Detailed feature review of Boult Audio AirBass Z1 earbuds

The Boult Audio AirBass Z1 earbuds are some very budget-oriented earbuds. Still, these earphones come with many features like Quick Pairing, Hands-Free Calling, USB Type C Charging, Bluetooth Version v5.0, IPX4 Water Proof & Voice Assistant/Siri. So let’s understand what these features mean to the end-user.

Built quality

Boult Audio AirBass Z1 comes with a good quality glossy plastic body and an excellent overall manufacturing finish. The case housing these earbuds is also very sleek & beautiful.

The sound quality of Boult Audio AirBass Z1 earbuds

The sound quality of these earbuds is average. The bass is good and also has deepness. However, if you are looking for a high-powered or strong bass, it will disappoint you. The loudness of the earbuds is good for typical usages. Due to its half ear design, the loudness & bass doesn’t feel that great for the outdoor environment. Other than that, the vocal quality in music is also average.

Everything being said, you can expect much at this price point. The sound quality you get is good for the price you pay. You can indeed buy it for casual video watching and listening to music, podcasts & audiobooks.

Driver size of Boult Audio AirBass Z1

The Boult Audio Z1 has a 13 mm dynamic driver. The driver is more than enough for a high-quality audio performance. The quality of the driver is average and lacks optimization. 

Microphone quality

There is a single microphone embedded in each earbud. The sound capturing capacity is good in indoor conditions. However, in outdoor conditions, you have to speak much louder, and it catches some ambient noise.

The half ear design and this kind of microphone quality make it not suitable for regular outdoor usages.

It’s not that the quality is worst and not useable but for outdoor usages but there are other better options for you to choose from other companies. Moreover, for regular usages of indoor environment microphone perform excellently in indoor condition.

Comfort & looks

The comfort of the Boult Audio Z1 is not good for wearing it during an intense physical activity like running & hard-core workout. It is so because it always gives you a sense of falling out from your ears due to its half ear design. However, it’s just a feel & it actually holds in the ears well, even during vigorous head movement.

Other than that, the material used to construct this earbud is good and skin-friendly. And long-duration usages are comfortable while using indoors.

Boult Audio AirBass Z1 looks very premium and stylish. The glossy look & sleek design make it look very desirable for anyone. It comes in three color variants- white, blue, and black.

The earbuds support Bluetooth v5.0 connectivity which gives you a range of around 9-11 meters. The distance varies depending on the environment you are in. the range increases as the obstacles between the mobile and earbuds are fewer. The overall strength of Bluetooth is good in these Boult Audio AirBass Z1 earbuds, and the reception doesn’t distort.

The auto-connect feature enables these earbuds to automatically get connected to the last paired device to open the lid of the case.

Sound delay

The company claims to have low latency in the earbuds. But when we tested, there exists the common latency that we get in any normal Bluetooth earbuds. The delay is noticeable in real-time online high FPS games.

These earbuds are good for casual usages for listening to music and watching videos on youtube. Still, we don’t recommend these for heavy gaming.
