Review: Great 👍🏻 - I've only had them for one day but they are really good. Well built, good sound quality with decent bass 👍🏻
Review: Fair for the price!! - I've had these for 3weeks now and they are very loud pair of ear buds and nice feel and touch to the earbuds and case. Bluetooth Connection is fast enough and battery life is pretty decent. However there is slight bass distortion when U turn it up beyond 75% but good treble and mid sound quality. For this price I can't complain too much. 🤓

### ⭐⭐⭐⭐⭐ Great 👍🏻

### ⭐⭐⭐ Fair for the price!!

I've had these for 3weeks now and they are very loud pair of ear buds and nice feel and touch to the earbuds and case. Bluetooth Connection is fast enough and battery life is pretty decent.

### ⭐⭐⭐⭐⭐ Top Audio Quality For Next To Nothing
*by R***L on 21 August 2025*

For the price, these earbuds have amazing sound. The sound they produce is comparable to that produced by earbuds that are hundreds of pounds more expensive. I tried a number of the earbud models from this Indian manufacturer, and there wasn’t one pair I wasn’t impressed with. Seriously, they cost about a tenner, you have no decent excuse for not trying them out yourself. Two thumbs up, for the entire range! 👍🏼👍🏼
