness with songs higher than all else. If you want lively sound cancellation at around this cost, choices this kind of as the Jabra Elite 75t and Sony WF-1000XM3 are also worthy of looking at.
