Audio-Technica Truly Wireless In-Ear Headphones ATH-CKR7TWGY

Audio-Technica truly wireless in-ear headphones ATH-CKR7TWGY. Grey. Exceptionally pure audio of Sound Reality in a true wireless design. Mic and controls built into the earpiece for convenient handling of calls, music playback and volume adjustment. 11 mm exclusive drivers (with diamond-like carbon coated diaphragms and pure iron yokes) provide extremely accurate, high-fidelity audio. Brass stabilizers reduce resonance and ensure linear diaphragm movement. High-quality DAC with headphone amplifier (AK4375 from AKM) delivers clear and accurate sound reproduction from the wireless signal. Housing’s dual-layer isolation structure keeps the electric circuitry separate from the acoustic space for optimal phase and transient response. Stainless steel acoustic mesh resistor provides improved high-frequency response. Internal battery provides approximately 6 hours of continuous use on a full charge. Portable power bank charging case gives you an additional 9 hours of use without needing to connect to an AC power source. Included interchangeable 3D Loop Support can be used to provide a more secure fit. Compatible with aptX, AAC and SBC codecs.
