Frequently Asked Questions - BTH-W150ANC AKAI

How do I turn on the AKAI BTH-W150ANC headphones?

Press and hold the power button for about 2 seconds. The blue and red lights will flash alternately, indicating the headphones are on and in pairing mode.

How do I pair the headphones with my phone?

After turning on, the headphones enter pairing mode with red and blue lights flashing. On your phone, search for Bluetooth devices and select 'BTH-W150ANC'. Once connected, you'll hear a voice prompt saying 'connected' and the blue light stays on.

How long does the battery last?

The battery provides approximately 13 hours of music playback time. Charging takes about 1.5 hours via the USB Type-C cable.

How do I use the active noise cancellation (ANC)?

Press the ANC button to toggle noise cancellation on or off. Note that ANC works best for low-frequency sounds like engine or airplane noise. It may not be effective in quiet environments.

Can I use the headphones while charging?

The manual does not specify if wired playback is possible during charging. However, when you connect the 3.5mm audio cable, the headphones automatically power off, so Bluetooth is disabled. Charging is recommended with ANC turned off to avoid green LED indication.

What does the NTC charging protection do?

NTC (Negative Temperature Coefficient) protection monitors battery temperature. If it exceeds a safe limit (typically 45°C), the charging circuit is disconnected to prevent overheating, overcharging, or damage.

How do I adjust the volume or skip tracks?

Short press the volume up button to increase volume, long press to skip to the next track. Short press the volume down button to decrease volume, long press to go to the previous track. You'll hear a beep when volume reaches maximum or minimum.

Can I use the headphones wired?

Yes, you can use the 3.5mm audio cable for wired connection. However, when the cable is plugged in, the headphones automatically power off and all buttons become inactive. Only audio playback is supported via the cable.

What should I do if the headphones don't connect automatically?

Ensure the headphones are in pairing mode (flashing red/blue). On your phone, forget 'BTH-W150ANC' and re-pair. If still not connecting, charge the headphones fully and try again. The headphones will auto-turn off after 5 minutes if not connected.

How do I clean the headphones?

Use a soft, dry cloth to clean the surface. Do not use harsh chemicals or detergents. Avoid getting liquid into the ear cups or charging port. Ensure the headphones are dry before charging.

6. Noise cancellation key (ANC)

Noise-cancelling technology cannot wholly isolate sound due to the air trapped between your audio device and eardrum. However, the air is essential for you to hear music. For using this function, please remember the following:

The noise cancelling effect may not be pronounced in a tranquil environment, or some sound may be heard. If there is little ambient noise, it is even advisable not to switch on the NC function, as it needs ambient input to function optimally.

Noise cancellation does not transfer during telephone calls. Although it protects the headphones user from the surrounding noise, it does not apply to the receiver of the call: they will potentially hear background noise.

Depending on how you wear the headset, the noise-cancelling effect may vary, or a beeping sound (howling) may occur. In these cases, take off the headset and put it on again.

The noise cancelling function primarily works for noise in the low-frequency band (train, airplane, engine noise). Although noise is reduced, it is not cancelled altogether.

When you use the headphone in a train or a car, noise may occur depending on environmental conditions. It is not advisable to wear noise-cancellation headphones while driving, as taking notice of traffic sounds is essential for your safety.

Mobile phones may cause interference and noise. Should this occur, locate the headphones further away from the mobile phone.

Do not cover the microphones! The noise cancelling function or the Ambient Sound Mode may not work optimally, or a beeping sound (howling) may occur. In these cases, take your hands off the headset microphones.

7.Low battery

When the headphone power drop to 3.3V, the headphone red light will flash 1 time in each 3 Seconds until power off.

8.Connection timeout

When the headphones are turned on but not connected to Bluetooth, they will automatically turn off after 5 minutes.

9.Charging

When using the Type C cable for charging the headphones, the red light will be on. Please make sure the noise cancellation button will be turn off, otherwise, the led will be green. Once the headphones are fully charged, the red led will turn off.

10. Battery Safety Instructions

Improper battery replacement can be an explosion hazard and can only be replaced with a battery of the same type or equivalent.

For products with removable batteries, the batteries must be recycled or disposed of properly. For products that are not removable, disassembly is prohibited.

Battery is not allowed to be disassembled, impacted squeezed or put into fire. Do not expose the battery to conductive materials, liquids, fire or high temperatures.

Note: Any attempt to remove or replace the battery will damage the product and affect the product's warranty.

*When the earphones are lack of power, please charge earphones immediately to avoid affecting battery life.

11.NTC charging protection (Negative Temperature Coefficient)

NTC circuit is designed on the PCBA board of the headphones to provide charging protection. When the NTC circuit measures that the battery temperature exceeds the preset safety range (usually 45 degrees), the PCBA board will protect the battery from overheating, overcooling, or being affected by excessive temperature based on the set protection mechanism, such as disconnecting the charging circuit, stopping charging, etc., thereby reducing safety risks.

12. Usefull Safety Instructions

1. To avoid hearing damage, keep the volume at a moderate level. Avoid listening to music at high volume for long time, which can cause permanent damage or hearing loss to your hearing.
2. Please do not use the headphones in situations that require your attention, such as driving, cycling, crossing the road, etc.
