Can interchangeable filters make the t103z the first IEM that sounds great to everybody?
When testing headphones with multiple listeners—our standard practice at S+V—I've learned that perceptions of a headphone's tonal balance can differ among listeners. Of course, individual taste in sound varies, too.
One solution to this problem is a headphone that can be tuned to the user's taste, a feature we've encountered on in-ear monitors from AKG and Phonak. Both have interchangeable filters that can alter the headphone's tonal balance. But the former costs $1,299, and the latter uses extremely tiny filters that require a special tool to change.
A new company named Torque Audio has what looks like a more practical approach.
