Short answer: the Bose Soundlink Flex. It ranks #38 of 164 medium speakers by sound quality (rated 3.8/5) at $79.99 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 Bose Soundlink Flex is the better-sounding pick. IP67 rated; rugged enough to survive drops from several feet and floats. It charges over USB-C rather than Micro USB. The tradeoff: Warm sounding with overly boosted bass which drowns out midrange detail.
Why pick the EFM Toledo: A compact 1.1 lbs (500 g) speaker with dual drivers, IPX6 protection, speakerphone capability, TWS pairing and a claimed 15-hour battery life. The tradeoff: 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 Bose Soundlink Flex. It is rated higher for sound quality and still sold new, while the EFM Toledo is discontinued.

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.
