Universal wired earbuds

The Koss KE10B connects to any device with a 3.5 mm jack for a reliable wired signal. Stereo drivers cover a frequency range of 40 Hz to 20 kHz, delivering deep bass and clear treble. The in-ear design keeps audio focused on the listener without disturbing others nearby. Soft foam cushions expand to create a secure seal that blocks ambient noise.

Foam comfort and isolation

Memory-foam tips mould to the ear canal for a custom fit that stays comfortable during long sessions. The seal improves passive isolation so external sounds are reduced without active electronics. Cables run straight from the buds, keeping the profile slim enough to wear with glasses, earrings or any hairstyle. No battery or pairing is required, so the earbuds work instantly on every compatible device.

Simple upgrade from stock buds

These replace basic bundled earphones that lack proper isolation or low-frequency response. The wider frequency range reveals detail in bass lines and vocals that cheaper drivers miss. Foam tips solve the fit issues that cause hard plastic buds to fall out or leak sound. The jump is worth it for anyone who wants better clarity and comfort without moving to wireless or premium-priced models.

Questions about this item

What does the 3.5 mm jack connect to?

The 3.5 mm plug works with smartphones and other devices that have a matching headphone socket for a wired stereo signal.

How do the foam cushions fit in the ear?

The soft foam expands inside the ear canal for a custom fit that seals out ambient noise and sits clear of glasses, earrings or hairstyles.

How are the earbuds set up for the first time?

Insert the plug fully into the 3.5 mm jack, then press each foam tip into your ear until it expands and seals; the step people miss is waiting for the foam to fully expand before listening.
