Audio Technica ATH-R70x vs Sennheiser HD 650 – Detailed Specs Comparison (2026)

Breathable fabric earpads and improved wing support provide long-wearing comfort. Carbon composite resin improves structural rigidity to provide detailed transient response. Feather-light weight and robust construction make headphones perfectly suited for professional use. Acoustically transparent, aluminum honeycomb-mesh housings provide a natural and spacious open-back sound. Unique, dual-sided detachable locking cable is L/R signal independent, always ensuring proper stereo orientation. High-efficiency magnets and pure alloy magnetic circuit design reduce distortion and ensure accurate and extended high-frequency response. 3 YEAR WARRANTY: With over 50 years of Japanese Innovation and Quality behind it, this comes with a 3-year warranty from Audio-Technica that covers manufacturing defects.

- Systems with narrow tolerances (Â± 1 dB), hand-picked in pairs - Highly optimised magnet systems for minimum harmonic and intermodulation distortion - High-quality titanium/silver finish - A specially developed damping element, made from fine acoustic metal mesh, ensures a precise damping over the entire diaphragm surface, highly constant in all climates. - Extremely lightweight aluminium voice coils ensure excellent transient response - Specially modulated connecting cable (detachable) made from highly conductive OFC copper, with very low handling noise, i.e. low structure-borne sound sensitivity - Gold plated 1/4" jack plug with adaptor lead to 3.5 mm jack plug - 2-year warranty
