    long battery, durable, value for money
  

*by R***A on Reviewed in India on 23 September 2024*

After four months  the headphones still are as good as new. sound quality is Is mid range but the battery lasts for one week after full charge. certainly a value  for money

### ⭐ 1.0 out of 5 stars







  
  
    Constantly stops working for 4-5 seconds
  

*by W***. on Reviewed in India on 26 June 2024*

Sound quality is pretty average but I don't expect much from wireless earphones at this price anyway. However, the problem is that while listening to any audio, it suddenly gets muted for 4-5 seconds and then starts playing it again. I have to constantly rewind the video. I e-mailed the seller regarding a warranty claim (as there is supposed to be a 6-month warranty on renewed products but I haven't heard back from them). Highly disappointed and will never buy a refurbished product again.
