Short answer: the Soundcore Motion 300 is the better pick after EQ, while the Sony ULT Field 3 is the tougher, longer-running option with more system features. Their ranks are 3 of 175 and 75 of 175, respectively.
The Motion 300 has unusually deep bass for its size and can save separate EQ settings for upright, flat, and hanging positions. Its stock treble is too recessed, so use a custom EQ or raise the top treble bands; Signature is the better starting mode than BassUp.
Sony counters with IP67 protection, a 24-hour battery, phone charging, 10-band app EQ, and Party Connect. Its tuning can sound hollow and treble-forward, and selecting ULT bass disables the custom EQ.
Buy the Soundcore Motion 300 if you will apply EQ and want the more satisfying compact speaker sound.
Buy the Sony ULT Field 3 if battery life, ruggedness, phone charging, and large-group linking are your priorities.
Battery life favors the Sony ULT Field 3: rated for 24 hours against 13 hours for the Soundcore Motion 300.

The Two Speakers In Full
Soundcore Motion 300: $79.99 Amazon $79.99 eBay
Older model: the Soundcore Motion+ (ranked lower, rated 4.4/5). See every Soundcore Motion generation.
Same family: the Soundcore Motion 100 (smaller model, ranked lower, rated 3.7/5), the Soundcore Motion X500 (larger model, rated 4.1/5) and the Soundcore Motion X600 (larger model, rated 4.3/5).
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.

Sony ULT Field 3: $208.00 Amazon $208.00 eBay
Older models: the Sony XB33 (ranked lower, rated 3.4/5), the Sony SRS-XE300 (ranked lower, rated 2.8/5), the Sony SRS-XB31 (ranked lower, rated 2.8/5) and the Sony SRS-XB30 (ranked lower, rated 2.6/5). See every Sony XB and ULT generation.
Same family: the Sony ULT Field 1 (smaller model, ranked lower, rated 3.1/5), the Sony ULT Field 7 (smaller model, rated 3.2/5), the Sony ULT Tower 10 (smaller model, rated 3.9/5), the Sony ULT Field 5 (larger model, rated 3.5/5), the Sony ULT Tower 5 (larger model, rated 4.5/5), the Sony ULT Tower 7 (larger model, rated 4.7/5), the Sony ULT Tower 9 (larger model, rated 4.2/5) and the Sony ULT Tower Max (larger model, rated 4.8/5).
Pros: IP67 rated, dustproof and water resistant. 24 hour battery life. App with 10-band EQ. Party Connect with up to 100 speakers. USB-C in/out for charging your phone.
Cons: Sounds a bit hollow, a bit boosted in the treble. Custom EQ and the ULT bass-boost button can’t be used together: turning on ULT disables the EQ. Bass is very weak with ULT off. Lost to the JBL Charge 6 in a side-by-side comparison despite being the larger speaker.
