NOBRAND KZ ZAR Earbuds Restored Tech Other 670530906778

The NOBRAND KZ ZAR in-ear monitors are listed as Restored Tech in the color Other, UPC 670530906778. Their hybrid 1DD+7BA configuration combines one dynamic driver for bass with seven balanced armature drivers for mid and high frequencies. The dynamic driver uses a proprietary low-frequency magnetic circuit with a gap of about 0.15mm and a four-layer voice coil wire for deep, elastic bass.

Three 50024S dual-unit balanced armatures form a mid-to-high frequency array for vocal clarity and presence. A 30019S balanced armature replaces the 30095 to extend ultra-high frequency performance and improve resolution. The frequency response is 20 to 40000Hz, and the U-shaped tuning emphasizes bass and the mid-to-high range for instrument separation and a lively, natural sound.

Impedance is 16.5±3Ω and sensitivity is 109±3dB, allowing use with common smartphones, players, and DJ gear. The detachable 0.75mm 2-pin cable is typically made from oxygen-free copper or silver-plated oxygen-free copper to reduce signal loss. It can be replaced or upgraded, including with a cable that has an inline microphone or higher-conductivity materials.

A standard 3.5mm plug provides wired connectivity. Ergonomically shaped resin shells with metal accents and multiple sizes of silicone ear tips provide a secure fit and passive isolation from sounds such as traffic and crowds. The monitors can be used for music listening, DJ monitoring, gaming with directional cues, and sports.

They support KZ accessories including the AZ09 PRO Bluetooth cable and are accessory-compatible with the ZAX, ZAS, and ZSX models.
