Alpine Corporation Waterproof Bluetooth Solar-Powered Outdoor Wireless Rock Speakers (Set of 2) – 50ft Range, Durable Wireless Sound System for Patio, Garden, Yard & Pool – Perfect for Outdoor Parties, BBQs & Backyard Relaxation

Easy to Bluetooth in stereo! Sound is better than expected.Solid mid-range. Bass is decent. And I’m a life-long bassist. Treble is good.But the two speakers sound great with stereo sound.Being placed on the ground reinforces bass frequencies.Exceeded my expectations! No not Bose sound, still the overall sound is impressive. Neighbors love it!FYI: set up one speaker as main speaker. Easy. Turn on second speaker by pushing big black button.Go back to first (main) speaker. Rapidly push small black button!Yes! Stereo!My speakers were obviously a return, probably because they couldn’t figure out how to set them up. With no instructions, I was up and running in 20 minutes.One Week Later: These speakers survived 3 days of extreme torrential downpour of intense Arizona monsoon rain! Was worried they didn’t make it! They still work great!Update on sound… These speakers are loud! Not deafening, but too loud for my front yard where it might be pushing the boundaries of my 10 neighbors on my block, including the ones across the street!Fidelity: The more I listen to the speakers, the more I love the sound quality! Even cranked up to the max, there is NO distortion. Very clean sound.Great midrange. Nice bass, no subwoofers, so no earthshaking lows, still good, acceptable bass.And listening critically, I can hear the hi-hat cymbals, and the ride, sizzle, and crash cymbals. Not quite as crispy as I would want in a perfect sound scenario, but still acceptable!But 99%+ of the average person out there is not an audiophile. My whole neighborhood is raving about these speakers!!And few have been on stage playing music for over 50 years…I love these speakers. Well worth the money! And if they can survive the Arizona heat at 115-119F even better.Design: After a week, I appreciate the design even more. Well-made. Sturdy. Monsoon rain-proof. Intense Heat-proof. Solar panels work great! Simple controls. Easy to set-up Bluetooth. Easy to set to stereo.Well worth the money!!P.S. After setting up the First Speaker (main) and turning on the Second Speaker, go back to the First Speaker and very quickly push the small black button twice! And now you have Stereo!!In conclusion, forget the expensive Boses! It’s party time. These speakers are awesome! Sound is great and it’s a good time for all!!!September 15, 2021:To Shawn: We both live in Arizona. My speakers have easily survived 115F heat. And all those heavy monsoon rains? No problem at all. Make sure those plastic plugs that cover the controls are fully inserted and completely flush with the rock.My speakers had no problems with all that endless monsoon rain.Never had any stereo syncing problems.To Everyone: To get stereo, push speaker one (main speaker) big black button to turn it on. You will hear a big beep sound. Now connected to Bluetooth.Go to speaker two. Push big black button to turn it on.Go back to speaker one and quickly push SMALL black button Twice!Now “quickly” means pushing that dang small black button TWICE IN LESS THAN A SECOND!!Hope this helps.Product is well-made. Works perfectly for me. And yes, NO instructions. Took me about 20 minutes pushing random buttons to figure it all out. No problem.I still LOVE my speakers!!September 23, 2021:Again these speakers can withstand intense heat, 115F; and heavy intense major monsoon rains for 3 weeks!!Can’t sync your speakers for stereo? Read my clear instructions in this post.Today’s problem: Today my 2nd speaker didn’t work. Wow! Totally bummed out!Even after all the proper button-pushing, still not working.Okay. Take it in the house to troubleshoot. It should be fully charged with the Arizona sun, but gotta be sure here.Plug it in with the supplied micro-USB cord. Solid red light which means fully charged. So I stare at that, thinking of my next move.After 2 minutes, I unplug the charging cord. Push the big black button to turn it on. It beeps!!And starts playing music!Now it works fine!!In Conclusion: still a great set of speakers. Solid sound. At max volume, no distortion, clean sound.Environmentally tough. At max volume, you may be too loud for your neighbors! Well-made. No complaints.Highly recommended!!