Question: I would like to have these hang off my deck for outdoor use. Can I just use my laptop bluetooth or phone to stream or do I need a amplifier to do so?
Document: these speakers are on my deck. they sound terrific. good but not booming bass, but c'mon these are for an outdoor area. if you want to go to a concert, go to a concert. the bluetooth range is probably 15-20 feet, but i just use my phone or iPad or whatever, set my music, and leave it nearby. no complaints. would recommend. have been thru a couple of really bad rainstorms with no problem. these are a great idea.
We purchased these to use outside on our deck and off the garage. I cannot tell you how very happy and surprised we were with the outstanding sound and clarity that these produce.
Advertised as working with any Bluetooth device, but id did not sync with my android phone. I had to take the time to re-pack and ship back to the company. Very disappointing. To their credit, the company did send an RMA and refund my purchase w/o any issues.
These speakers sound good for the price. They seem well made and come with a good quality speaker cable. So far as I can tell they have a corner on the market of blue tooth outdoor stereo speakers, which seems like an obvious BT application. For me, BT connection is solid within 15 feet or so, and started to get spotty beyond that. They are loud enough for me, but they don't crank up super loud.
Speakers sound just fine and look great. What I don't get is why speakers advertised as &#34;weatherproof&#34; and designed for outdoor use come with an AC power adapter marked &#34;INDOOR USE ONLY.&#34; Wouldn't a weatherproof/outdoor adapter be more practical?
Sometimes BT is spotty, not all devices have BT, so why BT only?A decent alternative would be Lepai amp, blue tooth receiver, and outdoor speakers of your choice. Cheaper (depending on speakers), louder, 3.5 mm jack option, but the problem I ran into is protecting the electronics from the weather. That made the decision to go with these easy, and since they do sound good I'm sure I'll enjoy them.
Used these for the first time yesterday, it was our first nice day of the season, and I am very happy with them. It was nice to be able to listen to my music from my phone while I was on the grill. The speakers perform pretty well and sound very clear and can easily be heard from anywhere in the yard. Super easy to use everything is controlled right from your smart phone.
Bought them for the ease of use for bluetooth to eliminate wiring from outside to inside. i have a droid razr and the volume does not work at all through my handheld device. The volume blasts 100% or mute only. Tried using multiple playback apps and pandora, spotify, etc.
Works great. Mounted them out on the deck by the hot tub. I wish they had more bass range.
I just got done installing these. THey look and sound great. All devices have paired up sucessfully and only time will tell now. If they work like they do in a year or two....You can't really expect much more. Sound is great.
Answer: You can stream direct from laptop, phone or pad.  Amp is built in.
