Bluetooth codec support
P1
Product 1: Sonos Move 2 Portable Speaker
3.0
Bluetooth relies on basic codecs like AAC and SBC and lacks higher-res options such as aptX or LDAC, so Wi-Fi and AirPlay are often preferred for best fidelity.

P2
Product 2: Ultimate Ears Wonderboom 4 Speaker

Float behavior is generally positive, but multiple sources mention practical caveats: audio may not play while floating, sound can change when wet, and it may tip over in the water so the sound does not project as expected.
Frequency response balance
P1
Product 1: Sonos Move 2 Portable Speaker
4.2
Most reviews praise a balanced tuning with punchy bass and clear highs; a few listeners found upper mids or vocals slightly veiled until EQ tweaks.
P2
Product 2: Ultimate Ears Wonderboom 4 Speaker
4.2

P2
Product 2: Ultimate Ears Wonderboom 4 Speaker
4.0
Maximum volume is widely described as impressive for the speaker size and capable of filling small to medium spaces. A recurring theme is that the best listening is below max volume, where quality holds together more reliably.
Low-volume performance
P1
Product 1: Sonos Move 2 Portable Speaker
4.1
With the loudness feature enabled, it retains body and bass at lower listening levels, helping it sound fuller when used casually indoors.
