In this video I review the Hifiman Deva, Hifiman’s new “entry-level” modern planar at $299 that also doubles as a Bluetooth headphone via a clip-on module. I go over the basic specs, build, comfort, and what you actually get in the box—including the stiff 3.5mm cable, USB-C charging, and the Bluetooth/USB DAC-amp module. Build-wise, I think it’s honestly better than a lot of recent Hifiman stuff: thick padded headband, metal yokes, and (thank you) actual swivel. Comfort is solid for me, but the Bluetooth adapter hanging off the cup looks pretty bad and kind of clashes with the consumer styling they were going for. Sound-wise, I confirm there’s no DSP in the Bluetooth module, so wired and wireless FR is the same. The Deva doesn’t extend bass like I expect from a planar (roll-off around ~60Hz), dynamics feel a bit compressed, and the midrange is the big issue: it’s thin, uneven, and just “off,” which matches the jaggedness I see in measurements. Treble is mostly fine, but detail for $300 isn’t amazing and timbre comes off plasticky—more like a 400i/4XX vibe than a Sundara. My main takeaway: if you’re buying it purely wired, I’d spend the extra $50 on the Sundara. The Deva only really makes sense if you specifically want an open-back planar that can go truly wireless at this price.
