1MORE Quad Driver E1010 In-Ear Headphones Silver/Gray

Quad-driver in-ear headphones

The 1MORE Quad Driver E1010 uses four drivers per earpiece, combining a diamond-like-carbon driver with three balanced armatures to cover highs, mids and bass. A 45° oblique nozzle angle matches the ear canal for secure fit and passive isolation. The aluminum sound chambers weigh 18.5 g and include an in-line microphone and remote for calls and playback control. A 1.25 m cable terminates in a 3.5 mm plug for universal compatibility.

Hi-Res frequency extension to 40,000 Hz

The 20-40,000 Hz range reaches beyond standard audio bandwidth, capturing transient detail that creates a sense of realism. Sensitivity of 99 dB and 32 impedance allow adequate volume from smartphones, tablets and laptops without a dedicated amplifier. Buyers who need wireless convenience or active noise cancellation should consider other models, as this design relies on a wired connection and passive isolation only.

3.5 mm wired connection with in-line controls

The single fixed 3.5 mm plug carries both audio and the control-box signals, so devices without a headphone jack cannot use these headphones without a separate adapter not supplied in the box. The four-driver acoustic architecture and aluminum chambers are tuned by Grammy-winning engineer Luca Bignardi for a warm, spacious signature. Nine pairs of ear tips and a travel case are included for fit customization and protection.
