Just called Etymotic CS to inquire as the status of my ER4 repair and it is currently being evaluated. Those who are CONUS and choose to deal with Etymotic should feel worry free doing so.

Just checking in with my 1.5 year old pair of ER4PT. I recently tried a set of the P Series tips from Comply and I did not notice any change in sound but they are significantly longer than their normal tips. I will trim down the length the next time I need to switch out tips. I will be catching...

The Aspire should work out nicely, I started with a run of the mill ego kit and Kanger T3s back in 2012/13. If I were starting over again I might grab up the Joyetech eGo AIO because the biggest factor in quitting smoking for a smoker is an easy to use alternative. APVs complicate things...

Have you done a factory default reset since upgrading? I was having freezing issues and random "glitchiness" but since the FDR the only thing that has not improved is battery life.  I only have anecdotal experience with battery issues, if I swap batteries (1 from promo, 1 from LG sale, 3...

WOW! Pdibs,  Sunboxes, Woodvilles, Tmods, and rare italian BFs also!

100% agree. What music player (app) are you using as well? I found that even when I was utilizing the HiFi DAC in normal mode the SQ was night/day vs no DAC or previous phone(LG G4)

Been having issues with both battery life and freezing, so I bit the bullet and am doing a FDR...fingers crossed all this is worth it.   Recently got the Beyerdynamic DT 1770s and the headphone pairs very well with the ESS Sabre. Now I need to decide on making my own portable cable or creating...

Welcome, I expect you will become quite popular very quickly. Cant wait to hear/read more about the ER4-SR/XR.

I think this means the newest iteration warrants a separate thread (since other than dimensions so much has changed) to alleviate future confusion...

I used Etymotic since they sell the plastic style filters, means they are usually one time use but ensures that I can assure that the nozzles will not be damaged which "can" happen with the cheaper metal ones from mouser.

IIRC the gain selection is based on the ESS Sabre 9602c and not user selectable. Creating a work around defeats the purpose of the entire chipset implementation...   I ran into a similar situation with my RHA MA750i not being able to reach desired volume (due to inline mic/controls no fault of...

The dac fix app only activates the ESS Sabre during playback for apps not originaly compatible, MM helped to impliment dac access to more apps without 3rd party intervention but none of that deals with the gain selection of the amp. Not necessarily helpful but I think some clarification is needed.

Welcome,Tox7o7, the Eytmotic ER4 appreciation thread is located here(link) and can suggest a number of great amp options to suit your needs.

ARGH, well I will finally have some time this week to go and demo the Custom Studio (plus they are now in stock) at my local Guitar Center and now looking into the DT 1770s IDK which I like more:   Custom Studio "Bass" sound slider (but if the DT 1770 sound better than the sliders could be a...

I have a question for those who use the Comply T100/TX100 tips, since the tips fit so deep in the ear canal does that mean I should run a size smaller than I would normally use with a shallow fit IEM? While I understand that they sell kits with S/M/L, I would prefer to buy a single size since in...

You are correct. I had seen their Silver Plated OFC and remembered it as being OCC wire, my apologies. At $1/ft though I am hard pressed to find fault in BTG for not having an OCC option.....

BTG Audio. EDIT: BTG-audio.com does not have OCC as Hisoundfi desired but I would like to leave my original suggestion of BTG Audio due to their great quality, price, and customer service.

Original transducers too?! I would imagine the cable would need servicing since then but if the transducers are 1st run that is amazing! How low are the SerNos?

    I have adjusted my original post to reflect the info you provided ClieOS. Thank you again for saving me in material cost and shipping times just to find out it is not viable. I thought maybe if it was close enough I could simply use the pins from the Ety adapter and modify the FitEar...

400+ pages and a week later I NEED THESE! (sorry for shouting but if you had your ER4s in you probably didnt hear me....) Since I almost never get to use my rig in an ideal listening environment I know that the cable will be a certain upgrade. Missed out on ClieOS awesome cable service and I...

The fingerprint scanner and bluetooth fixes with the update represent the gripes of the masses, I also believe that Marshmallow will come before the DAC/AMP fix (if at all due to third party app compatibility). The current fix seems more than sufficient for those needing to use other music...

Not sure about every version but I know that the Verizon VS990 does not have smart options available.

WOW, that was a roller coaster of 90+ pages to see how polarizing the v10 is among Head-Fi. My current pairing does not allow me access to the high impedance mode (RHA MA750's @ 16Ω) so although the DAC/AMP sound amazing I am falling short in the volume department by probably 5-10 values...

This video(@2:57) also compares them to the Custom One Pro's as well but briefly mentions the DT 770's as being closer in sound signature.   Not much being said about these and I might be heading to Guitar Center to try and see if I can hear these with my own source. GC has them for 200USD...
