WIRED’s review finds the $1,200 SJY Zeph open-back planar magnetic headphones to be an unusually detailed, lively and well-made option for serious listeners. Their standout feature is a reversible magnetic earpad design that subtly changes the sound profile, while their minimalist handmade construction is expected to aid durability; however, their specialist requirements and weight limit their mainstream appeal.

The reviewer awarded the Zeph 9/10, praising its precision, texture and unexpectedly satisfying bass across reference tracks by the Who and Radiohead. The headphones need at least one watt of power per channel and use a 4.4mm balanced connection, meaning most buyers will need a capable dedicated headphone amplifier; their price was listed at $1,200, reduced to $999.
