Short answer: the Harman Kardon Luna. It ranks #26 of 164 medium speakers by sound quality (rated 4.0/5) at $290.99 and is still sold new; the EFM Toledo ranks #152 (rated 2.2/5) and is discontinued, so it is only an option used.
The Harman Kardon Luna is the better-sounding pick. The sound is fairly balanced apart from the boosted bass. It charges over USB-C rather than Micro USB. The tradeoff: Boosted bass, and less detailed than higher-ranked speakers.
The EFM Toledo is the lighter option. A compact 1.1 lbs (500 g) speaker with dual drivers, IPX6 protection, speakerphone capability, TWS pairing and a claimed 15-hour battery life. At 1.1 lbs (500 g) it weighs much less than the Harman Kardon Luna at 2.5 lbs (1.13 kg). The catch: With only 10W output, bass is very limited and treble rolls off early, so music lacks the weight, detail and headroom of stronger portable speakers.
Buy the Harman Kardon Luna. It is rated higher for sound quality; the EFM Toledo is no longer sold new.

EFM Toledo: $99 Discontinued eBay
Pros: A compact 500g speaker with dual drivers, IPX6 protection, speakerphone capability, TWS pairing and a claimed 15-hour battery life. Its simple, rugged format makes it easy to carry for podcasts, background music and casual use around water.
Cons: With only 10W output, bass is very limited and treble rolls off early, so music lacks the weight, detail and headroom of stronger portable speakers. It has no aux input, app or EQ, and this discontinued model is best considered only if its compact weather-resistant design is the priority.
