Title: Clean Sound
Review: Clean Sound.The UE Boom 4 is a good speaker. Music sounds clean and clear, and there is a lot of articulation in vocals and individual instruments for a speaker this size. Bass is decent, but do not expect the deep bass you’d find in JBL or Soundcore Bluetooth speakers in the same price range. The Boom 4 is very close to the Megaboom 4 in terms of sound quality, but the Megaboom 4 has a bit more bass and can reach higher volumes. I think this speaker is good for a small office or bedroom, and it is small and light enough to be carried around and used for small outdoor gatherings. I definitely recommend it, especially for what it costs.

Title: It's a great speaker, but...
Review: It's a great speaker if you're a podcast listener. Sound and quality are top notch. However it fails when it comes to music. There is absolutely no bass. If you're like me when it comes to music, buy a bose.

Title: No boom
Review: Clarity and package is good, but at this price, you can do much better. Not enough bass.

Title: Surprisingly underwhelming
Review: I wanted something small and potent to take out and that was easy to carry around and since I own the Hyperboom and I instantly fell in love with it, I thought the boom was going to blow my mind. I was wrong and I was disappointed.The sound quality was not terrible but it definitely wasn’t for my ears. The base was non existent and the rest of the sounds seemed bland. It really sounded like a whole lot cheaper speaker. If you want something this small and that will have decent sound, go for a JBL.

Title: Far exceeds my expectations
Review: Purchased this mainly for same day delivery as my Bluetooth speaker went out while doing yard work. Wasn’t excited about the price, but after using it for the afternoon I’m thrilled with my purchase, it sounds great, nice and loud, and has good range from my phone. I will be purchasing an additional speaker, as you can pair multiple together.

Title: Junk
Review: The sound quality is ok, because it is not very loud. At full volume, the battery will be completely dead in 4 hours. At 3/4 volume it will be dead in 5 hours. It doesn’t charge while plugged into a usb automobile cigarette lighter.I bought the mega boom 3, it was certified refurbished, I wasn’t paying attention, a co worker sent me the link, 3 songs , the speaker was rattling, and by the time I got home from work, it was filled with water.I am a city letter carrier in Vegas, I am outside at least 7 hours a day, and just from leaving a cooling towel on the already rattling speaker, it managed to fill this waterproof speaker with a cup of water, and it never worked again.So whether it’s new or refurbished, I can honestly say that Ultimate Ears Boom4 and mega boom 3 are crap.I had a $28 dollar JBL, that was as loud, and took 2years to blow out the speaker.I am assuming the megaboom4 is no better.

Review: I bought this speaker as a friend has the older version and its an amazing speaker. Great sound quality, good battery life and some amazing added features like PA system and party mode.The only reason for the 2 stars was the false advertisement. The speaker style said it was the Megaboom 4 and was a crazy good deal however what I actually got was the boom 4. I even clicked on all the colour options to try and confirm that I was actually getting the Megaboom but alas it was not.Be careful what you click on and make sure you go through the entire listing before making the decision.
