Features and Construction

The T2 Smart Edition is defined by its core audio technology and dual-connection design, offering flexibility for different user preferences.

Material and Build

The headset's construction features a metal stretching rotary folding design. This mechanism enhances portability by allowing the headset to collapse into a more compact form and increases structural firmness during use. The design is presented in a choice of black or white colour options.

Size and Practical Fit

The primary measurable specification is the 1.5-metre length of the included audio cable for wired connectivity. The headset does not support memory cards and lacks active noise-cancellation technology. Its key audio components are built around a large Φ57mm 16Ω drive unit, which works in conjunction with the proprietary turbine cavity technology to produce sound.

Uses and Placement

This headset is suited for various scenarios, from professional environments requiring long battery life to casual home listening where sharing audio is a benefit.

Event or Professional Use

The 40-hour music playback and 45-hour talk time make this headset suitable for long-duration events, travel, or work scenarios where frequent recharging is impractical. The 10-metre Bluetooth range allows for movement within a room or office without losing connection. The app control feature provides professionals with a tool for fine-tuning audio settings to suit different tasks or media types.

Everyday Home Use

For home use, the headset serves as a versatile audio tool. The included 1.5-metre wired cable with a line-out port enables users to share their music directly with others who have wired headphones. The turbine cavity technology and large driver aim to deliver clear audio across a wide 20-20,000 Hz frequency range for music, films, and gaming. The physical volume control offers immediate adjustment without needing a connected device.

Benefits and Buying Value

The value of the T2 Smart Edition lies in its combination of long battery life, control options, and audio technology, presented for users seeking a multifunctional headset.

Reuse and Low Maintenance

The product's primary maintenance relates to its rechargeable battery, which supports extensive use between charges. The metal folding design is intended to withstand repeated opening and closing for travel. Care for the materials should follow general guidelines for electronic devices and metal components to maintain appearance and function.
