Sony has announced four new references Bluetooth headsets, available from May. Model entirely conventional in audiophile, through the headphones for sports or product noise reduction, Sony rather broad breaststroke .
Sony today announced four helmets or rather three helmets and a pair of headphones, all with Bluetooth connectivity. The first model, MDR-ZX330BT positioned at 90 €, is the classic 30mm transducers, closed design, frequency response of 20 Hz to 20 kHz (limited by Bluetooth) and speakerphone to take calls. His little more: it has a NFC module facilitates pairing Bluetooth. Failing that, quite big: after the batteries are flat, the headset is no longer usable. Fortunately, Sony evokes still 30 hours of battery life.
For the more energetic users, Sony offers the MDR-AS600BT and splash finish. It is Bluetooth-ear, with silicone lugs supposed enhance retention on the ears in case of increased movement. Small diaphragms 9 mm cover here too the maximum frequency response supported by the Bluetooth wireless connectivity of 20 Hz – 20 kHz. This model will be sold at 80 € with different tips and ear holders.
More upscale (160 €), the MDR-ZX770BN is a circumaural with active noise reduction. Good news here headset continues to operate wired necessary once the 13 hours of autonomy have been achieved (with active noise reduction, Bluetooth and NFC). The frequency response of the Bluetooth (20 Hz – 20 kHz) then extends to 8 Hz – 22 kHz wired. Side sensitivity Sony announces 98 dB / mW with active anti-noise feature (23 ohms) and 100 dB / mW when disabled (50 ohms). These measurements being data cable in both cases.
Finally, the must is undoubtedly the MDR-1ABT. In the image of its high price positioning elsewhere (€ 350) … He joined his older, MDR-1A, but adds Bluetooth connectivity and inaugurated the house codec LDAC announced during CES. A codec that can play high definition files encoded at 96 kHz (max speed of 990 kbps, three times the 352 kbps of aptX). Handsome, except that the only compatible mobile device for now, the Walkman NWZ-A15 … The DSEE treatment allows it to improve the quality of normal flow to get the most “liquid crystal polymer transducers coated aluminum. “Wired, the frequency range of 4 Hz to 100 kHz is quite phenomenal!
