These are not really the same size class, and that is the honest framing here. The EarFun Uboom L ranks #2 of 179 medium speakers by sound quality at $49.79; the Soundcore Boom 2 ranks #10 of 120 large speakers by sound quality at $99.99.
The EarFun Uboom L is the lighter option. A great value medium speaker with clear, natural sound, waterproofing, and a Video Mode that keeps audio in sync with video. At 1.4 lbs (650 g) it weighs much less than the Soundcore Boom 2 at 3.7 lbs (1.68 kg). It supports AAC Bluetooth, which the Soundcore Boom 2 lacks. It keeps a wired aux input, which the Soundcore Boom 2 lacks. The tradeoff: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail.
The Soundcore Boom 2 is the deeper-bass, longer-running option. A light, waterproof large speaker with deep bass for its size, a 24 hour battery and fun lighting. Its bass reaches about 47Hz before falling 10dB, against 56Hz for the EarFun Uboom L. It is rated for 24 hours of battery against 16 for the EarFun Uboom L. It links with other speakers (PartyCast 2.0 up to 100 speakers), which the EarFun Uboom L cannot. The catch: Only a single midrange driver, so you only get stereo for the tweeters.
Buy the EarFun Uboom L ($49.79) for a medium speaker; the Soundcore Boom 2 ($99.99) suits a large speaker instead.
