First of all, I have to say that it is not worth it due to the price. With that amount of money, you can get another category and more powerful one, I must say. The speaker is decent in terms of construction for its price, BUT it doesn't have its own volume. What do I mean? The speaker itself doesn't have the ability to increase or decrease the volume, but it adjusts the volume of the mobile phone with its own and delivers the supposed 20W. I can say it has strong bass, really, even though it is what it is. The sound is crystal clear, no connectivity issues, waterproof, the battery has lasted up to 8.5 hours and not the claimed 10 (maybe the mobile phones show battery percentage, I don't know why). Overall, satisfied with what it offers, but I repeat, it is not worth it due to the price (for me personally - it was a gift for me and then I saw the specs, etc.)

The bass and speakers make so much noise that even at low volume it distorts a lot, especially the vocals.

As a construction, it is very high quality. Strong bass, but for those who don't like bass, an app with an equalizer is needed to listen to a bit more treble and quality. I consider the radio not as an extra but necessary for such speakers. Generally, value for money, I have had it for 2+ years and it is used quite a lot.
