Audio Technica will release the open-air structure wireless headphones "ATH-HL7BT" on November 12th. The price is open, but it is expected to sell for around 20,000 yen including tax. The main feature is that it adopts an open-air structure as a wireless headphone that supports high resolution when used with wires. Since the back part of the headphone is not sealed, it enables a liberating listening style, and it is said that you can feel the natural sound and spread of the sound together with the surrounding air. The development background is that as people spend more time at home these days, there are more opportunities for online communication such as listening to music and movies and telework. Explain that the width may be widening. It is said that the ATH-HL7BT has appeared as a model that allows you to enjoy entertainment and communication at home with better sound and comfort. Equipped with a large diameter φ53mm driver to achieve high-quality sound with a sense of presence in addition to the open-air structure. It is also equipped with a high-quality Hi-Fi DAC and headphone amplifier, realizing wideband reproduction with natural and rich acoustic characteristics, and appealing that it can clearly reproduce powerful low frequencies and beautiful mid-high frequencies. In addition, as a "360 Reality Audio certified headphone", it supports the music experience "360 Reality Audio" that utilizes Sony object-based 360 stereophonic technology. It is possible to optimize the sound field and the acoustic characteristics of headphones from the dedicated app "Connect". The company explains, "By combining audio technology that Audio-Technica has cultivated over many years, you can fully experience the world of sound that the creator envisions." To listen to 360 Reality Audio content, a separate subscription to a compatible music service such as Amazon Music Unlimited is required. We are also particular about the feeling of wearing so that it can be used comfortably for a long time. It has a lightweight design of about 220g, and various ingenuity has been implemented, such as distributing the burden when wearing it by taking a large contact area between the headphones and the person's head, and reducing the feeling of tightness by lightening the lateral pressure. The main body is a dark gray body with anti-fouling paint, creating the image of a “deep music experience”. Equipped with operation buttons that can play music, make calls, adjust volume, etc. In addition, by combining fabric materials that are compatible with the interior, we are aiming to achieve both design and functionality. The ear pads have a two-layer structure. The "fitting layer" that touches the ear uses a soft cushioning material to improve wearability, and the "acoustic layer" that transmits the inner sound uses a harder cushioning material. By creating a constant acoustic space between the ear and the driver, the aim is to achieve optimal performance regardless of the size or shape of the head or ear. Equalizer settings can also be used with the dedicated app "Connect". In addition, it supports a “share function” that allows you to share your customized equalizer with other users. At the moment, only the ATH-HL7BT among the company's wireless headphones supports this function. As mentioned above, the share function allows you to share your own equalizer settings on SNS for other users, and you can also listen to other people's equalizer settings. ”. Original (flat) equalizer and 4 presets are also available. In addition, you can also select the number of volume steps on the app, and you can change the default setting of 16 steps to 32 steps/64 steps. Built-in two small high-performance MEMS microphones. Beamforming microphone technology enables clear conversations by picking up only the voice of the speaker, and the open-air structure allows you to talk while listening to the surrounding sounds, enabling more natural conversations. Bluetooth version 5.0, codec supports SBC/AAC. Supports low-delay mode that suppresses the gap between sound and video. The mode can be turned ON/OFF from the app. In addition, it also supports the multipoint function that allows you to connect to two devices at the same time. Continuous playback time is about 20 hours. It supports fast charging and can be used for about 150 minutes with about 10 minutes of charging. It also comes with a 2.0m cord with a φ3.5mm stereo mini plug, so it can be used wired. It also supports high-resolution sound sources when used wired. The playback frequency range is 5Hz - 40kHz, the impedance is 48Ω, and the output sound pressure level is 100dB/mW.
