    Your links are for the Mk1 not Mk2......?????? Where can a poor boy get the Mk 2? Why did the USA get the best prices on the MK2? C'mon give us Europeans a fair price like you did in the US. Grrrrrr.

    1. If you care to read the post fully it clearly state that you will receive the mk2.

    2. Prices in the US are always communicated without taxes, I'm also pretty sure that EU had better customer protection (warranty).

    Thinking of getting one of these to use with my PM3. not long after i sold my PSB M4U8, i started wishing i had a BT headphone that sounded at least as good as that, and i tried the Beyerdynamic Lagoon. They sound fantastic when connected to my jotunheim and gumbi, but don't quite cut it for BT use. So decided to entertain the idea of the ES100, but i have a few questions. These are to help me visualize this a bit mor, as i'm completely blind. from what i can tell about what's published for dimentions it is light for sure, but in getting one of these BT dac-amps, i'd like to ideally have a super small cable from the ES100 to the PM3 and possibly mount the ES100 maybe to the cup of the PM3? maybe that isn't really feasible or the ES100 is to bulky for that, but goal is to turn my PM3 into a wireless headphone as much as possible. Also, what's the difference between the 1st and 2nd versions of the ES100?

    qUOTE="kukkurovaca, post: 15358783, member: 473630"]No, the Qualcomm chipset that the ES100 uses for USB.

    The Qudelix 5K will go higher, but not as high as the BTR5 which uses XMOS for USB. This was discussed recently in the Qudelix thread:



    I didn't fully read the 2nd link that was quoted. The es100 has 2 dacs and according to the link the qudelix, through btr5, only uses one of it's 2 DAC but again at higher bitrates. Is this also true for es100? Btr5 only using 1 DAC as opposed to 2 when used with a cable? If this is true would this mean that even tho I'm using 2.5mm I'm not getting that balanced output since it's only using 1 DAC?

    Good news. Will we receive any firmware update in the future for this device, or now you are focusing on new devices only?
  9. subwoof3r
    2.0.2 is the last firmware released in janurary 2019, as specs are the exact same between MK1 and MK2 I don't think there will be any new firmware for a very long time.

    There still can be improvements especially on the software side.

    What are the main differences between mk1 and mk2?

    Radsone posted a detailed list of the exact differences. If you search the thread above, you’ll find their post.

    Hi guys,
    if it can help, I made few photos to help comparate MK1 vs MK2 :

    Thanks for the photos, friend! To be honest though, I don't think the changes in the Mk2 are radical enough to make me think it's much better than the Mk1. As someone who just bought two of the Mk1 in the past couple weeks, it doesn't look like I'd be gaining much by buying the Mk2. Sound wise, everything is the same with both. And I'm totally loving the sound of all my iems with the Mk1. @Slater said it best a while back...best money I ever spent on a piece of gear. This thing is so versatile, has so many options, and can provide so much control of the sound...it's silly not to have one.

    I do exactly this to a Q701, and a K371.



    It would look more compact if I could find and redo this with right angle or 45 degree connectors, but this works. These only get used at home. On the go I just use Galaxy Buds.
