Let me get things rolling:
I have bought this almost the week they came out. You might wonder why I did not talk about them despite owning them for a while. Well truth is I use them for commuting purpose and I never truly sat down with them to do a proper listen. Maybe particular it might have to do with my false initial impression I had regarding the cable which was completely false. I thought perhaps the cable will not be durable as it feels way too 'cheap', what was that saying, 'Dont judge a cable by its cover?'
If I was to rank my IEM based on how they scale when they are paired with various amp/dac the Qjays will score a perfect 10/10. They scale up rather significantly. Going from something like xDuoo X3 which I use with qjays as my daily communing match which I am well aware of its sound and going to the chord hugo and qjays pairing the improvement is very noticeable. You might ask what are those improvement, the easy answer is across all things sound related; increase in soundstage both depth and width, firmer bass, improvement in midrange detail and better treble extension.
To me the QJAYS are a natural upgrade for those who enjoy the ER4P. What QJAYS does is improve across all aspect of ER4 series without having any peaks in the upper frequency range. Texering, and instrument placement for a dual balance armature is considerably better than the IM04. In terms of coherency this is as good as a single driver design. I might perhaps like to have a bit more airy sound, it might not be as airy as the F111 but the rest of the sound it leaves the F111 in dust.
Isolation is well with the right tips. I had problem with all the stock tip and the comply tips I bought from QJAYS. I thankfully saw the post made by ClieOS which suggest Shure olive and yes he was right. At least for me the improvement in terms of comfort, isolation and bass quantity is noticeable.
Now the down side is that you wouldnt get the best of the qjays from your ipod touch, not fro your current sony DAPS, you really need a beefy amp and it will make this thing sing. I paired it with monolith sound potion and it result were favourable. Paired with chord mojo and you are in heaven. Chord HUGO gives a better soundstage but mojo provides a warmer sound which happens to work really well with QJAYS.
Summary: What I hope for qjays to release an aftermarket 2.5mm TRRS cable. I love to pair this with Venturecraft Valoq. Would I recommend this at their retail price, hell yes! And no I did not get a free sample I bought this and put it for test for well over a month. Lets just put it this way currently right now I turned off my Shure KSE1500 to listen to qjays paired with Chord Mojo. If you are seeking for a IEM that is has a neutral sound with a great respond in scaling to perform better than its stock setting look no further. I consider this better than the current Audio technica flagship IM04, a clear maturity over the Etymotic ER4 lineout. Perhaps the ER4S might come across as having more treble resolution but I sense that is to do with the tuning than actual treble extension.
I will try to add more later on source pairing and I am happy to answer any question members might have.
