Magaosi K3 HD In-ear Earphone Review


Design –

The K3 HD employs a similar design to the Pro before it, producing almost identical ergonomic properties. That same metal construction makes a return, however, Magaosi now offer the earphones in blue and orange in addition to the standard silver/grey.


From a glance, the K3 HD is almost identical to the K3 Pro with the same base housing design. In fact, the nozzle and internal face are identical, producing essentially the same fit. The outer housing, however, has been slightly revised; the HD trades the accented ridging of the K3 Pro for a more uniform, smoothed off design. As a result, they are a slightly larger earphone than the Pro, but they remain pleasingly low profile when worn, effectively minimising wind noise. The HD is also appreciably smaller than the TFZ King and Simgot En700 Bass, they still don’t disappear like the Oriveti Basic and Klipsch X10, but they do comfortably lend themselves to wear when sleeping.


Build quality is unsurprisingly similar to the Pro, they employ the same kind of finish and metal in their housings with a similar nozzle design. One reader contacted me about a nozzle issue on the original K3 Pro, however, the nozzle on the K3 HD felt rock solid, even after a few tugs and twists. They are a vented earphone, producing above average but not outstanding noise isolation. That being said, buyers looking for an earphone to use during travel or in louder areas should probably still consider more isolating earphones like the King, Basic and SE215. Otherwise, the K3 HD is a stable fitting and relatively lightweight earphone that stay put during general commute and a quick run. Their over-ear fit contributes to their stability though the strangle angling of the ear guides on the included cables saps that last bit of solidity from their fitment.


At the top is a conventional MMCX removable cable interface which means the K3 HD will be compatible with a huge variety of aftermarket cables. The included units are hugely improved over those that came with the K3 Pro. The black right angle cable is braided, supple and smooth, resisting tangles very well, perfect for portable use. And while the silver cable isn’t quite as flawless, being a bit rubbery and springy, it is adequate for home use for which it was intended. Both cables have nicely relieved jacks and pre-moulded ear guides as opposed to memory wire. Unfortunately, the ear guides sit at a very strange angle like the cables on the SIMGOT EN700 Bass, making the HD’s fit a bit more awkward than the Pro.

    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 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?

    • 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.
