### ⭐⭐⭐⭐ Good in 699 Price
*by A***N on 20 January 2026*

Good Products Battery backup and sound quality also good but not comfortable in ear right side

### ⭐⭐⭐⭐⭐ Well Balanced and Quality Earbuds
*by A***A on 1 March 2025*

The Sound Quality of these is quite balanced, nice mids, prominent lows and smooth highs. I would also acknowledge its pairing speed and working distance while using, gets its job done. Gets charged in an hour or two and the earbuds inside gets charged in nearly half an hour. So it won't keep you waiting. Another Pro is its calling mic, which is quite decent to me, inside room its quite good and clear on call though outside it catches nearby sounds a bit but the voice is audible to the caller. The real USP is its PRICE, at Rs. 699/- it was steal deal to me given the sound quality and its range. I can't really expect a CON at this price point but the only one according to me is it doesn't have a ANC/ENC thing so it maybe noisy to the caller when using outside but otherwise it lives to its merit.
