ECOXGEAR GDI-EXBM913 Waterproof Portable Bluetooth/AM/FM Wireless 100W Speaker and PA System, Royal Blue

I almost returned this until I found out the EcoBoulder has a hidden Equalizer w/ 5 Presets: 1)Default (poor sound) 2)Jazz, 3)Rock, 4)Heavy Bass, 5)Heavy Treble.Just hold Play/Pause button for 1 second & release to try each preset. FYI-the EQ presets only works with Bluetooth. This is perfect with my streaming music apps. SEE PIX.My favorite is preset is Heavy Treble (clear). I couldn't hear the differences among Default, Jazz, & Rock presets. Maybe noticeable when it's blasting outside.At first, I thought the poor sound was due to waterproof seals. I guess the manufacture forgot to mention this EQ option on their website and user manuals. Sound issue was also answered in the Q&A section if you have time to search the list.

I purchased a refurb of this speaker to take to Burning Man 2017, and it did NOT disappoint! The speaker is loud, durable, dust resistant and the battery seems to last forever. We would use it around camp and it only needed to be plugged in once a day for a few hours, and we never ran out of juice. I dragged it around the playa using the handle and wheels and got it really REALLY dusty, didn't complain, and made a great seat out on the playa.Did I mention how LOUD this thing plays? None of us could believe it, but we certainly appreciated it! Plus the fact that it worked the entire 9 days that we were on playa is a testament to its durability. Everything seems to break down out there, but not the EXOGEAR playa proof portable speaker.

STOP!! SOUND QUALITY/VOLUME WARNING.Long review made short.I am comparing this to my Bose Sound link Mini which I love and produces an unbelievable amount of bass for its size.At first I was not impressed with this unit out of the box.Highs were good.Mids were good.Lows.. ok I guess.After searching for the EQ settings and flipping through the owners/operators Manual I couldn't seem to find any.However, remembering I had read someone complaining about low bass in and adjusting on the EQ I began to search reviews to find where the reviewer was adjusting.By pressing and holding the play/pause button for one (1) second while playing music, you can select from 5 different EQ Settings.I now keep mine unit on "heavy bass".Now, here is my rating on the sound quality.Rating 1 to 10. (10 being best).Highs: 8Mids:8Lows: 8Volume:8I am satisfied with this speaker quality so far, I have not taken it on any trips or outing yet but will update on durability after beach vacation next month.Overall, without going to professional sound equipment this unit unit is impressive.Also be prepared to wait for this unit to arrive.The unit took 14 days to arrive at my door (4 days longer than they estimated)Also company did not provide tracking number until I inquired on the first day it was late.

This speaker is one of the best things I have ever purchased! Just unpacking the unit, it looked and felt like good quality. The sound is amazing and I am extremely happy with this purchase thus far. I am looking forward to taking this on the dock with me this summer so I can actually hear the music when in the water!

I'm updating my review on these since I've had issues.I have a pool and I set them up at one end on either side which makes for a great pool party experience. I usually connect to one from my laptop via Bluetooth, sync the two together, then play music from my Spotify on my laptop and use my phone or set a Kindle on top to manage the playlists within Spotify. These are cool because I can turn them on connect and sync them while still inside, then wheel them out, and put them away or move them with the music still playing. They run several hours at normal volume levels without having to be plugged in to charge, which is cool too.I used to love these, but have found a couple issues:1. Not waterproof.Since the warranty was still good on these (I bought the first one on impulse from Costco), I decided to chuck them in the pool to show my MIL how cool they were. Within a week or two they both stopped working due to issues with the buttons not working and the LCD screen not displaying correctly.2. Warranty process is not solid.When the first one went bad, I contacted the company and the person I worked with asked me to email her a video of the issue with my phone along with my my receipt from Costco. She immediately sent out another on the next day and set it up so that I got email updates on the shipping. Service was great!!! When I received it, she even included a shipping label, so all I had to do was put it in the same box the replacement came in and drop it off at UPS to have them ship it free of charge to me. Easy-peasy!!!No sooner did I get the replacement shipped off and I noticed issues with the second one. This one was a lot more difficult. I was working with a different tech, but I provided a video and used my cell phone and order number from Amazon, but it took a while for him to respond to me. Then when he finally decided that he was going to replace it under warranty, he sent me a link where I had to print off a "label" (not from UPS), then take it to UPS to have them package and ship it for me. This cost me about $115. I originally spent $130 for the unit so that wasn't cool. I did receive a new replacement for the second one after about a week.I'm not going to put them in the water again.
