soundcore - Motion X500

I have the Go 4, it is fine, if you can find a Costco nearby, they were selling packs of 2 for 30 dollars, not sure if that deal is still around, but even without the deal, it is a solid speaker. Default tuning is quite boomy but an EQ later and it should sound flatter, bass extension goes to 80~85Hz so it is solid for the size. With water on the front fabric it'll sound a lot more muffled, to be expected. The best deal I've seen on Amazon is the Motion X500 for 50 dollars. It is much larger, like MUCH LARGER, than those you're picking between and less portable, but I'm pretty sure it is louder and sounds better than them too. Given that it is basically 50% off the typical discounted price (original 170 dollars is bc they want to charge extra for spatial audio BS), I would suggest you give it a consideration if you can tolerate the extra size and weight.

Soundcore Motion x500 is on sale at Amazon for $50 right now! It has bass and treble but you can use the EQ to cut bass if needed.

You did not list the price of any compared blue tooth speakers. I just check the price of Bose Soundlink Flex and it's $190ca which is $40ca more than the Soundcore Motion X500. The Soundcore X500 is way better than the Bose.

Sound core Motion $300. For $60, it’s really hard to beat.

If you end up with the soundcore let me know and I will send you some equalizer settings that were done by a reviewer that I have followed for years and trust his measurements.

I have multiple sound core motion speakers and they are great. The onyx has way better bass. It’s not even close
