OSD Audio(Bluetooth Rock Speaker - BTR805, 20cm, Sandstone Canyon Brown) - 20cm 100W Bluetooth Outdoor Rock Speaker - Water Resistant, Pair, Sandstone Canyon Brown - BTR805

Tested them inside to make sure they worked, didn't sound so great. Installed them on the deck and there is a huge improvement in sound quality, and loud enough to be heard all over the yard. After several heavy rain storms, no issues.

They sound amazing perfect for your backyard

Sound is great and took about 30 minutes to install (wall, etc,.. all of it). Very easy.

perfect for the patio. Great !!!

This set of speakers sounds great out on my pool deck. It has decent volume - not blasting, mind you - but pleasant and full, even at its limit. It has enough to annoy the neighbors, if they don't like your taste in music. I've had no problem pairing them to several devices - that aspect has been a breeze. My only complaint with the BTP-650's is the lack of volume control I experience using my main device, a Motorola Droid Maxx running Android KitKat 4.4. This phone has worked flawlessly with every other bluetooth receiver with which I've paired it, and there have been many. For some reason these speakers will not respond to volume commands issued from the phone. This is an especially bad situation because they will only play at full volume, and these speakers do not have any volume hardware to offset the issue. It would really be a shame to get frustrated and feel the need to send these back because of possible software/bluetooth handshake problems. All these speakers would need is a simple volume knob and they would be five-star. I don't see them failing out-of-the-box for any other reason. I'm pretty much a techie nerd, so I've fought back experimenting with every volume control app I could ferret out. I've found one app (only one) that can get around the issue - and I wish I knew why this particular volume app works while all the others fail. It's beyond me. But at the end of the day I've sort of overcome the problem and I'm very happy with the rest of the convenience these speakers offer. No more dragging a boom box out with me every time I go out to the pool. All I need is my phone. The BTP-650's are very competitively priced for the quality provided. But if your main music player is an Android device - depending on your version and manufacturer, you should be aware that there is a potential issue. On a positive note, my LG G Pad running KitKat 4.4.2 and my wife's iPhone 4S work fine with these speakers. I'm sure most devices will.Pros:-Competitively priced-Quality sound-Decent volume-Convenient way to provide music on a patio or pool deckCons:-No volume hardware, which makes them more susceptible if there are bluetooth compatibility issues-Not entirely compatible with every device
