Question 1

can you use only one bud at a time as I tend to do in bed

Accepted Answer

Hi falih,

You can remove one headset unit from the charging case and use the headset unit by itself. In this case, only the headset unit that has been removed from the charging case will turn on: https://cutt.ly/96UPJup (copy and paste the link into your web browser).

Question 3

Are these earbuds comfortable enough for all night use?

Accepted Answer

They are comfortable for most of day.
But I rather think they would fall out at night.

Question 4

Should the noise reduction cancel all the noises or is it normal that even if quieter I can ear all the noises when the music is not on?

Accepted Answer

Hi Giovanni,

The noise cancelling circuit senses outside noise using built-in microphones and sends an equal-but-opposite cancelling signal to the headset. By producing this countersignal, your headphones block a large part of external sound sources. However, it's important to remember the following:

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

Sound can only travel if there is a medium to transport it, such as air, water, glass, or metal. If you stand in an empty room with a speaker playing music, you will hear the music. However, if the air from this room is removed, the speaker will still function, but you won't hear any sound as there's no medium to transport the sound waves.

You may hear external sound when using Noise Cancelling due to:

-Air trapped between your audio device and eardrum.
-Different pitch levels. Noise cancelling works best when the ambient noise is low or medium in pitch and remains constant. For example, an airplane engine produces a low-pitched, constant sound, meaning that the level of sound you hear remains consistent. Conversely, when someone speaks, sound waves scatter based on the volume and energy created by every word. Unlike a plane engine, speaking pitch changes frequently. That is why you might hear someone talking next to you.
