I have some really cheap wireless ones, similar to the ones others have posted in here. Only think I hate about them is they are only around 5 hours of battery life which is ok if you are doing some routine tasks but suck if you are going to be listening to them all day during a normal work shift.
They are nothing to write home about in terms of quality but they are no worse sounding than the normal ear buds you get with a new apple or android phone.
I used to use them for mowing but got tired of forgetting to fully charge them so now I just use a cheap set of wired ones for mowing.
For me...I just can't bring myself to over pay for a name brand ear buds that the quality is not really so much better to warrant the price especially since I will normally be listening to an mp3 player or phone where the MP3's are not even the same quality as if you were listening to a CD player.
