The Technics EAH-A800 headphones mark the Japanese brand’s entry into the over-ear noise-cancelling headphone segment. Launched in 2022, this model offers 50 hours of battery life with active noise cancellation, high-quality call performance thanks to its 8 microphones, and a sound signature true to Technics’ audiophile approach. It is aimed at users seeking a balance between technical performance and everyday usability.
Acoustic Engineering and Drivers
At the heart of the EAH-A800 are 40mm dynamic drivers featuring an innovative three-layer diaphragm combining PEEK and polyurethane. This hybrid design provides both the rigidity needed for precise detail reproduction and the flexibility required for deep bass. Technics engineers have paired these speakers with specially designed acoustic control chambers to optimize airflow inside the earcups.
This architecture allows the headphones to deliver an extended frequency response from 4Hz to 40kHz, earning them Hi-Res Audio certification. The soundstage particularly benefits from this technical approach, offering precise imaging that reveals subtle details in recordings. Multilayer thin-film capacitors, borrowed from the brand’s high-end amplifiers, stabilize current in the audio circuit to limit distortion.
Noise Cancellation System and Audio Processing
The EAH-A800’s noise cancellation system combines a dual hybrid approach with both analog and digital processing. Four external microphones capture ambient noise (feedforward) while four internal microphones analyze residual sounds (feedback). This configuration achieves attenuation of around 25 dB in the low and mid frequencies.
The headphones offer two transparency modes: Transparent mode, which lets in all surrounding sounds naturally, and Attention mode, which focuses on voices while filtering out background noise. This flexibility is especially useful on public transport or in work environments.
Connectivity and High-Resolution Audio Codecs
The EAH-A800’s Bluetooth 5.2 connectivity supports SBC, AAC, and LDAC codecs, the latter enabling high-resolution audio transmission up to 96kHz/24-bit. This compatibility with Sony’s codec ensures optimal quality with compatible Android devices. The multipoint function allows simultaneous connection to two devices, making it easy to switch between a smartphone and a laptop.
Battery life is a major asset of this model: 50 hours with noise cancellation enabled using the AAC codec, and 40 hours with LDAC. These figures far surpass the competition, with fast charging times of 15 minutes for an additional 10 hours of listening. A full charge takes about 3 hours via the integrated USB-C port.
Design and Everyday Ergonomics
The EAH-A800’s metallic silver finish features a sleek, professional look, with reflective metal discs on the earcups evoking the world of Technics turntables. The primarily high-quality plastic construction is reinforced with metal elements at stress points. The hinges allow for compact folding for transport in the included hard case.
The over-ear memory foam cushions, covered in synthetic leather, distribute pressure evenly for prolonged comfort. A metal spring in the headband reduces pressure on the top of the head. The weight of 298 grams is reasonable for the category, though some users may experience fatigue during very long sessions. Compatibility with glasses is excellent thanks to the adaptive cushions.
Control Interface and App
The hybrid control interface combines physical buttons and a touch surface on the right earcup. Dedicated buttons manage volume, play/pause, and power, while the touch surface mainly activates noise cancellation modes. This approach avoids the accidental triggers common with fully touch-based controls.
The Technics Audio Connect app offers fine control of the 5-band equalizer, with presets and the ability to create custom profiles. Noise cancellation settings are adjustable from 0 to 100%, allowing you to tailor isolation to your preferences. Wear sensors automatically detect when the headphones are removed to pause playback, with automatic resume when put back on.
Call Quality and Microphones
Call quality is a distinctive strength of the EAH-A800. The eight built-in MEMS microphones use beamforming technology to isolate your voice while suppressing background noise. The wind noise reduction system significantly improves clarity during outdoor calls.
This setup outperforms most competitors, including Sony and Bose models, for professional communications. Amazon Alexa integration allows direct voice activation, though the feature remains limited compared to native smartphone assistants. Managing simultaneous calls on two connected devices is seamless.
