I had used Massdrop Zeus IEM during 10 hour flight from Seattle to Incheon, Korea on Aug 4th.
What a joy!
With using IEM supplied by Delta Airline, the music or sound from movie sounds mundane.
But with MD Zeus IEM, I had been happy with dynamic, nuanced treble and realistic soundstage throughout 10 hours.
It made my trip much easier.
I had crossed Pacific Ocean more than 100 times but this is the best occasion to enjoy sound out of Airline source.

Be careful not to have it burn out. It happens. |
Are you insane? I just got through burning it in for 240 + hours.

While you are waiting, maybe it is a good idea to buy another CD player. Things break when used and your model is getting a bit old and used up.
I am talking about your CD player model.

No need, I am really glad and am not fishing for praise. |
Oh, didn’t I thank you? 😳 |
"...I’m continuing to run the XLO track on repeat." I am glad to be of help. |
Finally! After more than 240 hours of burn in, including more than 5 straight days (how time flies!) using the burn in track of the XLO Test CD, the thin, tinny, distorted and bass shy sound disappeared. Well, almost all of it. There still isn’t much bass so I’m continuing to run the XLO track on repeat. Will make a final judgement in about 4 days. That should put me over 300 hours. |
Quick update on progress with burn in of HIFIMAN RE-600S V2 earphones. I finally switched over from using Zeppelin and Kraftwerk and Beastie Boys for burning them in after about hour 140. I now have about 16 hours logged on the System Burn-in Track 9 on the XLO Test CD. Hopefully this will cut my time to pure audio nirvana. George is getting fidgety. 😬

There appears to be many inexpensive options to drive headphone well.
But Dave and Mscaler that I had got for my 2 channel system 4 weeks ago, also seems to be excellent for driving earphones and headphone. |
Gang, for a portable amp/DAC, try the Fiio BTR3. Bluetooth connectivity only. With the right headphones it is amazing, especially for a tiny, $70 device: https://amzn.to/2LrltRF |
I agree that my HIFIMAN RE-600S V2 sounds very fast - like electrostatic headphones. But, trust me on this, even with 130 hours on them they’re a long, long way from high end sound. But I’m patient, unlike some people. 😀 I will give them the full 300 hours before making any judgements or pronouncements. It’s a long way to Tipperary.

HIFIMAN RE800 Silver is not neutral but sounds like electrostatic one.
Thus if you are interested in such fast and transparent sound, you may give it a try.
|
after 130 hours I can say definitely the HIFIMAN earphones still sound very unnatural, distorted, with an unsmooth frequency response, no bass. But they sound good on Kraftwerk because it’s all synthetic, even the voice. So, as far as I’m concerned you didn’t wait nearly long enough to judge them fairly. You are not in a position to judge them. You have to wait at least 300 hours. 😢
|
After 100 hours of burn in, its treble edges are gone.
But even with this burn in, its balance is not neutral despire clean and detailed treble.
Thus I am in a position to evaluate Hifiman RE800s. |
As I’ve oft repeated the high end earphones from HIFIMAN require about 300 💯💯💯 hours of burn in. You didn’t wait long enough if you stopped after 💯 . As I pointed out in the review of the RE-600S V2 earphones from HIFIMAN there was virtually NO CHANGE to the extremely blah sound after 200 hours. I can verify the sound of my RE-600S V2 earphones is a long way from hi end sound after about 130 hours of burn in. I realize you wished to get your evaluation published right away but it appears to be more of a rush to judgement.
