I have 2 pairs of headphones for sale that work with the Equinox 600 or 800. One is the LS Pelso waterproof phones. I replaced the stock ear pads with gel pads which are very comfortable and fit over the ears better. The other set is the wireless phones from Quest, Wire-Free that work great. They are missing the rubber cover for the charging port. Both sets are in very good condition. I am asking $115 shipped for both sets. I can take a USPS money order or PayPal friends and family. If you wanna use Goods and Services, please add the 3.5% fee. I will ship USPS priority shipping.
