True Wireless Zero

“True Wireless Zero” that has one of the latest chipset, and is sparkling in cobalt blue.

“True Wireless Zero”is the first True wireless stereo headphone of ZERO AUDIO. “0” shape LED with “Zero” motif sparkles in cobalt blue to produce special apperence. It is equipped with one of the latest chipset QCC3026 of Qualcomm® and supports Qualcomm TrueWireless ™ Stereo Plus. That makes stability of connection improved dramatically more than preceding chipsets. Both communication speed and communication range are greatly improved, making it easier to connect to devices and realizing more comfortable data transmission. Low power consumption enables long playback time. Supporting Qualcomm® aptX ™ audio, the compression ratio at transmission is lower than other codecs such as SBC, which enables playing music without great loss of sound quality.

Qualcomm® QCC3026 inside
▶TrueWireless™ Stereo Plus

The latest method designed to deliver independent stream to each earbud. Stability will be improved dramatically by connecting with smartphones etc. which support TrueWireless ™ Stereo Plus. a power consumption is significantly reduced.

▶Bluetooth® 5.0

a speed and an area of the communication are improved remarkably, and it realizes comfortable data transmission with less communication failure.

▶Qualcomm® aptX™ audio

Lower data compression ratio of aptX compared to other codecs such as SBC enables better music play with less loss of its sound quality.

Ergonomics design

TWZ-1000 has a structural design in pursuit of a better fit and stability with 4 sizes of Silicone cover. It brings a pleasant fit with comfortable ear-wings.

Decorating by cobalt blue LED

“0”shaped LED in the motif of True Wireless Zero captures its exclusive makeup with shimmering cobalt blue.

LDS antenna

LDS, an advanced manufacturing technology enables antenna layout in ideal position, and exerts stable communication reducing sound breaks.

Compact charging case

With a merit of ultra-low power chip set Charging case is designed compactly suitable for portability.

Graphene coated diaphragm

Diaphragm coated with graphene that is harder material than Diamond produces clear and sharp treble range following ZERO AUDIO sound design.

Built-in MIC

Built-in microphone enables hands-free communication leaving your smartphone in your carrying goods such as bags. Binaural call supported.  ※Receiving call only (Microphone is for Right side).

Wireless communication improved dramatically with QCC3026 chipset

Normal transmission method of tws: communication through the base unit to the other unit; has much risk of sound break because a human head may be a radio wave interference.
The latest transmission method reduces sound break due to each unit individually connects with Bluetooth devices, and achieves comfortableness.*

* Connected Bluetooth device needs to have TrueWireless™ Stereo Plus function being enabled.
