From what I&amp;#x27;ve read, it might not be the most power-efficient format, however, and those tiny earbuds need to be &amp;#x2F;really&amp;#x2F; efficient.&lt;p&gt;But I also suspect that popular wireless codecs (i.e. Dolbly&amp;#x27;s AptX, MPEG&amp;#x27;s AAC, and Samsung&amp;#x27;s Scalable) are powered by marketing fluff.  I&amp;#x27;d love an informed opinion :D</text></comment>

Opus excels at getting good sound quality at lower bitrates.&lt;p&gt;If there&amp;#x27;s a talk or lecture on Youtube that you&amp;#x27;re about to grab, try the 50kbps Opus version and save your limited space for more important things, but you might need to remux from webm to an ogg container for compatibility.&lt;p&gt;&lt;pre&gt;&lt;code&gt;    e.g. youtube-dl -f249 $URL  --exec &amp;#x27;ffmpeg -i {} -vn -c:a copy {}.ogg&amp;#x27;&lt;/code&gt;&lt;/pre&gt;</text></comment>
