I had the smaller version and wanted a fuller sound portable bluetooth speaker, but i did not want to spend a lot. The small version lacked bass & was ok at low to medium volume. In my research, i saw there was a larger version (a.k.a,Insignia Brick) which also could charge devices. When i got the Insignia Brick, i did my due diligence, as i always do with ALL my speakers (Mirage, Polk Audio, Paradigm, Bose, NHT, UE Boom, JBL) and take the time to break them in by playing the speaker at low volume for 40 hours. Many people make the mistake of cranking up the speaker to almost max volume as soon as they get it. IMO, you are overloading the speaker reflex, which in the long run will make the speaker sound distorted. I listen to a various types of genre so here is my feedback on the speaker. All types of music (jazz, piano, country, pop, heavy metal, rock, grunge, dubstep) sound great at low-to-medium volume. From medium-to-high volume, jazz, piano, soft country, still sound good. Medium-to-high volume does a descent job filling a 19ft x 14ft room. However, dont expect to feel like your at a dance club or rock concert. Unfortunately, heavy metal, rock, some pop songs, grunge, and dubstep sound a little muffled and lack some high treble tones. Dont get me wrong, it is not terrible, but dont expect crisp clarity or solid bass at high volumes. This is still a very good speaker to have with a couple of friends and music in the background, but dont expect a kareoke night. I love the portability of these speakers. I have other portable speakers, but this is perfect during my hotel stays on my business trip. It is 100% better than the iHome speakers typically in the hotels. I love my large UE BOOM speaker, but it is larger than what i want to you pack in my suit case. FYI, the UE BOOM that is not compatible with Alexa sounds so much better than the new UE Boom that works with Amazon Alexa. Hope this helps!!!!
