Re-listing these. I had sold them on AVExchange, but the user who bought them asked to return them when they noticed a channel imbalance that I previously missed. Got them back today and can confirm the channel imbalance- the right side was quieter than the left. My fault for not doing due diligence with them after I received them in a trade. I just cleaned the right nozzle and it seems to have helped to the point that I'm not sure if the imbalance is still there or not, but am pricing low and noting it here. Case, cable and eartips are all non-original. Price includes shipping.
