    That makes sense. Can’t you just buy a 3rd party adapter with similar ohms with the same effect?

    Just joined the drop for the ER2XR/SE. For anyone who's interested, it's at this link.

    Just out of curiosity, did you end up finding something that worked for you?
    I'm in a similar situation with my ety's :) (not my main driver but I'd like to really give these a chance some day)

    What is the expected sound differences between the ER4XR and these new ER2 variants? Big price difference between the 2 and 4 series :wink:
  6. manthisis
    Yeah! The triple flanges ended up breaking in. Also the small Shure olives work

    This is one of the rare occasions I'm spending money on something that I haven't got the slightest idea about. And this being the first DD IEM from Etymotic, there's very little information about it anywhere, so I honestly don't know what to expect. I'm hoping for a nice surprise in the bass department :fingers_crossed:, but I don't expect the overall quality to beat anything in the ER4 series.

    Gotcha - thanks. I went ahead and ordered the ER2SR. I guess that like you, I am hopping for a little warmer lower end :wink:

    not the first DD IEM. etykids, MC5, MK5, HD5.

    Btw, have you guys tried ER4XR or ER4SR with Sony's MUC cable?
    I see normal 'straight' mmcx cables won't fit ER4XR because ER4 series need angled MMCX.
    I think Sony's angled MUC mmcx cables for XBA series may fit ER4 series?

    I like sound and build quality of Sony's MUC cable... 4.4 balanced, 3.5mm, dual 3.5mm balanced are all great.
    I want to know if they will fit ER4SR.

    I ordered a replacement 10 pack of the baby triple flange eartips. I swear the ER4XR is somehow getting better every day for the past 2 weeks, and I want to keep themem going. @ClieOS 's note to ensure normalized pressure in the ear canal is probably the most likely cause, because I do distinctly remember at times putting them in, and feeling pressure in my ears like I had a cold.

    ER4XR going strong after 2.5 years, for those concerned about durability btw (Third birthday is October 31st, cake??)

    Re the earlier post on ER4s current (2019) amplification options

    Unfortunately, it turns out that the Alo RX does not drive the ER4s at all. The output is very quiet via the Ipod's 5.5 3.5mm jack (already amplified via the Ipod's internal amp) and very very quiet via the 30pin signal out, practically unusable. In both cases any dynamics / soundstage are gone due to low volume levels and it is impossible to assess the sound quality.

    With the adapter out of the way the impedance drops to 27Ohms (turnign them into ER4P) but you still have to drive the earphones at close to max level on the pot which creates a more practical volume level but signal distortion kicks in. ER4P option is also not the sound signature I prefer so it is not something I would be willing to compromise.

    Alo RX is a beautifully designed amp but really only suitable for the really low impedance IEMs (below or around 10Ohm perhaps?; even 27Ohm seems too much) even though the manufacturer indicated that it would have no issues with driving them. Nope. Definitely not for ER4s.

    Back to square one, with three options: Fiio A3 or A5 or Nano Ican. I did test the ER4s with other amps I have, a Yamamoto HA02 amplfier (rated at 300mW @ 50ohm) and Desktop Konnekt 6 audio interface on my PC and both improved the ER4s sound. Konnekt 6 being the better match still so I will use it as a reference point.

    According to Desktop Konnekt's specs sheet it is rated at 200mW at 40Ohm load and 93mW at 600Ohm load. ER4s are rated at 100Ohm.

    I can't find an exact match across the current amps but Fiio A3 is probably the closest match to the konnekt (if looking at specs sheets only): Maximum Output power: 450mW(16Ω); 270mW(32Ω).

    The A5 spec's on the other hand give 800 mW (32 Ω) and 150mW(300Ω), which might be an overkill(?). There's also Nano iCAN’s amp that produces 150mW of power at 32 Ohms which indicates it is slightly under-powered compared to A3 and Desktop Konnekt.

    What do you think, is my logic correct?
