Disclaimer: This special version of Ultimate Ears Reference Monitors has been provided by James. My blog would've been long gone without my friends' continuous support, THANK YOU!
In a collaboration with Capitol Studios, Ultimate Ears developed this custom IEM for studio engineers. The manufacturers claim that the IEM has been meticulously tuned to be flat, in order to match any type of professional recording/mixing/mastering conditions.
CON: Unlike what the specification states, the UERM does not cover up to 20 kHz. Its impedance characteristic varies greatly over the entire frequency spectrum- making the IEM hard to be driven effectively.
ON SECOND THOUGH #6: This is what I said in the previous article: "Is it just me, or the frequency response of the UERM really resembles that of good old Triple.Fi 10 Pro?" Since James has provided a scratch pair of TF10 as well, I simply cut the IEM open for modification, and matched its frequency response to that of UERM here.
