    I wanted to cut one down short enough to attach the ES100 to the HD650 kind of like I did with my Q701.

    Thanks for the comment! I'm definitely on the lookout for another ES100 now. I like how the app gives so much control and extra features to this device. Hoping to snag one again within the next week or two. Hopefully, the new unit will not be defective. I'm going with this because of all the great reviews here on headfi and how unique and practical it is; all with the added bonus of high sound quality and an excellent portable solution. I really think you hit the nail on the head my friend, when you said that I already have alot of great gear. I really enjoy all of the iems I currently own and don't really need many more. I WOULD like a better source...but I'm sooo in love with how great my Q1MK2 sounds, it's really hard to justify spending 3-5 times as much on a dedicated DAP. SQ-wise, I'm luvin it! I really dig how great it is to use my Samsung S8+ with its snappy fast Android system and the fact that it has an SD CARD slot up to 256g. I currently have a 32gig card in it (90% full with WMA LOSSLESS files in 1411 mbps, and FLAC files...both types ripped from music I already own on CD). Got a 100 gig card that I haven't even opened/used yet. THAT is the main reason I want a device like this. I want to use the capability of my phone as a music player/server, without sacrificing all of the phone's other abilities, just to obtain excellent SQ.

    So you are the perfect ES100 user, just without an ES100 for now :slight_smile:
    Too bad you initially received what I presume to be a defective unit. The jacks themselves are the one sturdy metal thing on this all-plastic enclosure, so odds are next time will work better.

    To me, it is perfect for what it does. No complaints.

    I'm definitely hoping so. I guess one thing I've known since I had to send my defective one back is...I'd definitely be trying another. I never deleted the App. Lol!

    Made me laugh. Mine certainly did, or at least tried to. The little metal loop on the clip that a peg goes through to hold it on broke on one side. I currently have the clip held on with a small ziptie around the whole unit because I like having the clip.

    If you take the clip off, there is basiccally no putting it back on, right?

    No there isnt

    Mine came off at one point (hinge pin fell out), but I was able to put it back together, and it’s been ok since then. After I put the hinge pin back in, I put a dot of cyanoacrylate on the end of it, and it has stayed put.

    Can someone explain the DAC "digital filters" a little bit in depth? What are they all about?

    They deal with reducing frequencies above hearing thresholds. Sharp is usually a standard since it represents the audio signal the most accurately. Slow can sometimes suppress 1-2db in the upper treble, and though I can't personally hear the difference, I'm not sure why it's ever used. I leave mine on Sharp.

    I've been using the short delay sharp roll off setting.

    I presume that cable is DIY? I'm hoping to get my Sennheiser HD598s connected to ES100, but initial (few hours) googling did not turn out too well. I'm still looking for quality 3.5 - 3.5 cable that'd be short enough (10 - 20 cm), and 2.5 -> 3.5 mm adapter that'd would fit Sennheisers (twist lock removed). Or short 2.5 - 3.5 cable, but haven't found that either. Amazon is full of 4$ crap, and I'd like something little classier (AND I live in Europe, which doesn't seem to help).

    I think best option would actually be balanced 2.5 - 2.5 mm cable, but TRRS "order" in sennheiser and ES100 seems to differ, and there's even conflicting information about Sennheisers TRRS, so this seems impossible..

    Yea, the cable I'm using is just a chopped up and reterminated stock Q701 cable.
