These speakers are friggin awesome. Got one for each of my parents for their birthdays this year. The audio is crystal clear and it also gets very loud for its size without compromising the audio quality. Great for both music and podcasts etc. Also love that you can attach a carabineer to the speaker so you can hook it onto your pants or backpack etc and have the speaker effortlessly follow you around. The different settings/features are also really cool and handy. Would definitely recommend this product and honestly any product from the Ultimate Ears speaker line as in my personal opinion this line of speakers is the best line of portable speakers I know of or have ever heard. They're priced well too. I mean they aren't super cheap but they aren't overly expensive either, it's kinda right in that sweet spot. If you've got the money and you're looking for a portable speaker, look no further than this line because the sound quality and loudness (without distortion) you really won't find anywhere else especially for these prices. I know I'm starting to sound like a UE shill at this point lol but honestly I just really do love and admire their speakers and don't think they get the credit they deserve. Anyway hope this helps!

Overall this thing is super. Great sound, easy to pair & use, tremendous volume & decent battery life. The one unbelievable idiotic feature is battery charging. There's no light or sound to tell you ACCURATELY how full the battery currently is. If you press a button it will say "Normal Battery Level Enjoy The Music" when the stupid thing is somewhere between 36% & 100%. Are you kidding me? 36% is barely 1/3 full & there's nothing to indicate if it's actually 40%, 57%, 84% or 100%. What kind of engineer came up with this & how did it possibly get all the way into production with no one saying, "this is the dumbest thing we've ever made". I had a rechargeable speaker for my 2nd Gen iPod in 2002 with 4 little red lights, 1 light meant 25% charged, 2 lights 50% & so on. Simple, clear & easy, didn't need to talk to tell me absolutely nothing. So now 24 years later & these rocket surgeons can't pull this off with all the advancements in tech over the last 2 decades?

It looks exactly as the picture, the sound is really good. I'm going to buy a second one so can play both at the same time. Great quality i must recommend!!
