Review: Great sound, solid little but hefty system! - Excellent speaker system! I wanted a sound as good as an Alexa, but without the internet snoopin...errr connectivity. This speaker faithfully picks up the bluetooth from your devices and plays with rich tones--high and low. I found the white Plus and Minus a bit conspicuous so I painted them black to match the speaker. One charge on the system lasts a good deal of time..I haven't found out how long yet..on my 3rd day of use!
Review: Audio Perfection - 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!

Love this speaker. Have it in my office. Holds a long charge. Sound quality is good. I like that it powers down (or goes into standby) when it sits idle for a bit.
