    I combined the AR-4i by Fostex with my iPhone 4S to record performances of our locally-touring, alternative rock band. What an improvement in sound quality of our recordings!

    Admittedly, I am a novice in the a/v world, so I searched for inexpensive "hacks" to quickly improve the quality of our a/v recordings to keep our website up-to-date with the most recent clips of our live gigs.

    My iPhone fit easily and securely into the device. I attached this setup to my tripod using only the threaded tripod mount on the unit. In less than one minute from unboxing the AR-4i, I was test recording (I had previously downloaded the free dedicated app to allow sound monitoring on my phone).

    After learning a few basics, I was able to monitor the recording of incoming sound during the gigs using only my everyday "earbud" headphones plugged into the device. I eliminated "clipping" (I just learned that term:) and other sound distortions that had been plaguing our previous recordings. By adjusting the volume and direction of each of the two mics (included with the AR-4i) I was able to capture ALL of our music sound (previously, the bass line was muted or even missing in some recordings, and our bassist really hated that!)

    While the unit is suggested for the "recreational" rather than "professional" a/v user, it has been a valuable primer for me to learn basic audio recording concepts. As my skills improve, I hope to purchase even more sophisticated a/v equipment, and learn mixing techniques. For now though, the dramatically better-than-standard quality of the audio captured from this device nicely parallels our band's improving musicianship and performances.

    Overall, the AR-4i is a light, portable, high-quality, unit, and it is an absolute bargain at its very modest price! I highly recommend this for anyone who wishes that the audio quality of the videos they take could match the (relatively) high-quality camera already onboard their newer-model iPhone or iPod.

    I was thrilled when I finally purchased this product. It is solid in construction and the ability to both stabilize the camera for better video and have more effective audio control (with stereo) is fantastic. Being able to manually adjust the audio level with a small wheel also fantastic.

    However if I wanted something as heavy as this with a steel handle, I would bring along my regular video camera or DSLR! And the cavernous battery compartment to place the tiny AAA batteries is another peculiarity. These issues knock two stars off my rating. It is insanely annoying that the designers couldn't recognize these issues.

    Summary: Excellent product, performs well but on the physical side, needs some rethinking.

                I took it out of the box, threw in 2 AAA batteries and took it with me to an event where I recorded a ton of video in different settings, the audio was so much better. I would recommed this to anyone that is in need of shooting video with your iphone.

                        The Audio Quality is enhanced dramatically.
                        Video capture is aided by hand grip and larger area to hold while shooting.

                              Love my iPphone4 but was underwhelmed with the quality of the audio when using the video camera functionality. The AR-4i (couln't they come up with a better name?)solves that problem. My audio is now so much louder, so much clearer. My posts on You Tube and FB are so much more professional. This little guy is EXACTLY what I need. While it may not be suited for a high end user it is well designed, well crafted, well enginered.

                                  BUT Im not sure the 4S likes that sync cradle...You have to take the phone out to upload a clip...just finding a few bugs...but overall..its worth tinkering with...the sound can be very touchy too...and not every earphone will work...so not perfect but would buy an updated one when offered..they are on the right track

                                  Comments about Fostex AR-4i Audio Interface for iPhone 4/4S & iPod touch 4G:

                                  I made a few short videos of interviews with artists for an art exhibit promotion. It was a good idea but the quality was lower than I wanted. I researched a lot and found out that the quality of the audio of an iPhone video counts for as much as 70% of the experience for viewers. Some form of external mic is essential. The AR-4i was just what I needed.
                                  I just slide my iPhone 4 with the bumper case taken off into the unit and it starts up. I can adjust the audio input and monitor it with earphones. The improvement in audio quality over the built-in mic is astounding.
                                  What I also like is that there are two tripod mounts for vertical or horizontal. I plan on also using this unit with a wireless clip-on mic I have and can easily plug that into one of the ports.
                                  I was testing out the unit in my patio and accidentally left it on the table after removing the iPhone. It rained all night with it outdoors. The next morning I removed the mics and windscreens and laid everything on a newspaper to dry. When I plugged in the iPhone later it worked just fine. It is solidly built and easy to use.
                                  The unit itself requires AAA batteries and are said to last 10 hours. I use a lot of AA batteries but will have to stock up on AAA for this unit. Not a big issue.
                                  I downloaded the free app that goes with it. I can use it to make adjustments. What I do not like is that there are not very complete instructions as to how to make the adjustments and how to maximize the settings for my particular use. I would like more extensive tutorials.

                                        It produces static on a 4S and it disconnects the phone from the network when used with the AR-4i.

                                        Comments about Fostex AR-4i Audio Interface for iPhone 4/4S & iPod touch 4G:

                                        I used this on several occasions with my iPhone 4, and it performed flawlessly. The audio is fantastic. I recently upgraded to an iPhone 4S, and it is not working well. The audio playback produces static.

                                        In all fairness to Fostex, the specs claim that it is compatible with the iPhone 4. There is no mention of the 4S.

                                        There is the capability to update the firmware on the AR-4i. I hope that Fostex can get it working on the 4S as well.

                                        If you're an iPhone 4 user, this device will dramatically increase the audio qualtiy of your recordings.
