MonsterRadioPlay 300 Universal Full Spectrum FM Transmitter MBL-FM XMTR300 (Discontinued by Manufacturer)

When I bought my car I got a what I thought was a cheap $40 FM transmitter. (not this one.) I had nothing to compare it to, it sounded maybe just a little worse than my regular FM radio stations. I thought this was terrible quality, I wanted better. Well, once the cables finally came loose (cheap quality) and I needed to buy a new one I was spending more than twice the amount I paid for that first transmitter. The pros were that I was getting charging and play features in one, however the sound quality on these nearly $100 FM transmitters was HORRIBLE, constant buzzing in the background, very frequent static. I went through a total of three of what I thought was top quality transmitters until I came to this one. Now even though I'm not getting the charging the sound quality is once again comparable to the radio stations and this is whats important.I cannot say for sure, but in my opinion the reason is this one and my first transmitters work through the headphone jack. How the cables came loose on my first one will sure not happen to this one, the build quality is much much better. I was reluctant to buy this transmitter, it took me a while buying others and returning until I came to this one. I hope others will read this and make the correct choice right away.I'll also like to point out one of the other transmitters I had was able to broadcast on 87.9 and below (not positive if that is the correct station) and even those were not as clear as this one.So overall this is a great buy and I can say with confidence as I wait a good period to test out products before I review them. Just don not expect great quality as it is only a FM transmitter not a AUX or USB.

my cd player in my car doesn't work and instead of buying a new stereo I decided to purchase an FM transmitter so I could listen to music in the car. I have owned cheap ones in the past and have found them to be basically worthless - the signal barely would work, the music sounded terrible, the device had to be sitting next to the antenna, etc. etc. etc. I decided I would drop a little extra money to get the Monster FM transmitter because there was no point in wasting money if it didn't perfectly.And this one does. No problems, easy set up, works from the front seat of my car with a back in-window antenna. It also worked in my roommate's car with an outside antenna. The reception and sound clarity are great and it even looks pretty stylish in my cigarette lighter port.It was a LITTLE pricey (I could have purchased a new stereo - albeit a cheap junk one - for a little more) but it matched or exceeded my expectations in regard to functionality and I paid the extra for that purchase so I can't mark it off for that. Basically, if you need an FM transmitter, you cannot go wrong with this.

I had the Monster Radioplay 200 and it got a short in the cable thanks to leaving it out in my car, which turns into an oven in this Arizona heat.I tried a Sony DCC FMT3 since I couldn't find the Radioplay 200 in any stores. Disappointed in the product (way too much static and cumbersome wires) I turned to the net and found Monster's next version of the Radioplay.Just like the 200, this model gives the least amount of static I believe you'll ever find in an FM transmitter. It performs just about the same as I drive through various settings from isolate desert to crowded avenues. I rarely get 'tuned out' by someone else's transmitter, or whatever the deal is that lets someone else's music come through my radio. With the Sony, it happened way too often.The sound doesn't get compromised, either. Bass is still as clear and crisp as your speakers allow. With the Sony, bass caused static, which I think is one of the most annoying things in the history of man.I don't know if its just the unit I rec'd, but the buttons on this one are very flimsy, not nice and tight in their seating.Also, its not obvious how to seek for stations. You're going to have to peek at the manual.Other than those gripes, this is the best transmitter I think you can find.Update - Just like my 200, the 300 has shorted out as well. The unit still gets power evident by the part plugged into the cigarette lighter still lights up. But the short prevents power to the actual FM transmitter part. Again, I left the unit in my hot vehicle...so that is probably what caused the end of both products. But...maybe not. I'm not sure I want to dish out another $35 to find out. Still, this IS the best I've had as far as reception and clarity go...
