Samsung M3500 Mono to Stereo dual BT headset Review

Average Reviews:

(More customer reviews)This works for phone calls, but not very good for listening to music or podcasts.
When used with my iPhone 4 it says it's connected after a couple of seconds, but if you start playing audio it doesn't play immediately. It takes 30-60 additional seconds for the sound to play from the earpiece. To make matters worse, the iPhone thinks it's connected and playing so it advances it's counter and you end up skipping over 30-60 seconds of content before the sound kicks in.
Note that this doesn't have any kind of audio controls on the headset. It has up/down volume buttons and a button for answering phone calls. There are no buttons for changing tracks and not even a play/pause button. You have to do all the audio controls on your phone/device.
Also note that the plug for the stereo headphones is not a standard jack. You'd need an adapter (assuming they make one) to plug in your own headphones.
The dual device connection feature seems intended for use with an audio/music source and a phone. It doesn't do anything useful when trying to use two audio sources. It doesn't auto detect which one is playing and you can't easily switch between them.
On the positive side, range was decent and it had very good resistance to interference from other wireless devices.
UPDATE: The problem of being slow to connect and not playing audio immediately turned out to be a problem with the "dual port" mode used for connecting to two devices at once. It was probably trying to find the other device, which wasn't turned on. I turned off the dual port mode and now it connects to my iPhone and starts playing audio very quickly.
I found another minor problem...when listening to audio iPhone, hit the talk button to activate voice control, then place a phone call. When the call is done, hit the talk button to hang up. The audio does not resume playing.
