Наушники — 64 Audio Volür

The Volür from 64 Audio of the USA is a hybrid earphone in universal fit that puts ten drivers in each earpiece. Two dynamic drivers handle the low range in an isobaric pair, while eight balanced armatures take over everything above. It sells at USD 2,499 and ships with the gold m12 Apex module fitted.

Key specs that matter

The driver split per side is two low dynamic units, six balanced armatures for the mids, one balanced armature for the upper mids and one tia high balanced armature, divided by an integrated four-way passive crossover. 64 Audio rates frequency response at 5 Hz to 22 kHz, sensitivity at 103 dB per mW at 1 kHz with 94 mV, and impedance at 6.3 ohm at 1 kHz. The in-ear housing is a closed design whose isolation depends on the chosen Apex module.

Engineering and use context

For the bass section the company created a new 9 mm dynamic driver with an upgraded N54 magnet and a cone that combines a 25 micron polyurethane layer rated for 115 degrees Celsius with a 19 micron titanium layer, aimed at raising sensitivity. Two of these drivers sit cone to magnet in what 64 Audio calls a True Isobaric arrangement, linked by an acoustically inert coupling chamber. The maker lists better damping, lower distortion, doubled power handling and wider low-frequency response as the results of this layout. At the top, the direct-radiating tia driver works with a new tia waveguide that has integrated diffusion windows, which the company says improves efficiency in the treble band. The internal structure of the shell was redesigned to leave maximum room for the low-frequency bore. Apex modules vent air pressure from the ear canal and come in four versions - mX, m12, m15 and m20 - giving -20, -15, -12 and -10 dB of isolation, so a stage user can pick more sealing and a home listener can pick more venting.

Pairing

The box includes a black 3.5 mm cable, a leather carrying case, foam and silicone ear tips in several sizes and a cleaning tool. With impedance this low, a player or headphone amplifier with a very low output impedance keeps the load on the source close to what the maker specifies, and the high sensitivity means small portable players can drive the Volür to high levels. Users planning to switch to a balanced source need a replacement cable, since only the 3.5 mm lead is supplied.

Alternatives

The 64 Audio U18s is a universal in-ear model built around eighteen balanced armature drivers per side in a CNC-milled aluminium shell.
