Soundcore Boost “upgraded” 2021 vs Ultimate Ears Boom 3

Last updated: August 28, 2026

Short answer: the Soundcore Boost “upgraded” 2021. It ranks #4 of 136 medium speakers by sound quality at $60; the Ultimate Ears Boom 3 ranks #89 and costs $129.90, so there is not much of a tradeoff to weigh.

What the Soundcore Boost “upgraded” 2021 offers: A very neutral good sounding inexpensive small speaker with quite deep bass for the size. This upgraded version has a usb-c port while the old one has micro usb. Watch for: Slight DSP tuning issue which makes bass get lighter at times at very low volumes, examples in oluv’s video.

What the Ultimate Ears Boom 3 offers: Rich and warm bass without muddying mix, crisp highs, excellent 15-hour battery life, stable Bluetooth connectivity, IP67 rated and floats, rugged fabric shell, can pair up to 150 speakers via PartyUp Watch for: Not stereo, barely any bass, recessed treble. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2021. Lots of mentions of failing batteries on amazon. Not technically a 360 speaker, only front and rear.

Buy the Soundcore Boost “upgraded” 2021. It ranks higher for sound quality than the Ultimate Ears Boom 3 and costs less, so the other one has nothing left to offer.
