Thomas Halbgewachs, founder of Zeitgeist Germany, told StereoNET:

"We're breathing new musical life into trees that have come to a natural end. These trees have seen hundreds, even thousands of years of history: our artisans treat them with the reverence they deserve and ensure their beauty lives on. No pair of Trees earphones is identical – each has its own organic patterns of growth and grain – which just adds to their wonder,"

The collection includes four models, each using wood sourced from a different region of the world.

The California Sequoia is made with wood from the giant redwood trees that dot the coasts of California and Oregon. This wood imparts a warm, red hue and straight grain pattern to the shell.

The African Zebrano uses zebrano wood, which is native to Central Africa. With dark brown and black streaks resembling a zebra's stripes, the wood's wavy grain is said to be hard to saw and plane, meaning extra care and hard work has to be put into making each shell.

Crafted with wood sourced from olive trees in the Mediterranean, the Mediterranean Olive earbuds have a beautiful golden hue and wavy grain.

Last but not least, the Yucatan Redheart features wood from the Redheart tree, which is native to Central and South America and has a deep red hue.
All the earphones are handcrafted in Zeitgeist's workshop near Heidelberg, Germany, and no two earphones will ever be identical due to the different textures, grains and colour variations in the wood used.

The company claims to have studied thousands of ear impressions to find the perfect fit for most people, and thus, the earphones are offered in both Regular and Small sizes. While there isn't much info on the drivers inside, Zeitgeist describes them as a proprietary tuned, 2-way balanced armature system from Sonion with a 17ohms impedance and a frequency range of 15Hz to 35kHz.

Each earphone comes with a 5-year warranty after registration, and a 1.2-meter silver-plated copper cable with either 3.5mm or 4.4mm termination can be selected at the point of purchase. Five Final Type E ear tips, from XS to XL, are also included, and everything comes packaged in a nice display case.

The California Sequoia and African Zebrano retail at €999, while the Mediterranean Olive and Yucatan Redheart are priced at €899. The Zeitgeist Germany Trees Collection is now available for purchase via the brand's website or at luxury stockists like Harrods and Selfridges.
