Bests & Worsts Reviews from Amazon

I have two opinions of the Ultimate Ears Boom speakers. When used as a single speaker, the Ultimate Ears Boom 3 speaker works well. The sound quality and loudness are good for a speaker of its size. The Bluetooth range is rather pathetic as I lose connection after moving about 20 feet away from the speaker's audio source, but I blame Bluetooth for being a lousy wireless standard more than the speaker for that fault. The speaker can be used every day in the shower with no negative repercussions. Overall, the Boom 3 speaker is a great speaker when used by itself. The situation completely changes when attempting to use two or more Boom speakers together. I'll go into details below, but I can confidently say that I've experienced few pieces of technology that are more unreliable and frustrating than the Boom 3 speakers when trying to get them paired together and playing the same audio. First, the Ultimate Ears Boom app is a huge frustration. Getting even a single speaker to show up in the app can require multiple disconnects, app force quits, and speaker restarts. Once a primary speaker shows up in the UE Boom app, getting other speakers to show up is near impossible. Each and every day I want to use the speakers together, I have to go through a 20-minute process of forgetting Bluetooth settings, repairing, and powering off and on speakers. It is such a frustrating process that I usually rage quit and forgo using the speakers together. Then, once the speakers are connected together they regularly start clicking and thumping as they stutter during audio playback. Even when I move the two speakers within a foot of each other and the audio source, they regularly and constantly stutter and lose bits of audio. Listening to an entire song without missing parts is impossible when using the Ultimate Ears Boom speakers together in Party Up or Two-Up mode. Simply put, THESE SPEAKERS DO NOT WORK WHEN PAIRED TOGETHER. The Boom speakers are completely worthless when used together as the audio they play is unlistenable. I really enjoyed the single Ultimate Ears Boom speaker I used on its own for about two years, but after experiencing the disaster which is Party Up mode and the Ultimate Ears Boom app, I will never again purchase another Ultimate Ears product. This experience has just been too frustrating and I've wasted $300 on two speakers I cannot use together.
