    Love my speaker. From rap to classic rock it can handle any type of your choice of music. Only thing that I don’t like is the charger cord it comes with. It doesn’t always charge my speaker so sometimes I have to use a different Micro USB cord and it gets annoying.

    I was hesitant to get a portable speaker but I’m pleased with my decision. The sound quality is great, it’s lightweight, and I enjoy it very much there are a few drawbacks as there are with every piece of technology but it’s a compromise I am willing to make. The actual battery length without being plugged in is very short. Not at all as advertised.

      Hi Jose! Glad to see you're enjoying the big sound from the Megaboom 3! This speaker has a feature called One touch playlist that works with Apple Music, Spotify, and Amazon Music for example. Make sure to keep it updated with the Ultimate Ears app But if you have any questions, check out the Ultimate Ears support page at https://support.ultimateears.com/en/megaboom3/. Continue to enjoy!

    I was really excited about this speaker, as I have the original UE Boom..but I haven't been impressed. I don't know the technical language to describe it but, it sounds fine at a lower level, but anything above halfway does not sound very clear and sounds low quality. I've tried all the different options with the equalizer on the app and nothing helps..I feel there are better sounding options out there.

    Long lasting. Takes a bit to charged but after that it's last a long time. You can drop it and not worry that it will break. Not too heavy. Great for hiking or just chilling on your roof or deck with great tunes. Great app.

    We purchased this for our new home. We wanted something small and economical that would fill an open concept area. It produces sound that you wouldn’t believe comes from a little speaker. The app is great to customize your listening experience, too.
