Advantages of the model
Planar magnetic transducers have a thin, flat diaphragm with embedded leads, suspended in magnetic space. This design allows the diaphragm to move like a piston across the entire frequency spectrum. This diaphragm is lightweight and has good transient response, making planar transducers a better choice for sound reproduction than dynamic transducers.
Innovation
In these planar magnetic headphones with EqualMass, different wires with the same width have been connected in parallel, thus achieving a uniform driving force for all parts of the diaphragm while keeping its weight evenly distributed. This configuration allows the diaphragm to move back and forth with the same speed and impulse, reducing harmonic distortion to almost zero. In the second generation of EqualMass wiring, the brand has created a symmetrical wiring structure, further improving diaphragm stability across the entire frequency spectrum.
Thus, the Edifier EqualMass diaphragm achieves an even distribution of mass and a uniform force across its entire surface. As a result, the headphones reproduce the original sound with ultra-low distortion and fast transient response for superior audio performance.
Sound Fidelity
To ensure uniformity in the distribution of magnetic field intensity in each planar magnetic transducer, a set of automated tools has been launched to calibrate and compensate the magnetic circuit. This allows each set of S5 headphones to deliver sound fidelity similar to the designer’s crafted gold sample.
Compatibility
In addition to LDAC and LHDC, the S5 also supports all Snapdragon Sound Technology Suite audio codecs, including aptX HD, aptX Adaptive, and aptX Lossless. It achieves high-resolution audio (24-bit/96kHz) and bit rates of up to 1.2Mbps in Bluetooth mode for low end-to-end latency. It also supports the AAC codec, which improves compatibility with a variety of devices.

In short, with the LDAC and LHDC codecs, they support both Hi-Res Audio via USB and AUX connections, and wireless Hi-Res Audio via Bluetooth.
Power and consumption
Built with Qualcomm’s latest QCC5181 Bluetooth SoC platform and Qualcomm Snapdragon Sound technology, they deliver a strong RF connection and low power consumption.
The Qualcomm aptX Adaptive codec preserves all original bit-perfect content with high resolution (up to 24 bit/96 kHz sample rate) and low end-to-end latency.
Special Features
Supports simultaneous connection to two Bluetooth audio devices. Whether it’s a mobile phone or a laptop, switching between devices is convenient and fluid, allowing you to work and listen to music simultaneously.
They incorporate dual microphones and Qualcomm CVC technology to dynamically reduce ambient noise and improve voice for optimal voice quality.
Thanks to compatibility with the Edifier Connect app, you can use the headphones and their remarkable functions: custom equalizer adjustment, control adjustment, ear cushion adjustment, etc.
This model offers up to 80 hours of music playback. Also, a short 10-minute charge provides 11 hours of playback.
The newly designed adjustable headband presents a comfortable and cozy wearing experience. The pads are made of genuine sheepskin and cooling mesh pad.
The foldable structure and carrying case allows you to take them anywhere.
