wireless

I have owned these speakers for a about a year. I bought them at a sidewalk sale in my neighborhood in Brooklyn. I use them to broadcast the audio from various satellite channels to where I sit at my computer. The distance is no more than 30 feet so I cannot say how they would function over much longer distances.

As opposed to some of the reviewers, I have had no difficulty adjusting the frequency. I have very occasional static interference but for the most part this is a non issue. In essence, I use them in an urban environment on one floor of a brownstone here in Brooklyn so I cannot say how they might operate in your neighborhhood. I have them set for mono as this this tends to minimize whatever small amount of interference there may have been. This has a slight effect on frequency response but it is not major.

Please note that the fidelity is quite good but it is NOT audiophile quality so it is probably good to take that into account. All in all, I very good product.

I agree with Phillip Hamilton's review. Maybe I'm more sensitive to noise so I can only rate these 1 star. I live in a suburb but I've never overheard anything from baby monitors or cordless phones. The noise really gets bad when someone walks between the transmitter and speaker. I've got one in another room 20ft from transmitter and one in another room 60ft away. Neither is acceptible for very long. The sound is quite good when they're not picking up interference but listening to noise 10% of the time is not acceptable.

I am very pleased with these speakers. As a matter of fact I just ordered a second pair for the school. We use the cafeteria to show videos to two or three classes at a time. I use an LCD projector to enlarge the picture and I place these speakers in the back of the cafeteria so the students in the back can hear clearly.
