cep
I've used CEP for around 5 yrs. now, with foam tips. Comfort is an issue after 4 hrs. or so, but bearable. My biggest issue is the wire breaking by the earpiece.
I try to be gentle when using, never pulling directly on the wires but no love they break every couple of yrs. requiring replacement, on my 3rd. pair now.
Even with the wear issues I find their effectiveness more than justifies the cost.
