Etymotic ER4SR

Etymotic ER4SR

Voyageur
Still the IEM king
Pros: Clarity, Resolution, ADSR
Cons: The fit can get sore after a while, Bass takes massive hit if the seal is broken
Got these as a upgrade when my ER4PT cable broke. Never expected these blow me away despite being DF flat and BA based, But after owning them for 2.5 years. I keep getting surprised at how detailed they are when trying past albums in my collection, many sound like if I was given a remastered version.

Never understood the "Single BA" claim since the bass goes super deep and the super fast decay really helps with keeping up with fast metal/electronic. While any dynamic headphone seems hit a wall and the bass just sound like a muddy mess. With EQ done you can make fit closer to Etymotic target, 2.7db at 7.5KHz & -2db at 1.6KHz really opens them up further. With 6db bass boost it dosen't hurt the clarity it just adds more meat and sounds more stable than the ER2SE with same boost.


Total steal for a sub $500 Universal IEM.

The ER4S & ER4SR respond well with the 7KHz area boosted by +3db, On some metal/Electronic you can sense the 7K dip. But beyond that it the best flat IEM I've heard regardless of price. I like the S/SR tuning more than the XR tunings which can sound muddy and unclear, The ER4SR sounds full assuming a the seal is perfect.

All this on a IEM with a single BA set up.

Yup, accurate assessment. I am sold on balanced armature drivers. To my ears, they sound just right. It has the natural organic sound and you're 100% correct. Mids and halfway between sub and bass hits hard and they all decay just at the right time to produce a really pleasant sound for my ears. Etymotic should show a 3D representation graph of they BA based IEMs that not only shows the frequency response (frequency domain) but for time domain as well.

Even when EQ'd to bassier sound with Mids/treble tweaks the ER4XR blows ER2XR & other DD gear out the window with detail/speed/etc that common on Planars. I use 4 ~ 6db 105Hz low shelf on the ER4XR It sounds like my past IEM's but somehow the ER4's quality/detail still shows through untouched. Single BA was never the issue It that Etymotic never made anyone realise how strong the drivers were, The 4XR THD was annoying how It became a meme when even Crinacle knew It didn't affect the performance.
