Before we go further, I want to let you know that, we used Xiaomi Mi A1, Google Pixel 2 and Huawei Nova 3i for testing this earphone. Although there is not much of difference in sound quality, the earphones remain same.

The Hong-Kong-based audio specialist’ Zeta IEM earphones comes with an average packing, nothing fancy. The tiny translucent pouch contains velcro strap, a handy shirt clip, three pairs of differently-sized silicone tips (small, medium or large) along with two red rubber earbud housing loops.

Even though the unboxing experience is meh, but the included things like the velcro (used for hassle-free carrying the earphone around) and the two red earbud housing which can be used for sporty looks made up the impression that was lost.

Brainwavz Zeta IEM Earphones: Design And Build Quality

We can’t deny that the build quality isn’t good or say probably not best of what you’re paying for. The driver unit is cylindrical, however, the ear tips are angled inwards for a better fit. Adding the add-on wingtip, keep the Zeta locked in your ears, which also adds slight noise isolation too.

The earphone itself is plastic built, which makes it lightweight and exceptionally comfortable earphone to wear. The in-line controller has a rounded design with a chunky button. Not just that, the 3.5mm connector is thumped inwards, which not a fan of. Well, the overall design and build quality aren’t great.

Brainwavz Zeta IEM Earphones: Sound Quality

This earphone is remarkably comfortable to wear, thanks to its tilted ear tips. This earphone seals your ear canals. Coming to the quality, the lows, mids, and highs were good, although, the highs were leaking sometimes. The vocals sounded natural and extensively satisfying.

The inline control works well and has a single press, double press and triple-press options to play/pause, fast forward or rewind. A long press will pop up your voice assistant. The voice quality through inline mic is quite good (not the best) and in outdoors, but considering the price it is decent. Not to forget, it does (to some extent) provide good noise isolation.

  • Lightweight
  • Good sound production
  • Varied accessories included


  • Unboxing experience could’ve been better
  • Build could have been better
  • In-line controls are on the left side


This earphone was tested over a period of four weeks, so the conclusion is clearly appropriate. The Brainwavz Zeta IEM earphone is by far one of the lightweight earphones I’ve ever used. And thanks to its tilted ear tips, it fits in perfectly. The audio quality is quite good considering the price, although the build is below average.

So, if you are looking for a good sounding earphone under Rs 1000 budget, you can’t possibly go wrong with this, but then again, durability is parameter too, so do keep that in mind before going for this one (below is the overall points in different parameters, do check). This is priced at Rs 999 at the time of writing.
