Thanks a bunch for that information. I did look online but all I saw in the brief search was Bluetooth. Think I’d prefer the radio frequency. I’ll look into Lekato IEM.
Please do PM the email address.

I had an email exchange with the person who developed the 2E1 Pro Ears. As I understand the situation George originally made them for himself following a loss of hearing on one side then started making them for others with the same issues.
I mentioned that I had started a post in the Roon Forum concerning his headphones and there was a good bit of positive discussion. He expressed interest and requested a link so he could see it.
The following information was included in an email response after reading the post.
*Mike, I was not expecting that and reading your posts brought tears to my own eyes, what a great early Christmas present for me and Eric Clapton is one of my favorites! Making the 2E1 for our single sided deaf community has also been a healing experience for me which allowed me to heal over the trauma of my acoustic nerve tumor and hearing loss. *
*PS: Please convey to the Roon forum that I just don’t add the Porta Pro drivers from Koss (or Panasonic for the lower end 2E1) into the ear cups - I actually use a proprietary method of mine that I developed that enhances the sound over factory settings. Also anyone trying the same design without my innovations will not get the same results - there will be feed back problems for having two drivers that close, their will be an echo chamber effect like putting a sea shell to your ear, etc. So a lot of mod work goes into drivers that I repurpose for my 2E1. *
Also, the vibrations you are feeling is my other innovation where I mount the drivers in acoustic foam so they free float (this is why I call my innovation “The Flying Echelon” because the drivers free float and are staggered) - while all headphone drivers are glued down and rigidly set inside ear-cups, mine flex and wiggle with the audio creating a sympatric vibration that enhances the overall listening experience.

Thought I’d add an update on using the 2E1’s with the Lekato MS-1 - 2.4GHz wireless adapter.
@jb76 John ordered the adapter for his 2E1 Pro Ears Ultra. Initially he had a slight, intermittent static caused by the signal interference.
Here is an update from John via PM.
After a week John advised he’s not experienced any more interference moving around the house with the wireless headphone setup.
Now it’s my turn. I love these headphones but I am frustrated being attached by cable. Thanks John for leading the way.

I did get the Lekota MS-1 - 2.4GHz wireless setup and it does work very well with the wired headphones.
The first night I tried them out with the transmitter sitting on a low table in the living room next to the media cabinet, middle of the house, while I walked through the foyer, dinning room, kitchen, utility room then out to the garage. The first hint of sound disruption occurred in the garage 4 walls away from the transmitter.
With the transmitter higher up, above the living room pass through to the foyer, and connected to the player with a 15 foot extension cable I expect the usable distance to be greater. I can use them throughout the house with no interference or dropouts. This is really nice.
I did a short A B test, wired and wireless, with a couple of tracks and did not notice any difference in the sound quality. I’ll try that again with some higher res tracks as time permits.
I’m getting my wife regular Stereo headphones for her Birthday and got a second receiver with the original order so we can both listen to our headphones at the same time. That will be great for us watching cable TV and listening to music. We normally require the volume up high while watching TV so the old ear(s) can hear the dialog. With the headphones I can hear every whisper at very low volume so we won’t miss anything.
While looking on the Lekota web site I found they had a newer model, MS-2, that is a little larger with greater range (100 feet), a bigger battery, plus battery and volume level indicators. With the bigger battery the MS-2’s are said to be good for 6 - 8 hours without recharging. The MS-1 is good for 4 to 5 hours without recharging.
For anyone interested in trying wireless with their wired headphone the
Lekota 2.4GHz set works and has more range than Bluetooth.
The cost is minimal. $45 for the MS-1 plus $23 for the additional receiver, and I paid $48 for the MS-2 with the online seasonal discount.
Edit: FYI, My experience may differ from others but does seems to match up with Johns. In my older neighborhood our closest neighbor is 75 to 100 yards away through trees and heavy vegetation so no community interference. I had our house wired with Ethernet for music distribution after purchasing the Roon lifetime subscription in 2019 and the only wireless used in our home is cell phones and Ipads. Phones and IPADs use the 5G band so the 2.4 band is mostly free for the wireless adapter to use.
