My friend recommended I tried the Treblab speaker and for the money it cost I have been seriously impressed. Has really good battery life, the distance I can be away from the speaker before it loses connection is excellent and of course the fact it's waterpoor is a life saver for when I'm on boat. A great product and glad I tried it when I did.

For top sound quality and waterproofing, check out the JBL Charge 5 or the Ultimate Ears MEGABOOM 3, both are great for boats.

Tribit Stormbox Flow is a good option.

This was a post from four months ago. Now the is a "pretty boy" contender: Anker Soundcore Boom 3i

JBL Boombox 3

Great list you’ve already put together. I’ve actually tried a few of these myself during hiking trips, beach days, and backyard hangouts, so I thought I’d chime in with some real-world impressions.

JBL Flip 5 – Durable, great sound, and solid battery life. Perfect all-rounder.

WONDERBOOM 3 – Super portable, floats in water, and has fun 360° sound. Not super bass-heavy but great for casual use.

Bose SoundLink Flex – Best sound quality out of the bunch. Rich audio, rugged build, but a bit pricier.

Sony SRS-XB33 – Loud with deep bass and cool lights. Great for parties and camping.

Soundcore Flare 2 – Budget-friendly, decent sound, and waterproof. Solid value for casual use.

If I had to choose, I’d go with the SoundLink Flex for sound, or Flip 5/WONDERBOOM 3 for balance of size and performance.

Also, I actually just put together a full blog post that dives into most of these and a few other options, including pros/cons, who each one is best for, and how they compare. If you're interested, feel free to check it out:

Happy to answer any follow-up questions too.

Tribit storm box micro

Bose Soundflex is completely waterproof and the bass should melt your face off in the shower.

Budget?

i have the original wonderboom (3 years old now) and it seems to fit your needs. sounds great, waterproof, loud for its size etc. they have newer ones u can find around $80-$100

Tribit stormbox blast is all of those but a little heavy. Anker motion boom + gets about as loud, doesn’t sound as good but is half the weight. Both are under $200

Try the Simo X: I've had it for about half a year now and each speaker breaks out into 4 subunits for surround sound. Not sure about the waterproof part though.

If you are talking about IPX5 minimum, then the Soundboks 3 at 126db@1m

If you are talking about IPX7 minimum, then the JBL Boombox 3 at 111db@1m

I wouldn't normally recommend these speakers due to them having worse sound quality than other options, but these are by far the loudest including waterproofing.

I know this thread is a bit old, but I wanted to chime in just in case you (or anyone else) is still looking for the loudest waterproof portable speakers. The Turtle Box is definitely a great choice. It's known for its powerful sound and durability with its IP67 waterproof rating. If you're after serious volume, it's tough to beat.

That said, there are some other strong contenders out there too, like the JBL PartyBox series, which packs a ton of power, and the Ultimate Ears MEGABOOM 3, which is compact, loud, and fully waterproof.

I also wrote a blog post specifically on the loudest Bluetooth speakers, so if you're still on the hunt, you might find it useful! It covers a bunch of options and compares the top performers in terms of loudness, sound quality, and waterproofing. Feel free to check it out for more insights!

Hope this helps, even if it’s a bit late! Let me know if you have any more questions.

All speakers are ranked here with maximum volume measurements. Choose what makes sense for your price and size limitations https://www.reddit.com/r/Bluetooth_Speakers/comments/z8bs6o/ranking_all_battery_powered_bluetooth_speakers/

The Turtlebox is no bass screechy not loud crap, there's a sound sample of it sounding awful in a linked video. They measure the max volume incorrectly in their own video. It's only 50w after all.

Jbl charge 5 hands down

Why?Want to disturb someone😂

Jbl charge is not completely water proof. I’m also looking for something with better water resistance. Maybe a cap for the plug ports and more gaskets around button board. We have 3 damaged from water at work. It’s the most reliable choice but we need something better. May end up having to make a speaker box with boat speakers.

Google sucks for this. I had the Jbl link …which was discontinued.

I hung an old original Google Home speaker in a wire basket tucked under the eave to protect it from the elements and it worked great last summer! Brought it inside for the winter, but hope to hang it again soon when the weather improves here.

If you can find one, Google chromecast audio.

I have one hooked to a small amp, sealed in an outdoor waterproof box on my patio.

Speaker wires run to yamaha outdoor speakers mounted on the wall outside. Works amazing.

Hard part is finding a Chromecast audio now.

The way I do it is with standard hardwired outdoor speakers plugged into a home theater amp with a Chromecast plugged into the HDMI.

So, if you want it to be a full Google home experience, the. Yeah you need to find something fancy...

But if you are just wanting something that you can include in your speaker group, or cast to, etc.

You can use any waterproof Bluetooth speaker, and pair it to a cheap Google home mini. Leave the mini inside near the wall that you want the outside speaker by.

The jbl link series have Google assistent and chromecast function built in.

Cheap amp + chromecast audio and running wires to proper outdoor speakers is still the best move unfortunately. You can try Bluetooth pairing with a current device in place of the Chromecast audio, but it may not sync well (or work well period).

Supposedly a google speaker can pair to any bluetooth speaker as its default output. Google has a page about it and the option is there in the Home app.

That said, I have never once gotten one to successfully pair this way, to anything at all.

About a year or so ago, I found a Sony SRS-XB402G that works amazing well with Google home. I'm sure they have an updated version.

If you're looking for a fully integrated setup, look at SONOS One SL. But, if you're willing to deal with something more modular that you'll be happy with the look and sound, I would suggest buying a normal pair of outdoor speakers and a Bluetooth amp.

This allows you to pair the amp to your Google device (I use a regular Google Home) and set up the amp up as the audio source. This is how I setup my speakers in my back yard and pool area.

There are a few drawbacks to this but I deal with them.

1. There seems to be only one BT chipset that is used in all the units on the market and it has a weird quirk. I bought three amplifiers (two FOSI and one other brand). On all three the buffer plays while it fills up. That is, when a new song starts, it plays for a brief second, then pauses and resumes. It just sounds weird, and it does it at the start of every new song.
2. For reasons unknown my Google Home sometimes just decides it does not want to be connected to the amp anymore. I thought at first it was another issue with the amp maybe powering down but I did some testing with that too with another device and it didn't seem to have any issues. But, these are cheap BT devices, so it is possible the amp is the problem.

I bought speakers off FB Marketplace at first, but after I realized this setup works well, I bought a 2nd setup for a larger set of speakers that I set up by the pool for larger gatherings. (that is how I tested multiple BT amplifier devices) - They all seem to work the same which leads me to believe they all have the weird buffer quirk.
