JVC HA-SZ2000 Headphone, Overview

Gone are the days when audiophiles turned their noses up at anything that didn’t remotely resemble a flat response headphone. When even the slightest bit of bass boost elicited delirious rounds of laughter from the so called ‘purists’.

Nowadays the world has changed; people are beginning to appreciate the merits of an extra thump in bass. There is a greater appreciation for why we need to deviate from monitor type headphones once in a while, to let loose and dive head first into the pure unadulterated fun that comes with head-pounding bass.

I feel it’s with that sentiment in mind that the JVC HA-SZ2000 headphones were made.

  • Strong build quality
  • Thunderous bass
  • Great isolation

  • Small comfort issues
  • Highs overshadow mids a bit
  • Amp required for full potential


From afar the SZ2000’s don’t seem very different from the traditional over-ear monitor headphones you’ve probably seen lying around somewhere in your wannabe DJ/producer cousin’s home studio.

Large and even slightly oversize, the black cans have a distinctly military look about them. That’s not to say they’re ugly, on the contrary, the look suits them very well, giving them a rugged handsomeness that doesn’t come by very often in the audio equipment market.

The headband is thickly padded with soft material and covered by comfortable leather. The same material extends to the earcups. While the material itself is comfortable, the overall comfort of the earcups is kind of ruined by their shallowness.

They’re so shallow that while the outer material does indeed sit on your skulls, the inside inadvertently presses against your ears. As a result, these pristine looking headphones are only comfortable for a couple of hours. How many exactly will depend on your level of tolerance, to be honest, max was 3 hours for me.

Because these are closed over-ear headphones, you’ll automatically expect to have a good isolation, however, I have to say that noise isolation is just about average. It’s still sufficient enough for use at the office where it’s relatively quiet, but using these when riding the subway will probably force you to turn up the volume a bit.

Thanks to the good seal of the earpads you don’t have to worry about them leaking too much sound out, meaning you can pump up the bass while keeping peace with other members of your household.

A 1.2-meter cable extends from one of the earcups to a gold-plated 3.5mm jack.

While most of the material is made from hard plastic with aluminum trimming, you get the sense that these headphones are quite sturdy and should be able to withstand some heavy use.

Featuring two drivers, a 55mm low-end frequency dedicated one and a 30mm driver for the mids and the highs, there’s simply no chance of getting bad quality sound from these headphones.

That said the sound signature, as mentioned in the beginning, is pure bass. It’s an effortless reproduction of low-end synths that should get the blood pumping for anyone never mind bassheads.

This doesn’t mean the other frequencies are neglected, the mids are distinct and highs were without a doubt colored.

That perhaps is the one criticism when it comes to the sound because the highs tend to overshadow the mids a little. It’s only noticeable when you’re really trying to pick it out though so it shouldn’t worry the average listener.

At high volumes, the bass doesn’t get muddied and that’s largely thanks to the brass vibration inhibiting cylinders in each ear cup.

Incidentally this, together with the two drivers, is the reason why these are bigger than other similar headphones.

I do recommend the use of a dedicated headphone amp, as, without it, the bass can be somewhat underwhelming. This is because of the two drivers which naturally requires a bit more juice. You can check out some great suggestions here.

For the bass lover, these are almost perfect, except for the fact that they aren’t as comfortable as they could be, especially if you’re going to be wearing them for more than 2 to 3 hours at a time.

However, if you’re going to be using these for short periods at a time, on your commute, to watch a movie, to block out some noise from your colleagues while you get down to business for that one hour you actually work, then these are perfect.

Indeed, if you can switch the earpads out for a more comfortable pair then you have a great set of headphones that’ll set your teeth rattling every single time you put them on.

Add that they are really durable to the mix and you have a winner on your hands.

With its dedicated 55mm bass driver, the JVC HA-SZ2000 has the potential to rumble off your head when combined with a headphone amp.

  1. I have been browsing through many headphones the past couple off weeks while I was looking for some good bass headphones. Your review may have given me a option to look into further, I trust JVC as a brand so I can see them being of a good high quality standard.

    Thank you, All the best


  2. Thanks for this thorough review of these JVC headphones. I’ve been using some great noise cancelling headphones, but sometimes it’s nice to have a pair that let a little outside noise in. For instance when I’m walking alone outside – it’s good to hear the sounds of traffic. While they may not be the most comfortable headphones, they sound like they could get me to work and back just fine. Thanks again!
