AirPhones turns your iPhone or touch into a wireless speaker

But a set of A2DP capable bluetooth headphones can accomplish the same thing... albeit for a smaller distance.

looks interesting but i think i'll wait for something from Rogue Amoeba. Here's hoping for "Airfoil touch" soon.

It works ok. But it's mono. It only streams the left channel.
Set the balance to the right in system preferences or in an app and you won't hear a thing. Why was my previous comment deleted?

Unfortunately it's mono. It sends the left channel to both channels of your iPhone. If you adjust the balance to the right you won't hear anything.

I've been looking for an app like this for a while. Remotebuddy almost does it right but the interface is incredibly limiting.

Example: for playing your bedroom iMac's large music collection on your iPhone while you're out in the living room vacuuming with headphone attached...well the interface doesn't let you have access to your playlists. From what I remember while testing, I kind of had to go through a lot of menus in order to play one song at a time.

SimplifyMedia had a lot of potential for me, but it chokes on my hugh library of songs. If they would only let you limit the collection you're trying to connect to by letting you just sync to a playlist instead of your entire library then the app would be useful to me.

AirPhone sounds really promising for home use. Some times I want to pull up a quick playlist from my room and have it play in the living room when guest are visiting. I was about to set up my Wii to do this but AirPhones might work. The only downside is that it sound like it will mute the music in my bedroom too. It would be nice if I could connect my iPhone to my living room speakers and have the music playing in my bedroom And the living room by having my iPhone connected to the speakers out there while the iMac handles the bedroom.

While I could spend a bit to make this all work out better: Airphones sound like it might be a super affordable option. I'll probably get it as soon as they remove that "muting" the source (iTunes) issue.

Can I stream to both an Aiport Express and an iPod Touch at the same time?
If so, is there a difference in the latency?

I love SimplifyMedia and use it all the time, but comparing this app to SimplifyMedia is not comparing apples to apples (pardon the pun). SimplifyMedia is for sharing/streaming your music media. This app is for redirecting your macs audio output to your iPhone. This means that more than just your music media can be sent to your iPhone. Anything that you could send to your audio output can be sent to the iPhone with this app, such as a web presentation that has audio, etc. While I agree that, due to the lip sync issue, you probably wouldn't use it much for audio output of a video, which limits its usefulness, but maybe things like listening to a speech being streamed in a manner that cannot be directly received by the iPhone.

Odd - I am looking for the exact opposite - something that will allow me to listen to the music on my iphone over my Airport Express - or does that exist already?

"I have larger than iPod capacity music laptop on my mac, I have my iPod sitting in my dock by my bed, connected to my main speaker system (which my mac isn't). I can now play any track from my mac - whether or not it is on my iPod and change tracks without moving from my desk."

Why don't you use simplify media?
