UNDERSTAND THE DETAILS
K39, in detail.
Look more closely at the construction, finish choices and the battery configuration of the K39.
An attached earpiece and a clothing clip.
The retractable cable connects the earpiece to the main body, so both remain together when carried. The clip places the unit on clothing while the earpiece extends toward the ear. This arrangement separates the body controls from the part worn in the ear.
- Return the earpiece toward the body between listening sessions.
- Use the original product views to compare the body and clip.
Controls and connection.
A short press of the multifunction button answers or ends a call, or plays and pauses music. Incoming-call vibration draws attention to the call; the specification also describes pairing with two devices.
- Keep the phone within the usable wireless range.
- Range varies with obstacles and interference.
Endurance and charging.
The listed battery capacity is 70 mAh. Music playback and talk time are approximately 10 hours, and full charging takes approximately 1 hour. Music and calls are alternative operating modes; the two durations are not added together.
- Charging input: DC 5 V.
- Actual endurance depends on volume and usage.
