Technics is unveiling two new wireless headphones, the EAH-F70N and EAH-F50B. Both models support LDAC/apt-X HD for wireless, high-res-equivalent*1 sound reproduction. Backed by high rigidity and high internal damping, the use of a 40-mm dynamic drivers, consisting of Composite Performance Film(CPF) diaphragm and Precise Air Control Structure enables the new models to faithfully reproduce the delicate nuances of music and dynamic sound. The EAH-F70N features Technics' original wide-band hybrid active noise-cancelling to allow immersion in music under virtually any environment. Both the EAH-F70N and EAH-F50B bring a new style of outdoor Technics sound enjoyment to today's market.
A wireless music experience generating real-life sensations of energy and spatial expansion.
40mm dynamic driver with newly developed diaphragm
This diaphragm is consisted with newly developed composite performance film(CPF) laminated with a plurality of special materials and it has achieved high rigidity and high internal damping . The result is a powerful bass that seems to soar from the bottom depths and a spatial ambience that makes you feel as if you were in a concert hall. To maximise the effects of these characteristics, the shape of the diaphragm was designed with utmost attention to detail.
The special bullet-shaped dome has realised improved rigidity. The natural and linear high-frequency characteristics provide a smooth and lustrous sound. The rib edge shape was optimised through simulation to attain high linearity across the entire input range, from weak to large input. All delicate nuances of music and realistic dynamics are faithfully reproduced.
A precise Air Control Structure
Detailed simulation and fine tuning were repeated to achieve an Air Control Precision structure that results in an optimal air flow. The two carefully designed ports and original construction create an accurate air flow to bring out the wide-range frequency reproduction capability from the driver.
High-Resolution Audio Quality with Bluetooth® and LDAC technology
*Effective with High-Resolution content transmitted with LDAC codec at a max. transfer rate of 990kbps
Fast response and high definition achieved wirelessly; reproducing elaborate, High-Resolution Audio
Quality sounds faithfully
*1: When connected via Bluetooth®, LDAC supports up to 96 kHz/24 bits and apt-X HD supports up to 48 kHz/24 bits (high-res reproduction when connected by cable).
Noise Reduction in a Wide Range of Scenes
Hybrid Active Noise Cancelling - 3 Modes (EAH-F70N only)
The hybrid noise cancelling system combines two different systems to realise high noise reducing performance. A three-level mode selector allows selection of the noise cancelling effect according to the usage situation.
The hybrid noise cancelling system uses two different systems: the feedforward system which uses a mic mounted on the outside and the feedback system which uses a mic located near the driver positioned close to the ear. In addition, the circuit was originally designed to provide improved noise cancelling performance.
Smart & Seamless Operation
Wearing Playback Sensor (EAH-F70N only)
When the headphones are removed from your head, music stops. When they are put back on your head, music resumes. Comfortable, seamless operation.
Ambient Sound Enhancer (EAH-F70N only)
This function lets you listen to background sounds, such as announcements made on a train or in an airport by simply touching the outside of the housing, without removing the headphones from your head.
Voice Assist Activation
Generally, the analogue output signal (Balanced/Unbalanced) and headphone output signal are generated by This function activates voice assistance, such as Siri in the iPhone. By speaking, you can make a phone call, select a music title to play* in linkage with a music streaming service or check the weather or route guidance.
* When using a music streaming service, it may be necessary to link the voice assistance to the account or subscribe to the flat-rate service.
Stylish Design & Comfortable Fit
3D Ball Joint Mechanism
The ball joint mechanism allows three-dimensional movement of the ear cuff to fit the ear at a comfortable angle. The ear pad is made of soft, low-resilient polyurethane foam.
The outer parts are made of aluminium. The alumite treatment and spin finish bring out the high-grade ambience of the material. The Technics logo mark is laser-engraved and coloured. Every detail reflects the high-grade design.
Swivel & Fold Mechanism
The swivel & fold mechanism makes it easy to carry and store the headphones.
3D Ear Pads
The shape of the ear pads is ergonomically designed and low-resilient polyurethane foam is used inside the pads to ensure a snug fit around the ears. The ear pads offer increased isolation and sound insulating performance as well as extra comfort.
