Thanks for comparing with the ER4XR. I like my ER3XR, and was wondering if the ER4XR was worth the extra money. I'll probably stick with the ER3XR if the differences between the two aren't dramatic.

@earplug - I don't think the difference in sound alone is worth the jump in price, ER3XR and ER4XR are quite close in my honest experience, when it comes to sound. ER4XR does have that premiuum feeling to it compared to ER3XR, but as far as sonics go, they are a bit close to be able to recommend ER4XR over ER3XR...

Since I believe you have reviewed both, can you tell me how these compare tot he iBasso IT01s? I have a pair of HF3 for Ety, and wanted to either get these or something new - someone on the forum here suggested the IT01. What are your thoughts?

@Maestrophil - I have both, but... They have nothing in common ER3XR is really tight, really textured in the midrange, has a really forward midrange, they have very little bass and very little treble, with a really fast bass, really fast midrange, and really fast treble, really revealing, and really detailed, but really dry and not overly friendly, they can be very fatiguing, while IT01 are pretty much the other way around.

@Maestrophil Where ER3XR is Midrange forward, IT01 is warm, with a forward bass and treble, and a recessed midrange, IT-01 has a much large bass, slower bass, slower midrange, slower treble, with the midrange being not as forward and detailed, but neither as fatiguing and aggressive, IT01 has a much sparklier treble, with more emotiona and emphasis on the highs, and overall, IT01 feels more versatile, unless you really like Ety's signature. Also, It01 is much less expensive AFAIK

Thank you very much. Your description is helping me lean towards trying the IT01s. I mean my HF3s still have life in them, if I want to hear a bit more of the Ety sound (though not as nice at the ER3). The iBassos are much more friendly on the pocketbook - even with a good price, the ER3XR I found were 50 bucks more.

I just want to feel like the iBassos are an upgrade for my from my old HF3s. . Guess I should stop being a baby and just buy them already!

Thanks again!

@Maestrophil No worries! I hope the choice brings you lots of fun!

Hey I'm not an Audiophile, but after a week of use something, I'm suddenly Finding harshness/ piercing treble in the vocals, from Rock songs, like Dangerous Night/ From Yesterday/ Closer to the Edge by Thirty Seconds to mars.
Alone Together/ End of Time by Westlife and some EDM Green Day songs. is it something to be concerned that is it due to Driver issue or is it normal?

@msvrthexkid - That does not sound normal, especially if it happened at once. Seems to me like the acoustic filter in the bore tube got lost somewhere, would send in for repairs, or check if the tube seems empty / lacks acoustic dampener
