Intouchaccess.com is selling the Etymotic ER-4 earphones for $209 and the the ER-6 earphones for only $99. I already purchased the ER-6’s and they arrived within 5 days through the USPS. If you buy the ER-4s or anything else totalling over $100, then there is no shipping charge. This is the lowest price I’ve been able to find.
