LUDOS OMNITONE 3.5mm Wired Earphones

The LUDOS OMNITONE are wired in-ear headphones with a 3.5mm jack and an inline microphone. They weigh 40 grams and are intended for listeners who want a direct analogue connection without battery charging. The package includes a protective case and the cable.

3.5mm Analogue Connection Limits

The 3.5mm plug relies on the host device for digital-to-analogue conversion and amplification. Sound quality and maximum volume therefore depend on the source hardware rather than the earphones themselves. No wireless pairing or battery management is required, but the cable restricts movement to its 4.2ft length.

32 Ohm Impedance and Daily Use

A 32 ohm impedance makes the OMNITONE easy to drive from phones, laptops and tablets for music, calls and video conferences. The single-ear coupling and sound isolation suit focused listening in quiet to moderately noisy environments. Buyers needing active noise cancellation or multi-driver detail for critical monitoring will find the specification insufficient.

Questions about this item

The OMNITONE only comes in black with a 3.5 mm plug — are there other colours or connectors?

This model is supplied in black only and uses a fixed 3.5 mm jack; no alternative colours or connector types are listed.

How does the 32 ohm impedance affect volume when I plug the OMNITONE into a phone or laptop?

At 32 ohms the earphones draw enough power from a standard headphone socket to reach loud listening levels without an extra amplifier.

What does the 3.5 mm connection actually limit compared with a digital or wireless link?

The analogue 3.5 mm jack caps audio quality to the source device's built-in DAC and prevents any wireless or digital-audio features.
