Truth, Beauty, and Greatness – A Review of the Cayin N5ii


Because the Cayin N5ii is more neutral than warm, with strong treble energy, it pairs well with most headphone profiles, but it does especially well with those of a warmer, bassier disposition.

Andy is fond of extolling the synergy of the Meze 99 Classics ($309, Review HERE) and Cayin’s players. I wholly agree. Something magical happens every time I hook these cans up to the i5, and I get a lot of that same alchemy in the N5ii>99C brew. The tonality sends shivers down my spine, never more so than with acoustic rock. It’s rich, with such mighty, rumbling bass. Vocal clarity is at a crystalline degree. Imaging and depth are addictive. Meze does a wonderful job of showcasing a player’s soundstage, revealing just how good the N5ii is. These are the headphones I use to conduct my critical A/B comparisons between DAPs, and they find a true lover in Cayin.

The Sennheiser + Massdrop HD6XX ($200) is, as we all know, a fairly warm set of monitors, with above neutral bass. The ideal sig for this player. Now, the HD6XX is not meant for portable devices, but even so, on High Gain, they get good and loud to my ears and sound very clean and dynamic. If you run balanced (which I’m not) you’ll have even more headroom.

iBasso has blown me away with their $99 IT01 single-dynamic-driver IEM. Of course, with Tesla magnets and Graphene diaphragms, these are no ordinary DDs. The IT01 is actually a kindred spirit to the N5ii. Neutral-warm, high levels of clarity and detail, energetic and smooth. Naturally, they pair well together. The bass is strong and deep, the treble has good sparkle, and the mids are vibrant. It’s a fantastic setup that won’t break your bank.

This holiday season, whenever I had to brave the tumult of retail, I took the Cayin N5ii and my only set of CIEMs, the Empire Ears Spartan IV ($749, Review HERE). They combine to create a pinnacle of musicality and transparency. A perfect balance is met, where naturalness and emotion swirl together in smooth liquidity. This system never feels like it’s trying. In fact, the “system” disappears, and all you have is music… music that just sounds right.

Finally, how about I bring out the big guns? The 64Audio tia Fourté ($3,599, Review HERE) is the most revealing, transparent, and resolving earphone I’ve yet heard. It opens up the N5ii and brings it to its very limits. With Fourté, I can hear its strengths and its weaknesses. And let me tell you, there are no obvious weaknesses. I can listen to this setup and become so caught up in the perfection of it all I forget I have bigger and better DAPs on-hand. Oh yes, Fourté illustrates the virtues of those other players, but it also shows me the N5ii is a rock-hard f**king gladiator that never fails to wow.

So what more do you need? Buy one today. If your budget is anything under $600, even $599, buy the N5ii. It is jammed full of awesome, and sounds as good, or better, than anything else in this price-range. It is currently my favorite DAP in terms of size and form, and one of the finest-looking things yet wrought by man. The Cayin N5ii is indeed the new King of Mid-Tier. They should be proud of what they’ve accomplished.

About Author

Pinky is an artsy twat. Illustration, graphic design, writing. Yet music escapes him, and always has. He builds his own cables, and likes to explore the craftsmanship of others. He's a stabby one, also. At the first hint of annoyance, out comes the blade. I say he's compensating for something... in a big bad way. If we all try really hard as a collective, maybe we can have him put down.

    Hiby R6 review coming up soon? I would like to know how it compares to Cayin N5ii.

    • Pinky Powers on

      I have no contacts with Hiby, so I’m not sure if or when I’ll get my hands on the R6.

  2. Elric on

    I have it and use it with Noble Sage and Eros II, This is music i want to hear, great sound, great review.

  3. Scott Thouvenin on

    Hi pinky, great review and I’m going to pick one of these up and compare it with my current zx300. I just want to know what the iems were on the second page first picture? They look of gold or brass coloured and look tiny, which I like.

    Thanks again, a real concise review, with humour and wit 😉

  4. Csaba on

    Enjoyable writing – as always. Can’t resist – ordered one right now. Really curious with the Meze 99 Classic (I’ll show my balanced cable project soon (without 3D printed part) ).
    Nice color match Fourté – Symbio 🙂

    • Pinky Powers on

      Oh, that sounds marvelous. You need a webpage with a proper store, Csaba. Keep me posted, though. I’m a fan.

      Good job on the N5II buy. You’ll love it.
