Best Workout Accessories for a 6th Generation iPod Nano

So I bought an iPod Nano green a couple of months ago and am loving it. I've got all my music on there and some podcasts now. Awesome. I listen to it on the way to work, at work, on the way home… even in the car.

For the car, since there was no Bluetooth for the Nano, I did a bit of searching and found this really compact Bluetooth dongle from Kokkia, the i10s Bluetooth Adapter. You pop it in the connector for your USB cable and boom! Works like a charm with an FM transmitter.

So this brings me to the gym now. I've had several wired headphones over the years and as always, at some point, the wires get caught on something. After a few times, it usually results in the headphones no longer working or that annoying only one ear bud working syndrome or even worse, both working, but the music keeps cutting out because the wires have been yanked or caught on something way too many times.

At work, I have a great pair of Sennheiser RS-130 wireless headphones. I love them, but they're a little big for the gym. Plus I'd have to have the base plugged in somewhere… which brings me to Bluetooth headphones for working out.

I would really like to find a decent pair of Bluetooth headphones for working out. So far the ones that I found that seemed to have really good reviews are the LG Bluetooth Stereo Headset HBS-700 and the Sony Ericsson HBH-IS800 Bluetooth earbuds .

Anyone out there own a pair of these and love them or does anyone have any recommendations for a good pair for the gym?

 

Also, I've been looking into arm bands. I'm looking for one that fits someones arm who works out. I got one free with a clear case protector I bought but it's so tight on my arm (I'm no beast, but my arm is between 15.5"-15.75'). I think it was designed for 1970s supermodels. Basically I'm looking for one that has some elasticity to it, will allow the iPod nano 6th generation to clip on easily and to also have room for the Bluetooth dongle above without it breaking off I ben my arm.

I found these ones but still not sure which one to buy, if any of these:

The Griffin armband seems to have some elasticity to it from what I can tell in the picture, but I'm not sure if the Belkin does. Any other suggestions or do you highly recommend any of the above?
