Purchased at Easter, rich sound, pleasant, full, and above all neutral. Small speakers, big in performance! Being a fan of electronic music, I have thoroughly enjoyed them! The addition of Bluetooth is welcome and convenient. However, there is no option to turn off Bluetooth, just mentioning that. One thing that impressed me greatly is that for 5.25-inch speakers, it produces a sweet bass; it obviously doesn't shake the house, but it gives you the impression that there is a speaker (even if small) handling the low frequencies! Also, something I didn't like at all and really annoys me is the following: when playing at half volume (depending on the track), the air output comes from the back in a very large percentage; specifically, on the active speaker, there are two inputs for 3.5mm jacks (in front), and the air has to come out from there too, and since the inputs are of small diameter (as expected), a whistling sound is heard... I believe that with a little more study on fluid mechanics, this issue could be resolved, and the inputs could be placed elsewhere.
