The Jabra A125s is pretty good. Pairs easilty and it's onboard battery means that it doesn't drain iPods battery. However some major issues prevent this item being great - and the more expensive Sony BT transmitter is a better long term and overall investment.The MAJOR issue is the lack of the securing 'teeth' on the dock connector. This means a slight tap can cause the unit to come loose. Annoying when you have the ipod in a bag or something. When using the unit i had to put the ipod and transmitter in a camera case thing to keep it together.Which brings me to the size of the unit. Although it is very light and feels 'hollow' the large size of the item means that it doesn't fit-in with a lot of ipod classic cases (the Griffin Reflect is the only case I have that can accomodate it) Even with the battery I think it's too big since it feels like lot of excess plastic.True the onboard battery means that it doesn't put a drain on the ipod but it means its another thing to keep charged.The Sony's transmitter does way with this and to be honest even if it doubles the power usage, an iPod classic would still run for about 10 hours which would probably outlast the bluetooth headset/headphones you would be using.But atleast I know my BT transmitter is always ready for use.The size also doesn't help the unit from coming loose!However I can't falt the Jabra on price. It is cheap - with out being cheap - I just wish it had a more secure connection. I ended up buying the Sony transmitter as well because of the loose connection.
