Our Sidekick Events

The Headphone Museum

In addition to the best of today, our headphone museum is ready for a tour – here you will find milestones in the history of headphones and even some gems, including an Urjecklin from 1972, an AKG K1000 from 1989 and much more. And as a special treat, the Sennheiser Orpheus is ready and waiting to be heard!

Another highlight of music history awaits you in the “Pleasuredome”: an original Wurlitzer jukebox from 1947, restored and equipped with modern music. An absolute highlight of music history!

Kii Audio – Experience incredible sound!

We are actually 100% specialized in headphones & co., but with Kii Audio we have been unfaithful to our line for once, but with full conviction. The fantastic speakers from Kii are available to try out in the Headphoneshop. The Kii team itself will be presenting the Kii THREE / Kii THREE BXT models and, for the first time, the brand new Kii Seven.

The Dark Side of Wine … and beer!

Of course, in addition to the countless musical delicacies, there will also be the finest supporting program: Pure pleasure not only for the ears – but also for the eyes and stomach! Among other things, you can look forward to a musical wine and craft beer tasting with the participation of one of the world’s leading sommeliers and a master brewer. 

Vintage watches

Zeitgeist is not only the motto of our unique IEM brand, but also fits in with another item on the program: lovers of exclusive watches can look forward to an exclusive exhibition of vintage watches, which rounds off the varied program. Perhaps Germany’s finest address for vintage watches & modern classics provides an overview of the finest watches and their history.

After-work get-together

We end the day together with a beer, wine or a great meal. Get into conversation with other aficionados, distributors and reviewers or simply enjoy the great atmosphere. Culinary delights will be served at the barbecue, which will include delicious rib-eye steaks in a whisky marinade and a variety of delicacies such as selected types of bread, antipasti and much more.


Due to limited space, free registration is required for the wine tasting, the Kii demonstration and a guided tour of the museum by Thomas Halbgewachs. You can find the registration links below!

Heidelberg is always worth a visit

The city of Heidelberg, known for its picturesque old town, is not only the ideal venue for the “World of Headphones”, but also worth a visit. The old town is within walking distance, and a unique headphone museum awaits visitors in the Headphonecompany store.

During your stay in Heidelberg, it is worth exploring some of the city’s fascinating sights. These include Heidelberg Castle, one of Germany’s most famous ruins, and the Old Bridge over the Neckar. The Philosopher’s Paths offer a breathtaking view of the city and the Karzer, a former student prison, provides an insight into historical student life.

Art lovers should pay a visit to the Kunsthalle Heidelberg, which presents contemporary art exhibitions. The botanical garden of Heidelberg University is a peaceful place for nature lovers, and the Jesuit Church impresses with its baroque architecture.

The “World of Headphones” thus not only offers unique audio experiences, but also the opportunity to discover the cultural and historical treasures of Heidelberg.

Admission is free!

Date: March 2, 2024
Opening hours: 10:00 to 19:00
