Dimensions: 180mm x 60mm x 50mm. It has 5 large control buttons on the top side, easy and direct operation. The cover of the 2 built-in speakers (the device is 2.0) is metallic, the back side has a strange but convenient surface that sinks when you hold it, for better control and to prevent slipping - initially I wondered what it could be. On the right side, there is the same material for the foldable cover of the connection panel, which has 3 ports: USB Type C for charging, MicroSD for external card, and 3.5mm Audio In for AUX connection. The battery (rated) is 2200mAh, I did not test if it actually lasts for 10 hours of continuous operation, which I consider excessive for a portable speaker and can be solved with a simple power bank - but it seems close to reality. The package includes a manual in Greek, a Type C cable for charging, and a 3.5-3.5mm cable. Simple connection with phone-computer (supports connection with one source at a time), recognized immediately, without problems. Sound quality is very good at the (rated) 10 watts, it is indeed 2.0, you can tell it is not monophonic, good volume, no noticeable distortions at maximum volume. It supports phone calls, you can hear and be heard perfectly. As for the negatives, the response of the 5 control buttons is a bit slow, but it is normal due to the waterproofing. The only real negative is probably that it charges with only 1A despite having a Type C port. For me personally, it is excellent in its price category, based on its features (10 watts, 2.0, USB Type C, hands-free, waterproof, memory card, AUX connection). I should add that even though it does not have a radio receiver, you can of course listen to the radio through an application or AUX.
