Tahsin Sevgel Audio Devices

Hi;
My name is Tahsin Sevgel, and I have worked as a mechanical engineer in the past. After graduating from the Mechanical Engineering department at METU, I began my career by working on thermal power plant projects at a research center. During this period, I realized a long-held dream of mine by developing the Warbler Audio Prelude, a custom in-ear earphone, after an extensive process.

I am pictured at the Afşin Power Plant during my engineering days.

Drawing on the experiences gained in my mechanical engineering career, I decided to venture into producing custom in-ear monitors for musicians under the RevoStage brand. RevoStage products gained significant popularity among musicians and were preferred by many renowned individuals. Engaging in the world of music and sound allowed me to express my creativity and brought immense joy to my life.

Now, I have embarked on a new adventure, returning to my hometown to escape the chaos of Istanbul. I am currently living in Hisar, a natural and tranquil village in Kiraz, the smallest district of Izmir. Here, I believe I will have the opportunity to freely bring my unconventional engineering ideas to life while enjoying a peaceful life. Additionally, I plan to dedicate more time to hobbies I have long been interested in, such as analog photography, and explore the natural beauty surrounding me through plenty of walks.

The word 'Hisar' means 'castle' in Turkish. This refers to an ancient castle in our village dating back to the Roman-Byzantine era, and the village itself is named from this castle.

This new lifestyle will provide opportunities for both personal and professional discoveries and experiences. By maintaining my enthusiasm for future projects and hobbies, I look forward to relishing a calm and nature-immersed existence.
