This product delivers.
I, like many, have experienced much frustration with FM transmitters. They are all useless.
Except this one.

I enthusiastically endorse this product (shame it’s not in stock right now as I type this). I purchased the iRiver AFT 100 and the Belkin TuneCast II after buying this product, and was able to do a direct comparison. I live in the San Diego area which is flooded with FM radio stations where it’s difficult to find an empty, available radio station. My best bet with each player was 88. 1, which I used to test all three products. The TuneCast was first up: It made a horrible sound as I plugged it in, scratchy and staticky which then faded into the music. Overall, it sounded like a semi-weak radio station. The iRiver was a little less weak, but still very scratchy with an inredible background hiss that persisted even as I tried every volume and position combination. The only product that created a very crisp and clear sound was this Monster Cable Transmitter. It’s even powerful enough to overide live/powerful stations (though with some static) and at best sounded very similar to my CD player. I am so extremely satisfied with this product and so completely bummed out about the iRiver which from the bulk of its reviews sounded like a champ. It’s not, it’s a chump. The Belkin product has mixed reviews, but I have a friend in San Fransisco that says it works as well my Monster product there. All in all, thumbs up for the Monster Cable Transmitter for its shining reign over the other two “top rated” products.

This is the BEST product of it’s kind. Unfortunately, that’s not saying much. Unless you have a tape deck in your care or you’re willing to drop about 4 bills, an FM transmitter is the only universal tool for hooking up your mp3 player to your car stereo. We live in DC, and considering that the radio waves are pretty crowded here, the transmitter works very well. There is some fuzziness between songs, but we have found a few stations that offer mostly good quality sound. It is essential if you live in a metro area to purchase a transmitter that allows you to use any station. However, in order to change stations you must first save it as a preset station and then move to that station. You can’t just push an up or down button and stop on a station you want to use, you must first save it. This can be annoying and almost impossible if you are driving. Despite all this, I would recommend this product specifically for anyone looking for an FM transmitter. Trust me, this is my third one!

Monster RadioPlay 300 Universal Full Spectrum FM Transmitter
I was searching for the right FM transmitter for our mp3 players. While visiting my family, I learned that my brother recently bought the Monster RadioPlay for his IPod to use on…

I bought this item at the local Circuit City a few weeks ago and I must say this was one of the best investments for my MP3 player I’ve ever made. I like the fact that you can tune this transmitter digitally instead of using a wheel and having to “guess” what station you are on. I have the transmitter set to 3 stations: 88. 1, 88. 3, and 88. 5. I even set my car stereo to these stations as well, instead of the local radio stations! Sometimes I have to switch channels when coming into a busy area (I live close to Memphis). It’s VERY nice having the option of listening to my MP3 player when I’m in the car instead of all the garbage the radio stations play.

Good quality for the price
I bought this to replace a combo transmitter/charger. This one does not give off nearly as much static as my old transmitter.

Good Product
I received this transmitter about a month and a half ago and I am satisfied with it. I was just happy that it worked with my Sony Walkman Mp3 player.

Great value!
Works great! Live in metro Salt Lake City and have no problems finding a station that has no interference. Huge plus to be able to pick any frequency. No cons for me.

FM Wireless Universal Transmitter
I am pleasantly surprised by the performance of this item. I had some trepidation after reading the similarly negative comments on a variety of these wireless transmitters…

Monster RadioPlay 300 Universal Full Spectrum FM Transmitter (MBL-FM XMTR300)
It’s ok. It works, but not to my liking. It does work better than another much more expensive one I tried, but still to much static. Probably not going to use it.

Works Great!
Great product – works well when traveling in the car with my Mp3. Only downside is hunting for radio stations to tune in when traveling to different areas.

Horrible reception
Reception in the car radio from this Monster cable was horrible. One station presets were better the others, but it was not worth the $20.
