Wireless Headphones/Earphones Specifications

Earcups Type: Semi-open
This design allows for a balance of sound isolation and ambient sound awareness. Semi-open earcups can provide a more natural sound profile and may prevent the feeling of pressure in the ears, which is often associated with fully closed designs.

Bluetooth Version: 5.0
Bluetooth 5.0 offers improved connectivity, greater range, and better power efficiency compared to previous versions. This upgrade allows for a more stable connection with compatible devices and can provide higher audio quality during playback.

Battery Life: Up to 4 hours
This indicates that the earphones can play audio continuously for up to four hours on a single charge, which may be sufficient for short listening sessions. The charging case likely extends usability significantly.

Total Harmonic Distortion (THD): 5
A THD of 5% indicates the level of distortion present in the audio output. While low distortion is desirable for high-fidelity audio, a 5% THD is relatively typical in consumer headphones; sound quality can vary based on other factors like driver quality and design.

Charging Method: Charging case
This confirms that the earphones come with a dedicated charging case that stores and charges the earbuds when not in use, facilitating portability and ease of use.

Maximum Wireless Range: Less than 10 meters
This indicates the maximum distance between the headphones and the paired Bluetooth device. While this range is typical for Bluetooth devices, users should ideally remain within this range for the best audio connection and quality.

With Microphone: Yes
The inclusion of a microphone allows for hands-free calling, voice commands, and possibly voice assistant integration, enhancing usability for communication and control.
