Sennheiser IE7 for trade. Interested in Westone UM3X only at this time. Willing to pay $$$ for the difference. Trade offers in the lower 48 states only due to 2-way shipping. IEMs are in excellent condition with original box and accessories. I will post photos when I get a chance. You can also e-mail me at email@example.com and I will send pictures via email .
