Better audio than FM transmitter
928746
This device provides great audio.  It does a much better job than an FM transmitter.

I use this kit with a SONY cassette adapter, for my 4th Gen. iPod, and it works great.  A few comments on this kit:

* I get a full charge on my fully-drained iPod battery in about 1 hour.
* If you plan on using a cassette adapter, then connect it to the cassette adapter plug on the kit, rather than directly on your iPod.  It is a convenient way of shortening cables, and routing less cables to your iPod.
* I experienced distorted music play-back when I set the kit's volume control on a high setting.  I found that it's best to keep the kit volume control at a medium (or less) setting, with an iPod medium-high (or less) volume setting, and use the car's stereo for over-all volume control.

Great sound for the price! Fm radio function is just static though :/

Where I live and commonly drive my car, there are a lot of radio stations, but none of them come in clearly. I wanted to be able to stream music from my phone, and I couldn't resist trying this FM transmitter. I had three problems with it, and found solutions to each. First of all, the reception wasn't very good on the initial station I was using. The key was to use my car's radio to scan through all the available stations in the area, find the biggest gap without a station, and tune the AGPtek to somewhere in that range that put it as far from competing stations as I could. The second problem was that the volume streaming Bluetooth from my phone to the AGPtek and then to my radio was nearly inaudible without turning the media volume on my phone up to the maximum. If I forgot to turn it down after disconnecting, the next time I connected to another Bluetooth device I had my eardrums blown out. The solution was an Android app called A2DP by Jim Roal. It allowed me to set the media volume for each Bluetooth device. When I connected to that device, the volume would be set at the correct level, and when I disconnected, the volume would be adjusted back to my usual setting. It worked great with the AGPtek. The third issue I had was that when I got in the car, I wanted the AGPtek to connect to my phone automatically and begin playing music. Sometimes, it would, but if I was out of the car long enough, it would connect just fine, but seemed to forget to begin playing music automatically. The solution to that was just to push the button on the AGPtek once it connected to my phone. The music would then begin playing right where it left off, and I wouldn't have to take my phone out of my pocket.

After several weeks of experimenting, I just wasn't satisfied with the sound quality of the AGPtek for my use. The most common trip I make is about 40 miles one way, and I go through so many different radio reception areas--none of them very strong--that despite picking a relatively interference-free station, I just wasn't able to get consistent, static-free sound. I'm just too picky about the quality of my music to be satisfied with that. I went ahead and shelled out the cash for an actual Bluetooth-capable radio, but I'm hanging on to the AGPtek so that if I have to drive a vehicle that doesn't have Bluetooth I will still have decent music. For the price, it's a great backup in that kind of situation, and it may be that the area where you will be using it won't be plagued by multiple interfering stations like mine, or you'll be traveling in a smaller area where you can find a good setting for it that won't be interfered with as much.

Works as well as any fm transmitter I've had, USB port is a plus.

I am very impressed with the AFT 100 FM transmitter.  I honestly wasn't expecting a whole lot after doing some research on FM transmitters that I wanted to use in conjunction with my MP3 player.  But this transmitter works great for me with both my MP3 player and also with my car dual screen video player.  My kids love that they can watch a movie and then hear the audio come through the car stereo which is of much better quality and loudness than the speakers on the video players.  We do not live in a metropolitan area and so that may make some difference and also our vehicles all have external antennas instead of embedded windshield antennas - not sure if that makes a difference or not.  Overall, I am very satisfied with this product - it does what it should do and based on my experience does it very well.

It had been some years since I tried an FM transmitter for my music, but this is by far the best. Used to be that even those weak, unlistenable, inbetween radio stations signals would interfere with the thing and make it pointless, but this one actually drowns it out so I can get a pretty clear reception from my device. Problem is, I have to have this thing and my phone turned all the way up, plus have the radio turned up quite a bit more than I normally would. If I were to turn the thing off, I'd get some pretty loud radio static to surprise me. It has the same volume problem whether I use bluetooth or the little auxiliary input on it. Also, it's harder to plug the aux cable in than it should be. I have not really attempted to use it has a hands free phone option yet, but received a call when I was first testing it for my music, and it did not seem to work quite right as it alerted me to the phone call through the car speakers but failed to transmit the call itself that way. However, that could have been because I answered the call on the phone itself rather than using the answer button on the transmitter.

Works a lot better than the more expensive transmitters I have purchased in the past.

A++, excellent FM Transmitter. I would definitely buy again.

I wanted to listen to music, podcasts, and audio books in my car. My car doesn't have bluetooth connectivity, and the tape deck in my car doesn't work, so I couldn't use an audio casette adapter. I read that the next best option is to get an FM transmitter.

I chose this one because it connects to the DC jack. This was so I didn't need to deal with any batteries. I also wasn't sure whether these transmitters have good signal strength when on regular batteries. This particular model has a battery compartment (2x AAA) if you want to use batteries.

I bought this FM transmitter back in November 2012. It is now May 2014. I've owned it for about a year and a half, still going strong. From what I recall, the instructions were clear and had English.

The audio quality is reasonable for what it is, so you have to find a frequency that's relatively quiet and unused (depends on your location). Sometimes I do hear some interference and static, but I've found some frequencies that are pretty good. It's also best to turn up the volume to the max on your device, so your car doesn't amplify the static so much. You can save 3 different frequencies for quick recall.

