Hi. I own the above RHA earphones of which one side has just for no apparent reason stopped playing. I like the sound of thr RHA earphones but they do seem to suffer from build quality issues of which I have read about on various forums. I dont really know what to do. I also own the Soundmagic E 10 earphones but have read many good reviews on the newer E10S model could someone please guide me as to which model I should choose I can get another set of the RHA ones at a reasonable price but worry that they might fail or do I go for the Soundmagics. Thanks in advance for any suggestions.
