  • Boltt Blast 140 Bluetooth Headphones
  • 5mm cable
  • Micro USB charging cable
  • User instruction manual


Right from the built to the design, Boltt has focused on the premium buyers here. The headphones have a generic design but with some catchy materials like for instance the glossy patterned earcup shell. They might look bulky at first but are equally comfortable at the same time. The ear-cups have a swirl motion and they turn inwards, making them easier to put in a bag.

On the right ear cup, you will find a power button, a 3.5mm for using the headphones in wired mode, and volume controls. The buttons are tactile enough that you get a satisfying feeling from them.


The pairing process is easy and simple, long pressing the power button powers on them and they go straight into pairing mode. Sticking to their naming, the headphones are a little more bass-heavy, which is generally the case with the headphones in this price category. The highs and mids are decent with the vocals being a bit dull to our liking.

There is always a constant amount of bass available which is always enjoyed and craved by the Indian audiences, so here’s where the headphones make a solid case for themselves. The overall soundstage is flat, so for people wanting a little more diverse soundstage, this is not the right choice.

Image09In our tests we found out that sound leaks from them at volumes above 75%, so we would suggest you set the volume below that levels for an enjoyable experience. Call quality via the in-built mic is decent at best. Coming to the battery life, in our test, the Blast 140 lasted for 20 hours which is a little shy to figure that the brand quotes. They take close to 3 hours for a full top-up.


  • Good call quality
  • Decent design
  • Amount of bass


  • micro USB charging
  • Flat soundstage

Verdict – Should you go for it?

Image01 2Overall, the Boltt Blast 140 premium is a decent pair of wireless/wired over-the-ear headphones. They have a clean yet catchy design with a 3.5mm audio jack is a welcome addition. We quite liked the battery backup on these, making it ideal for prolonged listening sessions. As mentioned above, they are a bit bass-heavy which might not be enjoyed by everyone, perhaps a more dynamic soundstage could have solved the issue.

Rest assured, coming in at INR 2,999 they do sound good and worth a recommendation.
