Etymotic ER Series 2.5mm Balanced Cable, Black

My FiiO M11s sounds best driving balanced phones. This cable allows me to use my favorite Etymotic IEMs in balanced mode for a great optimized combination.

Turned my etymotic into balanced output. Very handy. Also sold by etymotic but long wait times.

I thought I give these cables a try. I bought it directly from Etymotic at full price thinking it was worth it. I plugged it into my Astell Kern AK120II's 2.5mm balanced input jack. There is major issue with this cable. For one, each independent wire to sleeves are not aligning properly so any slight movement will cause signal static and drop outs. So it would not be feasible to use with a portable device while you're moving around. Forget about attempting to use it at the gym. Second, the balanced output's improvement in separation as the signal travels on separate ground for each Left and Right channel is marginal at best. Totally not worth the money. Stick with the stock cable and save your money.

Does what it is supposed to do. But WAY over priced for what you get. I will say though, the IEM's are hands down one of my favorites. I own over 50 IEMs and these seem to spend a lot of time in my ears.

Ordered the balanced FiiO cable for my Etymotic ER4XR's after switching to a balanced cable on my HD580's and finding a noticeable improvement. My FiiO M11 DAP doubles it's output in balanced mode and it really drives both the Etys and Sennheiser's to produce better sound. Very happy with the investment

Very nicely done! Cord is too long… makes it more of pain now. It gets caught on everything.

good

The sound quality was noticeable when they worked. Erratic operation and cutting out on occasion. Had to return.
