Sennheiser CX 120BT review: Good Audio quality, minimilastic design and great battery!

Sennheiser earphone

Recently the trend of audio accessory has gained momentum, and all the companies and brands in the market are racing to launch affordable truly wireless earphones and while there is a huge list of brands, there is one that everyone knows.

The German audio brand, Sennheiser, is one of the top players in the global market right now, and the company has a portfolio of truly wireless earphones. Recently the company launched the CX 120BT wireless earphones at Rs 3,490, and today we take a look at it.

Body and Design

While just like other wireless earphones, the CX 120BT comes with a minimalistic design and a glossy finish at the end of the earbuds. The earphones look very good, and very light to carry, you can easily let rest on your shoulders while you are not using it, you don’t even feel any weight. But we do wished the end of the earbuds came with the magnetic clasp that helps in attaching both the ends, but it is fine.
The wire that connects both ends of the earbuds feels a little short, and the back of the earphones where the wire is attached, that area can feel a little uncomfortable. The earphones come with in-line controls that consist of a power/action button and volume +/- keys. The keys are well-spaced out and are big enough to avoid accidental presses. The same three buttons can also be used to skip or fast forward a song, accept/reject or mute a call and so on. Adjacent to the controls is the USB Type-C port that can be used for charging.
The buds of the earphones are also very comfortable and fit perfectly.


Let’s talk about the battery! The company claims that the earphones can go on to six days with a single full charge, but it also depends on how much you use it. I used it for almost the whole day and the earphones discharged after 3 days. So not bad, but not at par with the expectations of the company.

Also, when you are not using the earphones it automatically switches off to save battery which is a good feature, but at times it can get a little frustrating too. The earphones take almost 1.5 hours to charge fully. But with that amount of usage, the battery is a thumbs up.

Audio Quality

The CX 120BT features SBC and aptX codecs, as well as aptX Low Latency. In terms of connectivity it comes with Bluetooth 4.1 which enables connection with two devices simultaneously. If we talk about the quality of the audio, just like other products from the company this one is no exception. The audio quality is great, but it gives you a little too extra bass, and vocals are also average, and a humming noise in the background will irritate to you a little. But if you are not looking for the perfect wireless earphones under 3K, than the Sennheiser CX 120BT is recommended.
Also there is no latency, but it sometimes gives you glitches in between, don’t know why!


The Sennheiser CX 120BT comes with good audio quality and a battery system. It is a great-sounding pair of wireless earphones under 4K that is missing out on some features, but that’s ok!

If you don’t mind the glitches in between your playtime sometimes and ask for some extra features then you can go for this one, as there aren’t too many wireless earphones in this price range that sound as good as the Sennheiser CX 120BT. However, if you’re a bass-head, you’d have to look elsewhere to satiate your bass needs.
