Product Description
The wired earphones Tech-Protect Ultraboost Core G4 are in-ear headphones with a 3.5 mm plug, designed for devices equipped with a standard audio jack. Made from durable materials ABS and TPE, they impress not only with their sturdiness but also with their light weight and comfort of wear. The 3.5 mm connector ensures a stable connection and a clear signal without interference.
Sound Quality

The frequency response of 20–20,000 Hz guarantees a full musical experience — strong, deep bass and crystal-clear highs make your favorite tracks sound exactly as they should. The digital transmission of 16bit / 44.1kHz captures every detail of the recording with high resolution without compression. The ergonomic design of the earbuds ensures a good fit in the ear, allowing you to listen to music for long periods without discomfort.
Ease of Use

The 120 cm long cable made of flexible TPE provides freedom of movement in everyday situations — at work, while traveling, or during workouts. The built-in remote control on the cable allows you to change tracks, pause and resume music, adjust the volume, and answer or reject calls — all without reaching for your phone.
