Hifiman Deva is a new for 2020 full size headphone with planar magnetic driver that can be used wired, wired digital via usb or bluetooth. The Deva has a port for Hifiman's included wire so you can use with dacs and music players as a traditional headphone. You can also plug in the high output Bluemini bluetooth dac / powerful headphone amp. The Bluemini is smaller than it appears in photos. You can connect via usb to your phone or computer and use the Deva as a headphone and dac/amp. You can also connect by bluetooth.
The Bluemini has a built in mic so you can take calls. Connect via bluetooth with AAC for iphone, or the high res codecs found in android phones: LDAC, apt-x HD, HWA/LHDC for excellent clarity and dynamic sound quality.
The fit/finish and overall look is a big step up for Hifiman - its a very attractive headphone in person. Comfort is great, with roomy pads, deep headband padding and a not too tight fit - these are open back so they will not get too warm. Really these are incredibly versatile.
