Barrett Creative Lamina V2 Stand - Drop Exclusive
Review Highlights:
expand_less
For such a low price this headphone deserves 5 stars for sheer bargain prowess! So long as this is plugged into a decent amplifier the sound opens up and is terrific! By contrast, anyone expecting to plug this into their cell phone or laptop computer is missing the point, without decent amplification this headphone will not sound as great as it can(more likely dull, actually!). I am driving this through an IBasso Bushmaster D14, which in turn is amped via an RSA Mustang P51 on high gain. I find this combination with the HE4XX heavenly, also because the P51 almost completely eliminates the Sabre DAC's glare. So my recommendation is to buy the HE-4XX, but only if you drive this through a decent DAC/AMP combo!

Planar Magnetics Like You’ve Never Seen Before

Many headphone companies have tried their hand at planar magnetic drivers, but none have done it quite like HIFIMAN. The result of founder Dr. Fang’s PhD research at Columbia University, its driver technology has landed the company in TIME, Forbes, and CNET’s “The Audiophiliac,” and won it the CES Editors’ Choice Award. Now, that tech is available at an unheard-of price in the Drop + HIFIMAN HE4XX: a pair of high-efficiency, open-back planar magnetics that don’t need a fancy amp to sound amazing. Listen to them directly from your smartphone, laptop, or desktop computer, or add a headphone amp to take them to the next level. The sound is smooth, engaging, and even across the frequency range, with airy, sparkly highs and the planar bass slam that HIFIMAN is known for.

Premium Aesthetic, Comfortable Feel

Comfort is king for the HE4XX, which features HIFIMAN’s Focus-A hybrid ear pads: the best-feeling, best-sounding pads the company has to offer. The foam has extra cushioning and is specially angled for acoustics, and the part of the pad touching the ear is made of soft, luxurious velour. A revival of the original HIFIMAN style with some structural improvements, the headband is made of spring steel—so it can bend without losing its shape—and hand-stitched with breathable protein leather. Done in an exclusive midnight-blue colorway, the matte finish is soft to the touch and resistant to fingerprints. The attention to detail is evident throughout, down to the robust steel gimbals with a black oxide finish and matching Allen screws.

HIFIMAN: For Audiophiles, By Audiophiles

Born in New York City in 2007, HIFIMAN has had a big influence on the audiophile world in the 10 years since its founding. Dr. Fang has always had close ties with the community. He started out on Head-Fi and attended local meetups while pursuing his doctorate at Columbia. When he realized his PhD research could be relevant to his passion—the music-listening experience and the audiophile products that improve it—he started talking with forum members and meetup attendees about what they’d like to see in the next generation of headphones. HIFIMAN is a natural partner for Massdrop because our goals are so aligned. At its core, it represents a member of the audiophile community building a company that serves the rest of the community.
