The Two Speakers In Full
Soundcore Motion 300: $79.99 Amazon eBay
Older model: the Soundcore Motion+ (ranked lower, rated 4.4/5).
Pros: Pretty deep bass for the small size. Pocket size in a big pocket. Can be used in stereo facing you, or omnidirectional lying down. Ability to have a custom EQ for each orientation, standing, lying flat, hanging. Try the Uboom L EQs from Oluv for a more neutral sound. Measured bass extension of 50Hz (-10dB).
Cons: Without the above EQ or turning the top 2 treble EQ bars to max, this speaker is very rolled off in the treble and will rank around #50 in the rankings. Bassup mode is worse than Signature. Not quite as detailed or neutral as higher ranked speakers. Slight bass distortion when turned up.
