Ok great, so I've decided to get one of the Etymotic IEMs, I'm still deciding between the ER4S, ER4PT and HF3. In the UK the HF3 is going for around half the price of the other two i.e. £85 vs £160. Any suggestions? Isolation is my biggest concern, a well behaved treble and a decent bass response would be a distant second requirement. Considering the price difference which should I go for?
ER4PT = ER4S and ER4P in one package. ER4PT without included resistor plug = ER4P and ER4PT with included resistor plug = ER4S
I don't know why people keep saying this? Did you get a resistor adapter with your er4pt?
"What's in the Box
ER-4PT earphones, 1/4" stereo adapter, airline adapter, 6 pairs of ACCU-Fit eartips, shirt clip, replaceable wax filters, filter removal tool, channel-matching compliance graph, travel pouch, and storage case."
The "T" is for the travel/airline adapter. Not a 75ohm resistor adapter. ER4PT should equal ER4P with airline adapter not ER4S.....
Isolation of the 535 isn't bad, but 10db more with the er4 can be a huge difference as well...
