I had a chance to demo these. They sound every bit as transparent and clear as the Etymotic but there was this really lush midrange that felt expansive and had great separation and imaging. It made me hear so many new sounds in music that I didn't notice previously.
The Dita Answer Truth Edition sounded similar to the KSE1500 to my ears. It also had the detailed analytical treble with a lush transparent midrange.
I found the UM Mason V3 quite neutral and balanced with excellent clarity and spacious soundstage. Perhaps sonic-wise it could be an upgrade in that price range.
I didn't find the universal fit comfy though, due to the 2x16 drivers the housing is quite big. It is probably not an issue with custom fit. It is also built like a tank.
I can't justify however the $2699 for it.
Does anyone have recommendations for an ER4SR/XR cable that's suitable for sleeping on with my face on the pillow?
I've broken countless ER4 cables over the years from doing this. It always frays at the 45 degree angle joints connecting to the driver unit. I've tried the MMCX adapter for ER4P from ebay that makes it a 90 degree unit and I broke two sets of those too.
I got the ER4XR thinking I could use the cheap $10 Shure MMCX cables on aliexpress, but I was dismayed to find out it requires the special type of MMCX connector and the cheapest cables are still around $40-50.
I wear mine if I wake in the night and that's hard on the cables. I'm now able to swap in cables, and am no longer reliant on what can be very uncomfortable adapters, or having stock MMCX connectors popping out of the XR 'female'. ClieOS has really done something that'll improve my quality of life.
Etys are not perfect. What is perfect in high(er)-end audio?
But the fact these little buds offer sound quality that rivals other IEMs/headphones for 8-10 times the price is very f*ck*ng exceptional.
I have found my perfect IEM for my 5-6 flights a year. For this little use I didn't want to spend a lot on IEMs so went for the ER3XR. (I tried flagship ANC headphones and they suck.)
After buying the ER3XR and being this happy with it I might actually support Etymotic by buying the ER4XR even though I hardly ever use IEMs.
