Whizzer HE01 Review


For the nitpickers and nerdy ones here, I’m giving the specs and technical sheets. For all the others, you can just go to the next page to see how the Whizzer HE01 performs.

Dynamic Driver + HDSS

Like the ddHiFi Janus we recently reviewed, the HE01 only gets a single dynamic driver. No hybrid design, no multi-BA configuration, just a sole – proprietary – driver. That said, the brand introduces some cool features that make the HE01 worthy of your attention.

First and foremost, the Whizzer gets a super-wide, 4th generation, 10.2mm driver. That’s much bigger than your usual 8mm driver and even a little more than the one you’ll found in director competitors’ models. Advertised as a 4th generation model, this transducer gets a composite diaphragm and a 1.2 Tesla magnet to push the sound to the max.

The driver itself is then merged with a copper ring, the HDSS, which allegedly “improves the sense of sound density and transparency, creating a cleaner and mellow listening atmosphere”. I’m pretty curious to hear if that makes a difference.

Comfort and daily use


The H01 are good noise blockers, but there’s room for improvements.

If they are more than adequate for places like my office or a crowded room (even if not everyone respected social distancing), they didn’t stop the sound coming from the train while I did my weekly commute.

In that regard, I may suggest you add Comply Foam tips if you want to use them in really noisy spaces like a train, a subway, or a train. 


If the Whizzer HE01 doesn’t get a semi-custom shape, they still feel supremely comfy. In fact, the first time I plugged them in my ear, I was speechless to see how well they fitted in my ear. If the brand only offers two sets of silicon pairs (regular and vocal) the first try did the trick.

Even after a few hours of listening, I couldn’t fault those ears, which stood tightly inside my ears. The same goes for the cable: light and sturdy. A good combo, on-par with more expensive models in this regard.

Let”s check the specs and continue into the review.

A nerdy guy with a passion for audio and gadgets, he likes to combine his DAC and his swiss knife. Even after more than 10 years of experience, Nanotechnos still collects all gear he gets, even his first MPMAN MP3 player. He likes spreadsheets, technical specs and all this amazing(ly boring) numbers. But most of all, he loves music: electro, classical, dubstep, Debussy : the daily playlist.
