Product Characteristics
Base Model
This collaboration model is based on the TE-Q3, the latest entry in AVIOT’s Q Series, which has shipped approximately 320,000 units*1. Despite being one of the most compact active noise canceling earbuds on the market*2, the TE-Q3 offers up to 11.5 hours of playback on a single charge and up to 42 hours with the charging case. The ear tips are made from skin-friendly, medical-grade silicone*3. In addition to its robust core features, the TE-Q3 is equipped with 10 mm dynamic drivers for high-quality audio, making it a well-balanced model that excels in design, usability, and sound.

There are seven modes in total—six solo modes where each character whispers directly in your ear, and one duo mode featuring conversations between Teuta and the male characters.
