FAQs
Please read our FAQs page to find out more.
What makes the TESNA sound signature unique?
We believe that deep sound clarity is the foundation of true luxury. Tesna products are engineered with a custom-designed Silk Composite Diaphragm speaker unit operating across a high-fidelity 20Hz–20KHz frequency response range. Unlike rigid, mass-market plastic drivers, the silk composite material responds with incredible agility to audio signals. This delivers crystalline highs, warm, velvety mids, and a rich, resonant bass that lets you feel every note and control every beat, bringing a familiar melody right to your fingertips.
How does the Active Noise Cancellation (ANC) adapt to my environment?
To give you absolute authority over your personal space, the headphones are powered by our advanced TESNA T1 Max Dual-Feedback Noise Reduction Chip. This high-performance processor utilizes hybrid dual-feedback technology to constantly sample outside audio, offering an adjustable noise reduction depth of up to 40dB. Whether you are silencing the roar of a jet engine during travel or drowning out ambient office chatter to focus on building a legacy, you can effortlessly dial in the exact level of isolation you need to maintain your acoustic sanctuary.
Can these headphones manage high-end business calls and virtual meetings?
The Tesna Pods Ultra represent the absolute cutting edge of wireless engineering by incorporating Bluetooth Version 6.0. This protocol provides a completely seamless, zero-friction connection with an ultra-stable, 10-meter barrier-free open environment working distance. It drastically minimizes latency, optimizes battery consumption, and ensures your connection remains entirely uninterrupted by crowded wireless environments.
What materials are used to ensure long-term comfort and style?
True luxury balances meticulous aesthetic appeal with high-performance utility gear. The structural chassis of the over-ear headphones is crafted from premium, high-grade ABS + PC (Acrylonitrile Butadiene Styrene + Polycarbonate) composites. This specialized blend delivers a lightweight, incredibly durable, and scratch-resistant frame. Coupled with plush, ergonomic ear cushioning, the headphones distribute pressure evenly, making them feel weightless even during marathon listening sessions.
Are the Tesna devices protected against moisture and workouts?
Yes. An active, high-performance lifestyle demands gear that can adapt to any environment. The headphones are engineered to an IPX4 Daily Waterproof protection level. This ensures that sudden outdoor weather changes, unexpected splashes, or intense, high-energy workouts will never compromise the sophisticated internal architecture of your device.
Do Tesna devices pair with the Tesna™ app?
Yes. The Tesna app unlocks EQ controls, firmware updates, and the TESNA Music Library.
Are Tesna devices compatible with all smartphones?
Yes. Tesna earphones, headphones and speakers connect seamlessly to iOS, Android, and Windows devices via Bluetooth.
