## Customer Reviews

### ⭐⭐⭐⭐⭐ 3 years of use
*by V***H on 17 January 2025*

It's been 3 years since I have bought this and it's working like a charm till now. Great sound quality ever in a gaming centric earbuds.

### ⭐ Poor quality
*by A***R on 28 November 2023*

The left ear-pod stopped working in just 20 days. Not sure who will fulfil the warranty ?

### ⭐⭐⭐⭐ Used for 1 week
*by R***P on 21 September 2024*

I used this for 1 week. To be honest, this is one of the best TWS that I've ever used. I'm a student and i always go for value for money options. The app for customization is really good. You can change colour(different colour options available), you can change brightness of the colour,different modes can also be turned on/off via the app and many more. Personally i liked it. But the only problem i found was the battery capacity. It's managable but if you're going for a long out, it may trouble you depending upon how much you use it. I used this most of the time and have to charge once per day. But for hardcore usage,and you don't touch grass, you may have to charge it twice per day. Mic quality is best, easy to connect and connectivity can be managed through app ,it is value for money,it's big but is comfortable for me and i liked the overall builf and premium feel it provides. I'll update more details after further usage
