Steven R. Rochlin has posted a review of the Hum Pristine Reference Custom in-ear monitors ($1299) at Enjoy the Music. His conclusions:
“Overall, the HUM Reference CIEMs are extremely dynamic and have the best transparency of any CIEMs here. They may not produce the uppermost and lowermost frequency extremes, yet odds are you might not miss them all that much. A bit of EQ’ing can help to some extent of course. HUM’s Pristine Reference CIEMs may be perfect for sound engineers who are seeking to hear as much as possible within their mix.”
