### ⭐⭐⭐⭐⭐ A good little speaker
*by B***R on 31 December 2023*

### ⭐ Didn't last well
*by T***E on 15 May 2025*

Bought these on 10/05/2024 as of 15/05/25 one of them has popped and now vibrates, they've never been hammered, I very rarely listen to them at a high volume, very disappointing! I know they aren't the most expensive, but I was expecting them to last longer than a year!
