Head-Direct is bringing some new products to this year CanJam (Head-fi.org annual meeting) at June 15th in Chicago. Apparently one of such products is the limited production RE-ZERO that is designed to be driven in balanced mode. Not to be confused with the current second-in-line RE0, this new model has a lower impedance, said to have better bass performance and designed to run straight from DAP (normal stereo 3.5mm jack) as well as balanced source or amp (with included adapter). Also, being a limited edition that celebrates the 3th anniversary of Head-Direct / HifiMan's RE-series in-ear line of products, the quantity is set to just 1000 pairs, at US$99 each.
