I've been including measurements in my IEM reviews. But those measurements were taken with my MiniDSP EARS rig. While the EARS is a great budget headphone apparatus, it's far from ideal for measuring IEMs.
So, following Theo Lee's excellent guidebook, I purchased two IEC-711 Clone Couplers to create IEM measurements that can be compared against those from other reviewers using similar couplers.
Pleased with the accuracy of the coupler's results, I contacted Mark Ryan Sall
