Magaosi K3 HD In-ear Earphone Review

Introduction –

Magaosi’s K3 Pro was an immensely popular model that offered great value with a triple hybrid driver setup housed within a robust metal shell. And in real world testing, I found the K3 Pro to produce convincing ergonomics and an engaging if not supremely natural sound. That being said, they still weren’t quite as flawless to my ear as some early impressions had suggested and the K3 Pro, while an immensely impressive earphone for the price, had some very notable shortcomings.

So just a few months later, Magaosi have followed up their winning hybrid formula with the new K3 HD, ditching their previous triple driver setup in favour of a more integrated single dynamic +single balanced armature design. With the addition of a much-improved cable and accessory suite in addition to a slightly increased price of $120 USD, $10 higher than the original K3 Pro, let’s see whether Magaosi’s refined design brings similar audible and ergonomic benefit.

I would like to thank Chi Kong Hui from Penonaudio very much for getting in contact and providing me with the K3 HD for the purpose of an honest review. All words are my own and despite receiving the earphone free of cost, I will attempt to be as objective as possible in my evaluation.


Accessories –


As my review sample is a pre-production unit, the build quality and packaging do not reflect that of retail units though the accessory suite should be identical.


Upon opening the package, I was relieved to see that the K3 HD comes with a very practical zippered hard case; one of my main gripes with the original K3 Pro was its impractical fabric case that was neither spacious nor portable. The new case is very well sized and has classy leather texture, it is a little thicker than most earphone cases, but comfortably holds an extra cable and accessories in addition to the earphones themselves.


The K3 HD also comes with 2 pairs of silicone tips and 3 pairs of foam tips. Both are identical to those included with the K3 Pro, the silicone tips are a bit flimsy but the foam tips provide solid seal and isolation. Magaosi also includes two cables with the K3 HD, a silver-plated unit with a straight plug and a basic OFC cable with a right angle plug for portable use. Neither have a remote, but it’s good to see Magaosi shipping two cables from factory, the silver plated cable, in particular, is a rare addition even amongst vastly more expensive earphones.

  1. Hi. How do the Kinera H3 compare to the Magaosi K3 HD?

    I can not decide between the two!.

    I have the TFZ Series 5S, (and the Mee 6 pro, Senheisser Momentums in ear, Audio Technica IM50, various other TFZ cheaper earphones). Thanks. Mark.

  2. Hi Shaan,

    Glad you’re enjoying the Simgots, I have the Kinera H3 at the moment, it is proving to be a really interesting earphone. I haven’t had enough time with the Kinera’s to provide an exact comparison here, but I will be sure to give some reference to the Quad Drivers in my full review. The HD isn’t a huge upgrade over the K3 Pro, but it is a nice earphone that justifies that price increase, I still wouldn’t recommend it if you’re looking for a natural earphone with an outstanding soundstage like the EN700 Bass.

  3. Hi Ryan,
    I remember you giving 9 rating to the magaosi’s previous earphone and from your review it seems HD’s are a step above their predecessor. I’m guessing HD’s are rated lower since they are priced slightly higher than k3 pro.
    Anyway, I got my en700 bass couple of weeks ago and enjoying them a lot especially in the mid and high frequencies. Mids and highs are sweet and clear. Bass is not clear though and sometimes a little muffled and cloudy. Soundstage is seriously wide too. I think they are great for the price I paid.
    Now I’m thinking to add 1more quad to my limited budget iem experience. I also read about Kinera H3 and was wondering if you have had any luck trying them?
