The "Bluemini" Bluetooth receiver is included in the scope of delivery of every Deva headphone. Plugging it into the balanced 3.5mm socket of the headphones, you can simply receive Bluetooth in the codecs LDAC, aptX-HD, aptX, AAC and SBC. The USB-C connector serves as USB-DAC as well as for charging. The batteries in the approx. 25 gram heavy Bluemini should last 7 to 10 hours in Bluetooth mode and 4 to 5 hours in USB DAC mode without simultaneous charging.
Without the Bluemini module, the Deva is a completely passive and analogue planar magnetic headphone with an impedance of 18 ohms and a weight of about 360 grams. USB C and headphone cables are included in the scope of delivery, as is the adapter from 6.3 to 3.5 millimetre connection. The HiFiMan Deva with Bluemini costs around 350 Euros.
