Alpine CorporationWeather-resistant Bluetooth Solar-Powered Outdoor Wireless Rock Speaker - Set of 2

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.

We just moved to California from Massachusetts - and we wanted a drought friendly, cool looking SoCal backyard. As part of that plan, I knew I wanted some kind of audio system to add some ambience and really make the new yard POP. I ordered these to achieve what I was looking for, and they do not disappoint.I did have an issue when I first set them up with bluetooth not connecting properly. I'm using an older iPod as my audio source, and it's about ten feet from the speaker closest to the house. Sound would cut in a bit so I swapped the speakers - assuming one had the bluetooth receiver and would work better if it were closer to the sound source. Well that did the trick and I was good to go.The second speaker needed to be placed a few different places to get it to work smoothly with the first. I ended up having to place them quite close together, and based on reviews from others, I knew they might have to be closer than specified - but these seemed to be not working properly. I called Alpine on a Saturday afternoon (texted actually) and I received a response immediately! (on Saturday?! WOW!) A very nice young lady named Shadelle went over my installation, and determined they should not be working they way they were. She set up a replacement for me, and it's on the way via Fedex for delivery just a couple days after we spoke. Great customer service - excellent product!You're not going to get rumbling bottom out of these due to the speaker size and type of enclosure - but you will get very clean and loud sound. I run them with the iPod at the halfway point for volume, and they sound really good. We get LOTS of sunshine, so these bad boys get a nice full charge while the sun is shining, and play all day and into the night without shutting off. So kudos to Alpine for the customer service, as well as the great product.Yes they seem like they are expensive for a rock that makes noise - but they do it well and are well worth the investment!

I purchased a pair of the Alpine Corporation Waterproof Bluetooth Solar-Powered Outdoor Wireless Rock Speakers on 6/11/23, and unfortunately, within just 12 months, one of the speakers has already failed due to exposure to the elements. Living near Austin, TX, which isn't particularly wet, I was surprised to find that the 6" speaker had been water damaged. Upon disassembling it (I'm an electronic engineer), I found that the retaining nuts for the speaker had rusted, indicating poor resistance to moisture.The sound quality is subpar, and they seem underpowered. Despite the product notes claiming a maximum of 6 Watts, I suspect the speakers each have only a 3-Watt amplifier chip, given the misleading specs in the comparison table managed by Amazon (describing it as a 12" speaker).The one positive aspect was the Bluetooth setup, range, and performance, which are typical of Bluetooth speakers. For this, I would give it 3 stars. However, the overall experience with the product's durability and sound quality leads me to rate it 1 star. I expected more from a product at this price point and marketed as waterproof and suitable for outdoor use.

Great product, love the look and easy to use. I’ve seen reviews with issues on syncing, but we followed the instructions and had no issues at all!We had some issues initially with one of the speakers and the customer service team was quick to respond and offer a solution.We love the product. Sound is good. Volume is controlled by your phone. Charges last and is quick to charge.We would definitely buy again!
