Setup and Connectivity
The ANSTEN K2 headphones utilize 2.4 GHz wireless technology for a stable connection with no lip-sync delay. The transmitter supports multiple audio input options for wide compatibility.
Initial Setup
- Connect the included adapter to the wireless transmitter & charging base and plug it into a power outlet. The LED indicator on the base will illuminate.
- Place the K2 headphones onto the charging base. They will automatically power on and connect to the transmitter. The LED on the headphones and base will turn solid blue once connected.
Connecting to Audio Source
The transmitter supports Optical, RCA, and AUX 3.5mm audio inputs. Choose the connection method that best suits your device (TV, PC, laptop, DVD player, etc.).

1. Optical Audio Source Connection
Use the included optical cable to connect your TV's Optical Audio Out port to the Optical input on the transmitter base. Ensure your TV's audio output settings are configured to "Optical" or "PCM" mode.
2. RCA Audio Source Connection
Use the included RCA to 3.5mm cable. Connect the RCA (red and white) plugs to your TV's Audio Out (L/R) ports and the 3.5mm jack to the AUX input on the transmitter base.
3. AUX 3.5mm Audio Source Connection
For devices with a 3.5mm audio output (e.g., headphone jack on a TV, PC, or mobile device), connect a 3.5mm audio cable (not included) from your device's audio out to the AUX input on the transmitter base.
Once connected, the headphones will automatically receive audio from the selected source. The 2.4GHz wireless technology provides a range of up to 100 feet (30 meters), even through walls, ensuring a stable signal without static.

The 2.4GHz wireless technology ensures a steady signal and strong penetrability, allowing you to move freely.
Operation
Power On/Off
- Automatic Power On: The headphones will automatically power on when lifted from the charging base.
- Automatic Power Off: The headphones will automatically power off when placed back on the charging base.
Volume Control

Adjust the listening volume using the roller volume control located on the right earcup. Roll it up to increase volume and down to decrease volume. This provides precise and smooth volume adjustments.
Balance Control

The ANSTEN K2 headphones feature a balance control knob, typically located under the right earcup. This allows you to adjust the volume balance between the left and right ears. This is particularly useful if you have different hearing sensitivities in each ear, ensuring a balanced audio experience.
Additionally, a microphone button is available to temporarily amplify ambient sounds, allowing you to hear conversations nearby without removing your headphones.
Audio Modes (EQ Settings)

The headphones offer 5 distinct audio modes, powered by a dedicated DSP audio decoder chip, to optimize your listening experience. These modes can be selected by touching the designated area on the charging base:
- Normal: Standard audio profile.
- Bass: Enhanced bass for richer low-frequency sounds.
- Voice: Optimized for clear dialogue and vocals.
- Treble: Enhanced treble for clearer high-frequency sounds.
- Bass+Treble: Combines enhanced bass and treble for a more dynamic sound profile.
Charging
The ANSTEN K2 headphones offer convenient charging methods:
- Charging Dock: Simply place the headphones onto the wireless transmitter & charging base. The headphones will begin charging automatically.
- USB-C Connection: Alternatively, you can connect the headphones directly to the included USB-C adapter for charging.
A full charge takes approximately 3 hours and provides up to 12 hours of continuous audio playback.
