Betron B25 In-Ear Wired Headphones Black 3.5mm 1.2m

Wired In-Ear Headphones for Everyday Listening

The Betron B25 are lightweight in-ear headphones weighing 16 grams with a 1.2 metre tangle-free cord. They use a 3.5 mm gold-plated connector for direct plug-in to compatible laptops, tablets, computers, audio players and game controllers. The aluminium housing and braided cable are built for daily transport. Three silicone ear tip sizes (S/M/L) and a carrying case are included for a secure, portable fit.

Noise-Isolating Fit Without Microphone or Controls

Passive noise isolation blocks ambient sound so music stays clear at lower, safer volumes. The acoustic port controls airflow to optimise diaphragm movement for accurate bass reproduction. No inline microphone or remote is present, keeping the connection simple for devices that only need stereo audio output. A Y-shape cord routes cleanly to each earpiece.

Sustained Listening with Consistent Output

The 9 mm dynamic drivers deliver a 20 Hz to 20000 Hz frequency response with 112 dB sensitivity and 16 ohm impedance. This specification supports steady volume levels during long sessions without requiring external power. Total harmonic distortion is rated for in-ear use, and the signal-to-noise ratio of 112 dB keeps background hiss low across the full frequency range.
