Heir Audio Tzar 350: High Impedance Ivan

A couple of months ago, I bought the Heir Audio Tzar 350.

Having bought the custom Heir Audio 4.A just a year ago, I was very satisfied with Heir Audio’s level of build quality and customer service, both amongst the very best in the high-end portable audio industry. Their push for high-impedance IEMs was also very unique, and something that I’d been hoping for.

The ‘Tzar” line of Heir Audio universal in-ear monitors comes in two different flavors: the Tzar 90 and the Tzar 350. Since the Tzar 350 is the higher impedance version and the one noted to be the flatter of the two, I decided to purchase the 350.

Rant: Ultrasone’s Irritating IQ

For some time, I’d been bound by morbid curiosity to try the Ultrasone IQ. It has been panned almost universally even before it came out, and today, I shall add further insult to injury. About a month ago, in a show of insanity, I assailed aural cacophony on my senses.

You guessed it. It is bassy and sibilant.