(Pro musician on stage for over 50 years!)September 28, 2021 update:So my second speaker wasn’t working again. Went through my usual various troubleshooting methods! Could not get that 2nd speaker to work!!As a last resort, moved the speakers closer to each other than before.SUCCESS!!I have many Pagodas, Tikis, and Dragons in my front yard! But none of them block the speakers.The rock speakers are behind 2 large bushes about 15 feet apart. The speakers always worked fine.The rock speakers are hidden behind these bushes. From “inside edge to inside edge” between speakers was about 14 feet. To solve my problem of speaker #1 talking to speaker #2, I had to reduce that distance to 13 feet 6 inches! Yes only 6”!!Speakers sit on the ground. All distances are straight line-of-sight measurements.It is a little disappointing that the speakers don’t come close to manufacturer specs of “up to 25 feet apart!”Still great speakers. Very good sound. If you can live with 13.5 feet speaker separation, still 5 stars for me!October 11, 2021:Speakers not working again. Went through all my troubleshooting steps above.Red power lights are solid on! Good.But blue lights are off. Remember blue lights mean Bluetooth!!So bring rock #1 into house. Plug in micro USB charging cord. Blue light becomes solid in 3 minutes. Wait 10 minutes. Bluetooth seems to be fully charged.Repeat on speaker #2. All is good!Yes, a lot of fussing around to keep these speakers working! But definitely worth it.My big problem is not cranking up these speakers too loud!!I still love these speakers!!!October 12, 2021:Speakers not working again. But I can figure out anything!!Gotta bring speaker #1 into the house. Solid red light. Okay. Ready to go. Blue light out! Blue is for Bluetooth!!So I keep this rock plugged in with the supplied micro-USB charging cord.Solid Red Power light turns to Solid Green! Best power scenario.More importantly Solid Blue light turns to flashing blue light!! Never saw that on this rock!!Flashing blue light on any device means “I want to be connected to Bluetooth now!”Wow! So I use my rocks in the front yard maybe 2-4 times a week.Conclusion: I’m bringing in my rocks 1-2 times a week to fully charge them and see those solid green power lights and flashing blue Bluetooth lights!!These rock speakers are still amazing!! Great sound. Loud. No distortion. Clean sound at max volume!! Extremely tough weather-wise!October 18, 2021:These rock speakers still rock! Read the above review in its entirety.The only weakness in these speakers is they MUST be fully charged to work great!My front yard looks like a mini-Disneyland. I need these speakers to provide background music.So I only play music maybe 2-3 times a week.Still having occasional power/Bluetooth power problems!! Both need to be fully charged up to give optimal results.So now, I need to fully charge each rock. SO… each rock is individually brought inside.Charge first speaker with supplied micro-USB cord. Forget solid red power light. You want solid green power light!! Oh yeah.Forget solid blue light. Remember blue lights.. Blue lights are Bluetooth lights. You want flashing blue lights! Always the sign that a device wants to be hooked up to Bluetooth!!November 22, 2021 Update:So solid Green Power light is optimal. Fully charged.Correction on Bluetooth: Bluetooth light should be a Solid Blue when fully charged. If you turn on Bluetooth on your phone (or other device), then select the Alpine speakers; and only then the rock Bluetooth speakers start flashing blue lights.I usually test my main rock speaker (speaker #1) at this time. Might as well be sure it works before you place them back in the yard, pool, etc.Repeat charging process with speaker #2.Follow my posts about how to sync the speakers together, and how to charge these speakers!The techniques above ALWAYS works!December 3, 2021:Figured out if speakers are fully charged you can go 15+’ in separation.For optimal operation you have to charge each speaker inside for 3+ hours or so.I need to charge them every 1-2 weeks to make them work at full potential!You want that Solid Green Power Light on! After that, you may get a Solid Blue Bluetooth light, or maybe not. Push the big black button in twice. You should see a blue light, either solid or flashing. Any blue light is good!!If no blue lights, keep charging! lolConclusion:Still great sound. Environmentally tough. 115F+ and endless monsoon downpours… no problem.Will update post later this winter when temperatures drop below freezing!January 14, 2022:Two days below freezing. Speakers still doing great. Granted, it was only 30F degrees, lol. It does get down to maybe 26F at best. Will update if temps get colder!Took both speakers inside. Hooked up to flat screen TV. Totally deafening at 10!! Great clean sound, no distortion!!Put them back in the front yard. At 9, sounds great!! Still way too loud for neighbors. Now at 8.It’s the middle of the day. Seems my neighbors like classic rock. Still going to turn it down to 7.Conclusion: Great sounding speakers. Weather tough. I love ❤️ these speakers. No regrets. Extremely highly recommended!!!June 6, 2022:Bought another set of speakers. Today, impossible to set up in stereo. I know all the tricks about these speakers. New stereo syncing process has now been implemented with generation 2. Forget all those last year instructions.Make sure speakers are fully charged. Solid Green and Blue Lights.Turn on both speakers using big black buttons.Now push both small black buttons on both speakers, twice quickly. That means 2 times in a second.This should work. I will experiment with variations on this process.
