There is no such button provided in the case to reset your earbuds.

Gaming Test

These Boult Audio earbuds come with a dedicated gaming mode with 45 ms low latency. You can access the gaming mode directly from your earbuds by pressing any earbuds four times. We tried the gaming mode of the earbuds with a BGMI game test and the earbuds impressed us. The volume, stereo separation, and in-audio experience were amazing, you could easily identify if the enemy was coming from left or right.

Overall, if you are looking for an earbud with a good gaming experience then you can definitely consider this earbud.

Sound Quality

With 10 mm dynamic drivers and SBC / AAC codec support, you get decent sound output with this pair of earbuds. The volume and vocals are pretty good in the earbuds, but the trebles and instrument separation could have been improved.

Speaking about the sound leakage, on sitting in a quite place there will be a slight leakage on listening above 90% volume.

The bass in earbuds is pretty decent. You will get the thumpy bass but the powerful boosted bass is missing. As a bass lover, you might feel that something is missing.

Calling Test

Boult Audio Z40 Pro earbuds come with a quad microphone setup with an environmental noise cancellation feature. In indoor conditions the call experience is amazing, and in outdoor conditions, the calling experience is pretty good. The vocals were focused upon and even though it caught some background noise the focus on vocals was pretty good in heavy traffic. So, if you are doing work from home or into regular meetings and calls, then you can consider this earbud.


Sound Quality: 8 / 10

Bass Quality: 8 / 10

Gaming Experience: 9 / 10

Calling Experience: 8 / 10


So, in this blog post, we have mentioned all the pros and cons of the Boult earbuds. Considering the price of the earbuds around 1600/- we feel that the earbuds are a bit overpriced. Had the price been around 1200/-, it would have been a good deal.
