Handcrafted Bubinga Wood Housing

These wired in-ear headphones use real bubinga wood enclosures instead of plastic or rubber, paired with 8mm dynamic drivers and a 32 ohm impedance. The natural wood construction is designed to resonate with the audio signal for a richer tonal character. A 3.5mm plug provides universal wired connectivity to phones, computers and tablets without any pairing or charging required.

Passive Noise Isolation and Zero Power Draw

Sound isolation is achieved physically through the in-ear fit and supplied eartips, so no active circuitry or battery is involved. The tangle-resistant cable carries the signal directly from the source device, meaning there is no latency, no charging routine and no power consumption from the earbuds themselves. An inline microphone with approximately 3K ohm impedance handles voice pickup for calls and voice assistants.

Travel Pouch and Six Eartip Pairs Included

The package supplies a protective carrying pouch plus six sets of eartips so you can find a secure seal for daily commutes or desk sessions. An inline remote on the cable lets you answer calls, adjust volume and control playback without reaching for the device. Because the connection is purely analogue 3.5mm, there are no firmware updates, no wireless drop-outs and no compatibility concerns with older hardware.

Questions about this item

How do I install the 3.5 mm plug and what step do people miss?

Insert the 3.5 mm jack fully into the device port until it clicks; the step often missed is seating it completely so both audio channels and the microphone connect.

What parts will need replacement later on these earbuds?

The silicone ear tips wear out first; the pack includes six pairs so you can swap them when the seal degrades.

What limit appears first during long listening sessions?

Passive noise isolation blocks ambient sound but does not cancel low-frequency drone, so bass-heavy environments leak in before the drivers distort.
