Bluetooth headset with stereo wired connection featuring Blue String T2 Smart Edition 4.1 technology, 1.5m cable length, 10 metre transmission range, 40 hour music playback, and choice of black or white colour
Blue String T2 Smart Edition Bluetooth Headset with 40 Hour Playback and Wired Connection

The Blue String T2 Smart Edition 4.1 headset provides flexible audio connectivity options combining Bluetooth wireless technology with traditional wired stereo connection. This dual-functionality design offers users the convenience of wireless listening within a 10 metre range while maintaining the option for direct wired connection when needed. With substantial battery performance delivering up to 40 hours of continuous music playback and 45 hours of talk time, this headset supports extended usage periods without requiring frequent charging. The inclusion of a 1.5m cable ensures compatibility with audio sources lacking Bluetooth capability, while volume control functionality allows immediate adjustment of audio levels during use. The headset's construction incorporates practical design elements aimed at improving user experience through enhanced portability and reliable performance across different listening scenarios.
Features and Construction

The Blue String T2 headset integrates several technical specifications and design features that contribute to its audio performance and practical usability. From its audio driver technology to its physical construction elements, each component serves a specific functional purpose supported by measurable specifications.
Material and Build
Construction incorporates metal components in the stretching rotary folding mechanism, providing structural reinforcement while enabling compact storage. This design approach enhances the headset's durability during transport while maintaining firmness in its extended position during use. The housing materials come in black or white colour options, with plastic elements forming the main body structure. The 1.5m cable features standard audio connection components with integrated volume control functionality, allowing direct adjustment without requiring device access.
Size and Practical Fit
The headset's physical dimensions include a 1.5m cable length for wired connection, providing sufficient reach for most stationary listening setups. The metal stretching rotary folding mechanism enables significant size reduction when collapsed for storage or transport. The Φ57mm driver unit represents a larger-than-average audio transducer size, which contributes to the headset's audio reproduction capabilities. While exact headband and earcup dimensions aren't specified, the folding design suggests accommodation for varied head sizes through its adjustable mechanism.
Uses and Placement

This headset serves multiple listening scenarios through its combination of wireless and wired connectivity options. The substantial battery life and technical specifications make it suitable for different usage environments, from personal entertainment to communication applications.
Event or Professional Use
The 40 hour music playback capability supports extended event coverage or professional monitoring applications where continuous operation is valuable. Bluetooth 4.1 technology with 10 metre range enables freedom of movement in controlled environments without connection interruption. The line-out connection type provides compatibility with professional audio equipment when wired connectivity is preferred for signal integrity. The 16Ω resistance ensures broad compatibility with various audio sources commonly used in professional settings.
Everyday Home Use
For domestic listening, the headset offers substantial battery life reducing charging frequency for daily music enjoyment. The folding design facilitates convenient storage in limited home spaces when not in use. Volume control on the wired connection allows immediate adjustment without accessing connected devices, useful for quick response to changing audio preferences. The 20-20,000 Hz frequency response covers the full audible spectrum for general music, video, and gaming content consumption.
Benefits and Buying Value

The headset provides practical advantages through its combination of technical specifications, dual connectivity options, and design features that address common user requirements in personal audio devices.
Reuse and Low Maintenance
The headset's construction with metal reinforcement in key mechanical areas contributes to repeated use durability, particularly in the folding mechanism subjected to regular manipulation. The substantial battery capacity reduces charging cycles, potentially extending overall battery lifespan through fewer complete charge-discharge cycles. The absence of memory card support simplifies maintenance by eliminating file management considerations associated with onboard storage. Standard connection types ensure compatibility with future audio sources through widely adopted interfaces.
Why Choose This Product
This headset offers distinct advantages for users requiring extended wireless operation alongside wired connection capability. The 40 hour music playback substantially exceeds typical Bluetooth headset battery performance, reducing charging interruption during extended use periods. The Φ57mm driver unit with turbine cavity technology provides enhanced bass response potentially preferred by listeners valuing low-frequency reproduction. The folding mechanism with metal components offers practical portability without compromising structural integrity during regular transport. Dual connectivity options ensure usability across different audio sources regardless of their wireless capability.
