Everyday and work use

At home, earphones serve calls, music and video; speakers serve rooms. At work, earphones serve calls and concentration, and speakers serve meetings and presentations. The same product family serves both, but the requirements differ: call clarity matters at work, while room coverage matters for speakers.

Sport, travel and public use

Sport use needs fit and sweat resistance. Travel use needs noise reduction and battery life. Public use — shops, gyms, events — needs speakers that cover a space. Each use is covered in more detail in the type guides linked from the category pages.

What this overview does not do

This overview adds no new product claims. It only organises the uses already described in the earphone and speaker guides, so a buyer can see the whole audio line at a glance.
