Decent purchase
Battery life is decent. Sound quality is excellent. Noise cancellation for such a small ear bud is amazing.

Great value earbuds
I've had several different brands of earbuds, these hold a place of their own. Firstly: Their battery life will last forever many hours. I've used them upwards of 7 hours straight without dying. The case power life can go days without needing to recharge from multiple uses. Sound quality isn't quite BOSE but does deliver clear quality. One downside in my opinion, although given various size rubber ear cones I struggle to find one comfortable to fit my ear, maybe the shape, or maybe my ears. All in all excellent value for the price.

Actually very high quality
Genuinely best headphones ive bought for this price. Way too cheap for how good they are. I wouldn't buy them for £50 but for £10 they were actually a steal.

BOULT EARBUDS
They are not the best sounding Earbuds, but you can't expect anything more than average for the Price, I just bought them as secondary to my Airpods Pro and my JBLs. But glad I bought them to run around use.

Boult earpods
The boult K40 are very good all round Bluetooth ear phones which offer true value for money. They have good noise isolation, amazing call quality even with a noisy background like a busy street etc. The audio quality is quite good with clear music and top notch bass. The battery life is the high point for these head phones. They sit very comfortable in the ear and stay in place even during intense physical activity. I am extremely satisfied with this purchase. The delivery happened within two days of my purchase.

Decent TWS but charging could be better
Why did you pick this product vs others?: Nice TWS earphones under ₹1000 . Nice audio, good battery life. However after 1 year of use there was some trouble in charging one of the earbuds in the case. I used to adjust using a piece of paper to make it sit in a position where it continued to charge. Also the case is not waterproof it is not working since I got drenched in rain with it in my pocket. So, decent product needs to be handled carefully.
