Why Small Speakers Can Sound Distorted at High Volume

A phone or laptop speaker can sound clear at moderate volume but become harsh, buzzy, or less detailed near its maximum setting. Turning the volume up asks the speaker to produce stronger sound, but a small speaker has limited room to move and limited electrical and thermal capacity. The useful mental model is simple: a speaker has a working range. Within that range, it can follow the audio signal reasonably well. As the system approaches its limits, the output may stop matching the requested signal as closely. That mismatch is heard as distortion.

What Spatial Audio Does and Why It Can Sound More Immersive

A pair of headphones has only two earpieces, yet some films and games can make a sound seem to come from in front of you, behind you, or somewhere above you. Features labelled spatial audio, 3D audio, or virtual surround are designed to create that impression. The useful idea is simpler than the names suggest: spatial audio tries to reproduce some of the clues your hearing normally uses to locate real sounds. It does not literally place a speaker behind your head. Instead, the playback system changes the sound reaching your ears so your brain can interpret it as coming from a particular direction.

Stereo vs Mono Audio: What the Difference Means When Listening

Put on headphones and play a stereo recording, and one sound may seem to come from the left while another sits toward the right. Switch the same device to mono audio and that left-right separation can disappear. The difference is not simply that stereo sounds better and mono sounds worse. Mono and stereo describe how audio channels are used. A channel is a separate audio signal. Mono uses one channel for the program, while stereo uses two channels, conventionally called left and right.
