I think this is a great option for indoor or outdoor listening, even if I think I'll pair it with a sub so I can have a bit more umf at lower volume. And also when passing the 70-80% of volume, the base is no longer increasing. I only used it with Bluetooth, and I think this is limiting a bit the max power, but is a safe way of using it by anybody. Regarding the Bluetooth connection, I have a problem with my Samsung Note 20. The sound gets jammed sometime. But this is not a problem with other devides, Apple MacBook, windows laptop or Samsung S22, so I think my phone has some incompatibility problem. One more thing to mention, I used it at max power for 30-60minutes, and it started to smell as burned electronics. This might be that some new electronics have this "burn in phase" at beginning. Anyway I have 3years warranty so I'm not worried to burn it down :)) Overall sound and performance are great for the money. Will get you deaf if you stay too close for longer periods.
