The JH Audio facility in Apopka Florida has been going gangbusters for over 2 years painstakingly engineering and re-engineering the amazing 16PRO in-ears to work seamlessly with their DSP-based headphone amp, the JH-3a. A true hand-in-glove audio tandem, the 16PRO offers amazing sound quality with an open tone and an exactingly precise, yet huge sound that can only be called 'room speaker' like in its expansiveness and massive impact. Employing Jerry's perfectly realized -- and fully patented! -- Digital Signal Processing [DSP] topology, the JH-3a amp can be shaped and sculpted to deliver any low-end timbral presentation desired up to +/-12dB. The tone can go from clean and analytical to warm and rich with beautifully textured, perfectly detailed bass response down to a true, bench-rated 10Hz (!) that must be heard to be believed. Highs soar and sing out to a verified 23,000 kHz so the detail resolution and sense of 'air' around instruments and voices will make you feel like you're right in the middle of a studio take or on stage with the band. Our RMAF 2011 HeadRoom crew had a hard time manning our own headphone booth with these things lurking around the corner! Groundbreaking work as usual from Jerrry Harvey Audio.

NOTE: JH Audio no longer offers JH-3a amp 'retro-fit' conversion procedures on any existing 16Pro in-ear monitors. Customers must purchase this entire 16Pro + JH-3a amp kit as a whole package.
