Good overall earphones
Canât really fault these for the .. managed to get them for £9.99.. they have a good overall sound quality and are louder than others at this price point.The bass is very strong, I had to adjust Spotify equipment as the bass was too much .. not something you can always say.

I’ve been using this product for a very long time, about a year now. As you can see from the casing, there are some scratches, which are my fault for not being more careful! Overall, it’s a fantastic product. The sound quality is great, and the Bluetooth range is also quite good.
