Short answer: the JBL Flip 4. It ranks #63 of 136 medium speakers by sound quality at $70; the Ultimate Ears Roll 2 ranks #125 and costs $100, so there is little reason to consider the other one.
What the JBL Flip 4 offers: Less bass than a Flip 5. Peaky lower treble. Watch for: Battery failures are common.
What the Ultimate Ears Roll 2 offers: Thin, flat profile fits easily in a bag or purse; light at 0.73 lb. Built-in bungee cord for hanging from a hook, nail, or door handle. Life-resistant waterproof/dustproof shell. Watch for: Not stereo. Barely any bass, rolled off treble off axis
Buy the JBL Flip 4. It ranks higher for sound quality than the Ultimate Ears Roll 2 and costs less, which settles it without a real tradeoff to make.
If sound quality matters at all to you, skip the Ultimate Ears Roll 2. It ranks near the bottom of the 136 medium speakers, so look higher up the list instead.
