Yes, it's all subjective. I have Denon AH-D5000, Fostex Massdrop TH-X00, PSB M4U 2, and Oppo PM-3 headphones. Since I bought my HD800s, I still use my PSB noise cancelling headphones when flying, but I use my Sennheisers for everything else. Every time I listen to my HD800s, I'm amazed by what I...

I don't find the HD800S boring at all. I listen to jazz, folk, classical, and classic rock on them, and I always enjoy how the music sounds like music, rather than bass-heavy noise. I wanted headphones that delivered the music to my ears in the purest manner. The HD800S headphone is perfect for...

The online calculator on this page could be useful for you. https://www.audiobot9000.com/ Enter 600 Ohms as the resistance, efficiency of 96 dB/V for the Beyerdynamics DT-990, and a loudness of 115 dBSPL, which is very loud and you limit your exposure to those sound pressure levels for >1...

Hi. Will the MHA50 bypass the DAC on older Apple products such as an iPod Classic 160 GB. Have you seen the specs or tests on the MHA50? I'd like to compare it with my current amps before I consider buying one. Thanks!

Thanks. 

Thanks, Koukol. My X5ii is malfunctioning, if this is the case:  "As I said you can cue up any song on the player while another is playing or paused (stopped) However the cued song won't play until you click play." Thanks, Heath

Hi Koukol, Thanks for your help. I must not be explaining what I perceive as a problem correctly. I do not want my X5ii to start playing tracks automatically. If I stop a song and then forward to another song, the second song begins playing immediately, even though I paused the first song. I...

Thanks for you help, but I think that my explanation was unclear. I want to be able to push the pause button and forward (or reverse) to another track without the track starting to play automatically. For example, if I'm listening to track 1 on an album and decide that I want to hear track 4...

The song cueing problem still persists and I've upgraded to the newest firmware each time it becomes available. For example, is it possible to go from track 1 to track 3 without having track 3 starting to play automatically? Thanks.

Which Mediabridge cable will work for the Oppo PM-3? I'd like one that will allow a 1/4" screw on plug like the stock cable that came with the PM-3, but I'd like a shorter cable. It seems that the cable is odd-sized where it plugs into the PM-3 ear cup. Thanks.

Hi Koukol, I only learned recently that batteries should discharge infrequently. Best, Heath

If I understand correctly, modern batteries stop charging after they are full of charge, so leaving the Fiio X5II connected to a power source should not affect its battery life.

Thanks, this was very helpful. I need to try the gentle slope version. Heath

Thanks for your help, JackiesFridge. I'm glad that I didn't buy an old X5 case, due to the size difference between the X5 and X5II. Heath

Hi, have you made progress toward increasing the font size for the X5II? It's a great player, but it's difficult to read. Thanks!
