Thanks guys. I had previously contacted Fisher and they were a no-go with them.
Still thinking about it, but everyone here is making some very good points. I'm really not having any problems (knock on wood) with my Shures except for the inability to find tips. Maybe I'll look into custom sleeves. Perhaps it is a better choice. Thanks for bringing that up!
As far as the age of the molds.. they're not too old. I had them molded not more than three months ago... so I'm not too worried about that with either way that I decide to go. Lots of good food for thought here though!
Sorry to hear that you've had such a bad experience with Shure Customer Service... that sucks. I will say that I have had wonderful dealings with them. It may have changed, but a few years ago I contacted them with questions about one of their quirky products (PTH) that we were using in our band. I couldnt find much info on them and wanted to ask a few questions. The gentleman I was in touch with was incredibly helpful and even asked if I would write a review for the product after I used it so he could share it with his team. I was glad to. I wrote it, sent it in.. figured that was that. Then, out of the blue a week later I received a box from Shure. In it were a new set of IEM (which I ended up giving to another fella in the band who was hard up for an IEM solution) and 2 PTH units. I contacted them back asking if the shipment was a mistake, but the gentleman told me they were a gift and a way of saying thank you to a customer. Quite decent of them to do and a very very nice suprise. It's very possible that I may have got the good apple in the bunch. Either way, I've always found them to be good people to work with. Sorry that you've experienced something else.
Maybe I'll look into something cheap like the Livewires.. good idea! Where could I find info on those?
