I got a pair of these from JBHifi when they were around $150, some of best sounding wireless ones i have come across (and I have a few of them). Ok for gym but I did find that they fall out of my ears if i am running.
JBhifi have them for $250, Noels have them for $200 so $89 is a really good price
