OSD Audio Outdoor Bluetooth Speakers BTR150 BTR805 BTP525 BTP650 Review: 6 STARS How to set these up. Never loses Bluetooth connection. Powerful quality sound. No problem with sprinklers 3X a Week - Maybe the best item I've ever purchased on desertcart for the money. I rarely give five stars.The speakers maintain the Bluetooth connection with Alexa from 30 feet away through a double pane glass window. The sound is absolutely awesome. It is equivalent to my 200 W Logitech speaker system except that the base does not pound quite as hard as the Logitech. It is important to spread the speakers no more than 20 feet apart. The speakers will then create a cone of stereo sound with the apex about 50 feet away from the speakers. I have the speakers in my 50X100 backyard which is next to a busy street And when the speakers are on level 10 you cannot hear any street noise at all unless a Harley goes by. These speakers get hit by my sprinklers three times a week and I have not had any problem at all. I have the speakers set on the ground at HIGH POINTS that are elevated approximately 2 inches from the surrounding groundSo they will not be subject to any ponding water. I have the power supply inside of a waterproof electrical connection box which cost seven dollars. There are many different kinds of these available on desertcart and they are made specifically for this purpose. I also have my 120 V outdoor lightS electrical connections inside the same box. I have been researching outdoor speakers for a long time because of the road noise in my backyard. The first one I bought for more than $200 is the acoustic research Hatteras outdoor Bluetooth speaker which cost more money than these two rock speakers. The HatterasTurns off automatically when it does not receive Music overBluetooth for more than three minutes. That is extremely annoying and there is no way to turn it off! I talked to several people at acoustic research technical support. The Hatterasis only one speaker so it cannot produce stereo sound,And the quality of sound is nowhere close to these two rock speaker's. The Hatteras does not even compare to these two speakers even though it cost more money and it has great reviews on desertcart and other websites. Review: Great purchase. - I was looking for 3 things for my front porch: Outdoor, wired to a plug (not needing to charge a battery), and bluetooth capable. I don't want to have to plug my phone into some cord every time I want to play a song. I don't want to worry about charging a portable speaker. I wanted the speakers to just always be on and ready to connect on my front porch. Five important things that I didn't get from the other reviews: 1. These were way bigger than I expected. The 5.25" is the size of the inside speaker but the actual size of each case is much bigger. I was ok with this; just surprised when I opened the box. 2. Many reviews say the speaker wire between them is 10'. The power wire connecting the 1st speaker to the outlet is maybe 10' and the wire connecting speaker 2 to speaker 1 is more like 20'. All wires are black. I wrapped them in white electrical tape to blend with my house trim better. 3. Mine didn't have instructions on how to mount but it was basically self-explanatory. It was also missing 4 screws that would mount it to the house. So I'm not sure if this was a mistake but it was a pretty easy thing to resolve. I used some screws from the garage and they worked just fine. I used Everbuilt size #10x2". I'm sure yours will have the mounting screws...but who knows. 4. When I first plugged these in to test the sound was inside and they sounded just so-so. My wife suggested I try them outside since they're outdoor speakers. So I did and they sounded amazing! I don't know what kind of voodoo magic it was but these sounded fantastic once outside so be sure to take yours outside to hear them. 5. Bluetooth connecting is really easy. I did go to my garage out back and lost connection. When I returned the music was off and I had to reconnect but that was easy to do. This is the whole point of why I got them. I want to be able to pull my phone out at any given moment and just connect. Always on, always ready, no wires. Just connect and play. For a little over $100 this was a solid purchase. The sound is great, installation was super easy (assuming you can drill/screw into something), and connectivity is easy. ## Features - SOUND QUALITY: The BTR150 Outdoor Rock Speaker kicks out 120 watts of high power, producing a clear and rich sound.

So based on another reviewer's suggestion, I added a sub-woofer to the system. Specifically, I added a "Rockville, Rock Shaker 10" found here on Amazon. https://www.amazon.com/dp/B09ZD238Y2?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1&th=1 The difference is AMAZING!!! the OSD 6.5's have always had decent high's and mid range. Now with the Rockville Sub-woofer, I can adjust in as much bass as I want, and let the OSDs handle the mids and highs. This was done for an additional cost of $145. A screaming deal for a subwoofer that really delivers and does an excellent job of filling in the low range which had been basically empty. Connection was simple. As the Rockville is a powered subwoofer, that can be used in a mono configuration, . . . and supports both Line-level and speaker level inputs, I just doubled up the speaker connection on the OSD main speaker. So now one speaker wire pair goes to the passive OSD (as it should), and the other speaker pair connects to the right speaker-level input of the Rockville. Surprisingly there was no detectable degradation of signal to the passive OSD. The rest is setting the subwoofer to the acoustics of your area and personal taste. IMPORTANT NOTE: This Rockville Subwoofer IS NOT WATER PROOF. So if your OSD Patio speakers are on your patio, you might have to seek another option. ORIGINAL REVIEW: Not sure how much more I can add that hasn't been said already, but I can confirm . . . right out of the box these speakers could be a little louder, and definitely need enhanced bass. I was pretty disappointed at first, but then discovered that my Spotify app has a built in EQ which allows me to fine tune the music to my liking. I found the bass lacking so I bumped that up. I found the mid-range sounding hollow like it was coming out of a plastic tube, so I set that down a smidge. I found the highs a little dull (not as crisp as I like) so I bumped that up a bit. They now sound reasonably decent, but they still lose a star because they have to lean on the app EQ to get them this way (i.e., depending on the EQ as a crutch). I can also confirm what others have said. They sound much better once you get them outdoors. I hooked them up in my house just to try everything out before installation and frankly . . . was disappointed. However, I remembered the review stating they were better sounding outdoors, so I proceeded installation with high hopes. In summary, if you're looking for that "gut punching" bass, these aren't gonna get you there. With the EQ bass set pretty high, it's acceptable, but still just pretty good. Overall I'm happy with them, and will keep them, but if I had to do it again - knowing what I know now - I'd probably find something else. ## Frequently Bought Together - BTR150 5.25-Inch 120W 2-Way Weather-Resistant Outdoor Bluetooth Wireless Rock Speaker - OSD Audio - (Pair, Slate) - GearIT Pro Series 14 Gauge 2-Conductor Speaker Wire (100 Feet / 30.48 Meters) CCA Speaker Wire CL3 Rated for Outdoor Direct Burial Use, Black --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/1785566-osd-audio-5-25-120w-wireless-bluetooth-outdoor-rock-speaker](https://www.desertcart.tn/products/1785566-osd-audio-5-25-120w-wireless-bluetooth-outdoor-rock-speaker) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-27*
