Question: Can I watch a movie on a MacBook Pro and send the sound wirelessly to these speakers?
Document: NOTE: This review and rating is from testing the speakers ONLY with Apple products for device setup and Airplay wireless audio.I found a good deal on these A1 models a while back and bought several (5). Using iTunes 11.1.1, my Macbook Pro and an Apple Airport Extreme Wireless Router (802.11n - dual band ), I can drive multiple speakers (3 speakers and two Apple TVs so far) simultaneously wirelessly from iTunes on the laptop.
I only gave this product three starts because, even though they sound pretty good for the price, I had to dig around the web a lot just to figure out how to make them work with my HTC phone, MacBook Pro, Windows PC, etc. So buyers beware: it's not trivial to set these up. Once you figure it all out, they work fine.
Works best with AirPlay compatible Apple products. Having said that, these are very nice speakers for the price, they have a crisp, clean sound. I have mine in a living room area that serves as work area and they sound great.
Even using two speakers side by side, the sound was in sync (one test, do not assume this will be the case), but thats not necessary since I have them separated in different rooms. I can also drive them together simultaneously from the laptop with my AppleTV. I have not tried more than 5 devices at a time yet.
I tried every way in the manual to connect this device to my iMac. None worked, and each took several minutes to attempt. After 20 minutes on hold with Pioneer, their tech had no new suggestions, then hung up on me in the middle of a question (and I wasn't being rude to her!). Complete waste of time. I can't even review the sound on these speakers because I couldn't make them work!! !
Should have had Bluetooth capability. I purchased three speakers; one A1 and two A3's. I've tried these speakers in every way allowable and the ONLY way they play seamlessly is when connected directly to the device. I've added all the ports addresses to my wireless router and still there is the interruption of sound. Additionally, the apps such as Pandora, etc. have the same problem losing signal. I have other wireless devices that work 100% seamlessly, no lost signals, no interruption of what you are listening to.
I have never owned a product by Pioneer before and wasn't sure what this product would be like. I was looking for an airplay speaker for a reasonable price. This speaker was far better than I expected. With only two 3" speakers I did not expect much but this thing really fills the room with sound. Really good bass and clear midrange with good highs. I expected only adequate sound and more of a midrange speaker. This is really great for multiroom sound as well as a main speaker.
Setup was a breeze!Go and watch the video at Pioneer...piece of cake!Turn it on, press the correct button, hook up your iPhone and it automatically connects to your Wi-Fi.Airplay is perfect!Sound is great!The best solution at a great price. !Bought three for Xmas gifts!Thank you Pioneer for a great deal!! !Here is the link: [...]
Spent too much money  Lastly, the one good thing about the speakers is the sound itself when you finally realize it doesn't do what it says and just plug your device to one speaker at a time.
Overall I'm happy with this speaker. I agree with some others that it might be a bit bass heavy but not overly so. It was fairly easy to set up. Like the Boston Acoustics I purchased I found it easier to use my Macbook Air to set it up instead of my iPhone. This speaker is lightweight but a bit blockier in appearance than the Boston Acoustics. It's not a deal breaker though as it's going in my daughter's room and she liked it.
Answer: It depends, if you watch through iTunes then yes but other than that I don't believe it works with web browsers.
