Massdrop x Hifiman HE4XX review – revealed new king



When you hear someone say “planar magnetic drivers,” it often brings either a lot of questions or the impression that it is just a really expensive headphone for audiophiles. However companies have been striving to bring better sounding headphones for lower budget. Recently, two companies that have been leaders in producing great products at a low cost for costumers have teamed up to bring you the ultimate deal in a planar magnetic headphone. You can read about these two companies down below.


HiFiMAN Electronics is a designer and manufacturer of audio products including headphones, amplifiers, and portable audio players. Hifiman is known for its high-end audio products made under the brand Mee Audio. Its most popular products include the HE-400 which are full sized open back headphones and the RE-400 which is an IEM (In Ear Monitor). Both products are supposedly critically acclaimed for their sound quality



Not only for audiophile gears but for many other things, this website has been doing something called “drops” for the community. They collaborate with companies such as HIFIMAN  to bring the best value for the costumers. The only catch is that you can only jump into the drop once its available for a limited time and that it takes a while for them to prepare and ship it to you.

OVERALL, I found the build quality to be excellent for the price. The only complaint I had was the stock cable that was too rubbery for my taste

The looks and hinge system is similar to that of the old HIFIMAN he400. However, the new headband made all the differences in the world as I could tell that the comfort level was significantly better.


Also the plastic used on the headphones seems descent and solid. It has a matte look to it compared to the shiny finished look on the original he400. BUT do not let the looks deceive you as these headphones are not he400 (skip to sound quality to learn more)


Again, the headphone hinge and adjusting mechanism is similar to the he400

Pads are however the more recent pads that hifiman uses, which are much more comfortable than the original he400 pads in my opinion