It's been working out very well, and use it to listen to my to audio from my phone during my commute to/from school every day. It's quite helpful to listen to my audio recordings from lectures over again, either from my digital recorder, or from my phone. The connection is the 3.5mm standard, and connects to my phone or recorder securely, without wiggle.

The FM modulator is OK. The sound from the available FM channel I chose in my area was staticky. I tried some manual searching for a clearer channel, but it was not to be. I know the availability of free FM channels in larger cities like mine are limited so I kind of expected this scenario. At times it is pretty clear. The product will not deliver the same sound you hear on your headphones though.

The transmitter works best if you google unused radio stations in your area for example I used 107.9 FM it works great. It has a little static here and there and it may pick up other radio signals once in a while but it's worth it if u don't have a regular aux.

I added this to my 2006 Volvo S40, and now I can listen to music from my phone over the car's speakers, which is great. It works way better than the FM transmitters I had tried in the past--the audio quality is much better, and it's a sturdier product.

Pros:
This was really the only viable option for me, other than the low-quality FM transmitters, due to the audio setup in my particular car.
It usually works well.

Cons:
Installation was a BEAST. I highly recommend that you take it to a professional to get it installed. It took more than a day to get all the wiring done properly, and removing the interior paneling in the car was a huge pain. Even when we were done, wires were hanging out of various places... It didn't look super great.
Sometimes we get weird distortion/fuzz in the audio. This may just be due to the particular radio channel we picked, so we changed it recently to try to improve it, and it's been working out so far. This usually clears up on its own even when it does happen, and honestly, it's still better than what you'd get from an FM transmitter.
Have I mentioned installation was an awful process? Seriously, use a professional.

I used to have an iTrip for my 1st gen iPod Nano, which always had a lot of static. I knew a few other people who had different transmitters, but had the same problem. After trying to blast music out of my iPhone 3GS for a while, I thought I'd give the FM transmitter another shot and got a FlexPod+. It's so much better. Here's why I like it:

1. It's much clearer. When I listen to music, I don't hear any static. When I listen to talking podcasts, there's just a little bit.

2. Automatic station finder. There's a button on the top of the FlexPod+ that will find an unused channel to broadcast on instantly. Very handy if you're driving somewhere else and don't want to futz around finding new frequencies.

3. Power. My iPhone gets charged (albeit, slowly) when it's plugged into the FlexPod+. I can listen to internet radio, use the GPS, and still have more juice in my battery than when I started.

4. Swivel. The FlexPod+ has will rotate in a few axes, so it's easy to orient it in a natural position. It's really easy to swivel from portrait to landscape or vice versa

5. Handsfree calling. If you plug in an additional headphone jack (included) into the FlexPod+, you can use your car's audio system as a handsfree system. It's clear on my end, and people on the other side can't seem to tell they're on speaker.

6. Price. It's cheaper than the kits they sell at BestBuy, the Apple store, etc.

7. No weird dialogs. Some FM kits aren't validated (I assume by Apple), so it pops up an ominous message when you plug in. Not this kit. It's all smooth sailing.

8. Support for other devices. The kit clamps onto the iPhone, so it's not made for *just* a specific model. In fact, you can use non-apple audio devices via the headphone and USB jacks too.

I'm a pretty picky guy, but I'm totally satisfied with the FlexPod+. I recommend it without any reservation.

For days I researched which FM transmitter to buy.  After everything I read, I decided to wait for Kensington to release this one. This transmitter was also highly rated by Ilounge.  Bottom line...It sounds better than my FM radio.  Absolutely no static! I love it.

Before you buy make sure one of the frequencies that this device transmits on is free from interference from other stations.  If so the sound quality is equivalent to FM radio, but if not you will likely hear scratchy static especially during quiet songs.  I set my mp3 player on my dashboard so the transmitter is as close as possible to the radio which improves the signal.  Also make sure you have the sound turned all the way up on your player.

This is the best FM transmitter I've heard.  The vocals do tend to break up, especially the "S" sounds, but it rarely gives me any other problems.

This has to be one of the best gadgets that I've come across in many years.  I've always wanted something to wirelessly transmit audio from the TV.  The Bluetooth solutions don't work well because of the delay.  I remember seeing an RF based device, which was simply a transmitter with RCA inputs and a battery powered RF receiver with a headphone jack.  Pretty simple, but that was about 15 years ago and I regret not having bought that.  This is the next best thing, but in many ways better, specifically for TV use.  It's much more pleasant having a speaker near you rather than blasting across a room.  It's not the prettiest thing ever, it looks like a cheap mini boombox.  But it does work well, the sound is synced without delay, the charger takes a while but lasts for a day, and the aux in is a nice plus.  There are also tone controls which are appreciated.  Personally I was looking for a more portable device, but this works well for it's purpose as a TV speaker.

If your setup is perfect - ie the transmitter to antenna distance is less than 3-4 ft, there are no interfering radio stations, and the volume on your audio out device (cd player, mp3 player) is at maximum - you get FM radio sound quality.  However, as the distance from transmitter to antenna increases or if you're in a region with a lot of interference, static overwhelms this transmitters low output.  A lot of times I needed to lower my car's antenna to hear anything at all.  Additionally, the power button is not only easy to accidentally turn on, but there is no auto off feature and the "on" light is not bright enough to warn that the device is still on.  On my last road trip the device was accidentally turned on and the batteries died.  I won't be buying replacement batteries for this device.
