Technics EAH-F70NE HD Wireless Noise Canceling Headphone

40 mm 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 maximize the effects of these characteristics, the shape of the diaphragm was designed with utmost attention to detail.
The special bullet-shaped dome has realized improved rigidity. The natural and linear high-frequency characteristics provide a smooth and lustrous sound. The rib edge shape was optimized 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-res-equivalent*1 Sound Quality Even in Wireless

The headphones support LDAC™, Qualcomm® and apt-X™ HD, and offer excellent response and high resolution even in a wireless configuration to reproduce accurate and faithful high-res-equivalent*1 sound.

*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

The hybrid noise cancelling system combines two different systems to realize 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 Sensor 

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 

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.

High-grade Materials

The outer parts are made of aluminum. The alumite treatment and spin finish bring out the high-grade ambience of the material. The Technics logo mark is laser-engraved and colored. 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.
