Question: Can this be connected to TV and home theater system
Document: I needed an auxiliary speaker for one of the patios at our house. Running speaker wire was impractical for the setup, and Airplay/bluetooth speakers were too unreliable for consistent sound. I had tried 900mhz speakers before and had been disappointed, but purchased these thru Amazon Prime reluctantly. Glad I did. Perfect for my needs. Simple set-up, connected with my home theater thru the earphone jack. Consistent connection, good sound- just what I needed.
Take batteries or plug them into an outlet. Use them wired to your device or wireless. Plug the transmitter into your TV, directly into your home stereo, radio or computer and receive your sound with minimal interference or crackling.
I have other brands of 900 Megahertz frequency speakers (which have a far better sound than Bluetooth for the use on home surround sound and patio for music thru receiver or home theater) but the ARs have a better base sound which adds a lot of dynamics  to your listening experience. I still have and use my pair of AR 2AX speakers, which are to me the best speakers ever made. AR makes quality sound.
I am rarely disappointed in products purchased through Amazon. But this speaker is horrible. I have spent time, over the last few days, buying cords, cables and adapters. The transmitter would not transmit a signal no matter what I connected it to: my phone, my Kindle, my TV or my Bose Radio/CD player. I changed the channels, gave it time, and stood on my head.
I had been following this product for awhile now (previous version) and then saw this one come out and at a great price. After reading other reviews I bought two. I'm glad I did. I think one would work out ok but with two the sound is pretty amazing. I have them set up outside around the pool and even with the noise of the pool the sound is great. I have the receiver connected to my Apple TV so I can control all of the music from my iPhone.
The sound is terrible and the volume was very low. I'll need to try a different speaker system for my patio.
This is a fun item to add to my home. It works very well. It's attractive and blends in to my decor.
Wireless my foot...... This item NOT worth the price or time. Also can finf at Home Depot for 5 bucks less if determined.
I purchased these (2) to put on our boat and connect to a XM Onyx system.The boat is out of the water, laid up for the winter.As soon as we can get back on the boat I'll let you know.
These speakers were a gift for the dad. He's very challanged when it comes to technology. Not only did he manage to them speakers connected and working, they have exceeded expections. Due to the fact that the speakers work so well, we bought 4 more, in addition to the original purchase.
Answer: Yes, you can connect the portables to any audio output, typically a classical RCA plugs available on most TV or home theater systems. In fact I have them connected to my ONKYO NR 808.
