These sit in different size classes, so this is not a straight ranking comparison. The Ultimate Ears Everboom ranks #35 of 83 large speakers by sound quality at $117.17; the Soundboks Rider ranks #26 of 43 party speakers by sound quality at $599.
What the Ultimate Ears Everboom does well: Ultimate Ears Everboom uses 2x 56.6mm x 56.2mm fullrange transducers + 2x passive radiators. The catch: Careful placement and volume setting remain important for balanced sound.
The case for the Soundboks Rider: At 6.5 kg it is the lightest Soundboks yet, with a carry handle, IP66 dust and water protection, and the same swappable 100Wh battery as the Mix and Soundboks 4, rated for 35 hours at mid volume and 8 hours at maximum. Watch for: Its sealed 8in woofer runs out of real bass at high volume: Xander measured the -6 dB point rising to roughly 75 to 85 Hz at maximum, with 40 Hz some 20 dB down, and M1M heard the bass pulled back toward the upper bass above mid volume.
Buy the Ultimate Ears Everboom at $117.17 if you want a large speaker. Buy the Soundboks Rider at $599 if you want a party speaker instead.

The Two Speakers In Full
Ultimate Ears Everboom: $117.17 Amazon eBay
Pros: Ultimate Ears Everboom uses 2x 56.6mm x 56.2mm fullrange transducers + 2x passive radiators. Its 949 g, claimed 20 hours (Manufacturer specified) battery life, IP67 protection, aux input and mono playback make it a practical option for its intended room or portable use.
Cons: Careful placement and volume setting remain important for balanced sound. Warm tuning with an upper-bass boost and rolled-off treble, and the bass does not go very deep.

Soundboks Rider: $599.00 Amazon eBay
Pros: At 6.5 kg it is the lightest Soundboks yet, with a carry handle, IP66 dust and water protection, and the same swappable 100Wh battery as the Mix and Soundboks 4, rated for 35 hours at mid volume and 8 hours at maximum. Xander’s measurements found its flat profile genuinely flat, with distortion around 0.2 percent at moderate volume and below 2 percent from 500 Hz to 10 kHz even at full output, and the Indoor profile reaching down to 40 Hz at moderate volume. Both Xander and M1M Tech Channel preferred its punchy, controlled kick bass to the larger Soundboks Mix, and the app adds a six-band EQ with saveable presets.
Cons: Its sealed 8in woofer runs out of real bass at high volume: Xander measured the -6 dB point rising to roughly 75 to 85 Hz at maximum, with 40 Hz some 20 dB down, and M1M heard the bass pulled back toward the upper bass above mid volume. It measured 107 dB(C) outdoors for Xander and 113.2 dB(C) for M1M, about 3 dB below the Soundboks Mix and well short of the claimed 118 dB. There is no TeamUp, so it cannot link with other Soundboks speakers, the strap and charger are sold separately, and Xander found the grille causes dispersion artifacts around 5 kHz and judged the price too high for what it delivers.
