My SM3 Mk2's shell has developed a severe crack meaning that I will need to return them for repair. My previous experience is that Earsonics customer service is pretty abysmal so I am not expecting miracles with the turn around (I emailed them last week and have had no response yet) Are there any other reasonably priced - up to £100 - that I will be able to use with my SM3 custom earmolds. I need them to do my job which involves long periods of critical listening. I love the sound of the Earsonic SM3's but the build quality is pretty awful and they don't have the support backup for what is a potentially great product. Many thanks for any suggestions.
