I find the triple flange sleeves with the white filter gives the best seal and sound quality than olive stock and foam tips.

But when I used it in a milder weather, I still felt a little bit of hot in the jean's pocket.

I wonder if the stack of Mojo and 120II will create overheat if placing in your jacket or pocket. As I noticed when I play DSF or 24/96 while during shoving the snow for an hour,I felt my pocket has a warmer there.

Thanks for the explanation. That make sense.

I can understand the importance of cue sheet in cycling's GPS navigation. but what is the function of this cue sheet in a portable player?

  Do you meant that SE535's Mids (Vocals) are coloured to be more thin (and less lush) than SE846 ?

Agreed with you. Whenever your AK gets really warm or even hot after and during charging, its not good. I would rather keep 0.5 amp slow charge even though it takes about 8 hours to fully charge.

As long as your source DAP and or DAC is at least worth as much as SE846. Then you can fully utilize the performance of SE846.

AK120ii with 2.5mm balanced output will lower the impedance to 1 ohm which is perfect match with SE846. I only used balanced output with SE846 except line out to blue tooth speaker,

I concur with you. I like the clarity and high fidelity details of the balance out of AK120II and no harshness, even with 320 MP3. I emphasize on vocals of Pop. It gives me enough warmth and lushness. For 3.5mm single out from AK120II, there's no comparison with 2.5 balance out.

Thanks for your tryout. It seems that you misunderstood my second question, I want to know that the volume adjustment in your M9 can increase/decrease to a very small degree to get a desirable listening level.

Do you hear any hiss and can you mini adjust the volume to your desirable listening level on your M9 ?

I read somewhere that we should recharge the battery from fully discharged once a month to fully charge to prolong the life of the battery.That's why I wait to charge until the battery is fully discharged.

It took me 8.5 hours to fully charge my AK 120II which has 0% battery left from my Bluetooth speaker in slow charge. Is it normal ?

Good that you have no issue with yours. Mine will pause even though the Gapless playback is on.
