  • The Infinix Quiet X has an MRP of Rs 8,999, but is available online for around Rs 5,000.

  • The headset has an around-ear design with wireless connectivity and active noise-cancellation.

  • Sound is open, wide and suits most genres.

Headphones can be incredibly cheap or incredibly expensive depending on what you’re looking for. Audiophile-grade options will set you back thousands and even lakhs of rupees, while functional headsets purchased at a local store or from a street vendor might cost you less than the cost of your lunch. However, in between you’ll find plenty of headphones with different features and characteristics. Of particular interest these days are Bluetooth and active noise cancellation, and it’s now possible to get both of these in a headset at a reasonable price.

That brings us to the Infinix Quiet X. The brand is typically associated with smartphones, but Infinix is showing a bit of the same ambition that took Xiaomi to the top of the smartphone space in India. The company has brought accessories alongside its smartphones to India, and one of those accessories is this pair of headphones that we’re reviewing today. Priced at Rs 8,999 (but available at under Rs 5,000 on Flipkart right now), the Infinix Quiet X promises a lot for a price that isn’t too high. We review.

Infinix Quiet X Design and Specifications

While affordable headsets and options that have prices that are ‘too good to be true’ usually skimp in the build and design departments, the Infinix Quiet X is surprisingly pleasant here. With an all-black color scheme, the headset is good looking. The single metal quarter-circle hinges, matte-finish metal casing covers and clean round shape help the headset maintain a sophisticated profile. While the chunk of the build is plastic, the top of the casing is metal.

There’s also a fair amount of padding for comfort, both below the headband as well as on the ear cups. With an around-ear design, you also get a decent amount of passive sound isolation. The headset’s controls are on both driver casings, with the power, active noise-cancellation and 3.5mm jack for wired use on the left, while the play/pause, volume keys and micro-USB port for charging are on the right.

Interestingly, the Infinix Quiet X boasts of 25 hours of battery life on a single charge thanks to its 600mAh battery, but practically delivers much less (around 15 hours). This is still a fairly good figure, since the battery powers both the active noise-cancellation as well as the wireless connectivity to a source device through Bluetooth. Sensitivity is rated at 118dB, while frequency response ranges from 20-20,000Hz. There’s also AptX compatibility with supported devices, and you get a fabric carry case and charging cable in the sales package.

Infinix Quiet X Active Noise Cancellation

If you aren’t familiar with the concept of active noise cancellation, here’s a simple explanation of what it is. The headset uses its microphones to detect any continuous sounds in the surroundings of the user, and generates a reverse frequency that is piped through the headset to mute out the noise. Naturally, it doesn’t work with all sounds, as the headset can’t reverse all sounds in real time, but it works effectively with regular droning sounds such as machinery, the hum of an air conditioner and airplane engines.

While some headsets may only integrate active noise-cancellation without wireless connectivity, it seems only natural for any headset that has one of those technologies to also integrate the other. This is because both need power, and therefore an integrated battery, to run, so a single battery on the headset can power both functions.

When it comes to the Infinix Quiet X, noise cancellation is basic at best. The ‘vacuum’ as it’s described isn’t quite as strong as on more capable headsets, and there’s naturally a very audible difference between the Infinix Quiet X and the Sony WH-1000XM2, currently my favorite noise-cancelling headphones. Now, I’m not saying that the Infinix headset needs to sound as good as the Sony headset that costs about six times as much. Instead, the comparison is simply to point out that you’re getting what you’re paying for here.

Noise cancellation is simple, and the effect is ordinary. It might be effective in a relatively quiet environment, but with too much noise it isn’t quite as capable. In our usually quiet office, the effect was noticeable. However, out on the noisy street and in a vehicle, the effect was barely audible. Instead, the Infinix headset was better assisted by its passive noise isolation, and simply turning the volume up all the way.

Infinix Quiet X Sound

Although the price and Infinix’s lack of credentials as an audio manufacturer might have you believe otherwise, the Quiet X is surprisingly good. The large driver size is optimally used, and you get an open, wide soundstage. Combined with the slight benefit provided by the active noise-cancellation, this makes for a sound that is surprisingly good. Sonic separation is rather good for a device that is both affordable and Bluetooth-powered.

The sonic signature is a classic V-shape, but the focus isn’t entirely towards the low-end. The highs get a bit of attention as well, and you get a combination of good, clean bass and a hint of sparkle at the top. It’s an exciting sound that suits most modern genres, and is designed to appeal to typical music listeners. Don’t expect any audiophile-grade audio here, but what you get is a sound that is fun, appealing and incredibly good for the price.


I was pleasantly surprised with the Infinix Quiet X. It isn’t the best wireless headset you can buy today, neither is it the best at noise-cancellation. But for Rs 5,000 you’re unlikely to find a better headset today. It’s built well, gets the basics right and sounds as good a similarly-priced wired pair of headphones. However, the advantage here is that you get wireless connectivity and basic noise-cancellation (for what it’s worth). It’s definitely worth picking up if you want good affordable wireless headphones.
