If ANC isn't functioning properly, first ensure that your earbuds are fully charged. Check if ANC is activated in your earbuds (check product functionality for how to enable ANC mode).

The ANC quality has diminished recently. What could be causing this?

A: Diminished ANC quality can be due to several factors:

- Ear tips may not be fitting properly in your ears. Try different sizes or types of ear tips for a better seal.

- The microphones used for ANC might be blocked by dirt or debris. Clean them carefully according to the manufacturer's instructions.

I'm hearing a hissing sound when ANC is enabled. Is this normal?

A slight hissing sound can be normal when ANC is active, but it should not be overly distracting. If the sound is too loud, it could indicate an issue with the earbuds. Try consulting ACwO customer support.

Why does the ANC feature cause discomfort or a feeling of pressure in my ears?

Some users might experience discomfort or a sense of pressure due to the way ANC technology works. This is usually more noticeable when the earbuds create a very tight seal. Taking breaks from using the earbuds and ensuring they fit comfortably can help alleviate this issue.

PURE AUDIO™ ANC Technology

Active Noise Cancellation (ANC) is a technology used in headphones and earbuds to reduce unwanted ambient sounds. This is achieved using a process called active noise control. ACwO DwOTS Earbuds are equipped with PURE AUDIO™ ANC Technology that reduces the background noise when you wear the earbud and power on ANC Mode. Currently, ACwO Earbuds come with noise cancellation of up to 35db & 25db

ANC Up to 35dB:

Active Noise Cancellation (ANC) up to 35dB in ACwO DwOTS Earbuds signifies a high level of ambient noise reduction. This technology uses advanced microphones to detect external sounds and then produces inverse sound waves to cancel out the noise. At 35dB, the earbuds can effectively reduce the noise of busy city streets, loud cafes, or the hum of an airplane cabin, making them highly effective in environments with moderate to high ambient noise.

ANC Up to 25dB:

ANC up to 25dB, while slightly less powerful than 35dB, is still highly effective in reducing ambient sound. This level of noise cancellation is adept at blocking out noises from office environments, such as the sound of air conditioning, computer fans, or distant conversations. It's suitable for everyday environments where you need to reduce background noise to concentrate better or enjoy your audio content without interruptions.

Real-Life Application Of PURE AUDIO™ ANC:

In practical scenarios, 35db ANC is particularly beneficial for commuters and travelers. For instance, while commuting in noisy public transportation like metro trains or buses, these earbuds can significantly dampen the engine's roar or the chatter, allowing for a peaceful journey. Air travellers can minimise the constant drone of the aircraft's engines, making long flights more comfortable and allowing you to enjoy music or movies without the distraction of background noise. In everyday scenarios, 25dB ANC comes in handy in office settings or while working from cafes. It can help you focus on your work by reducing the distractions of background office chatter or the clatter of coffee cups. It's also beneficial for students studying in public places, offering a quieter and more focused study environment. Even at home, it can help diminish the sound of household appliances, allowing for a more immersive listening experience, whether you're relaxing or engaged in a hobby.
