There are examples here which worked out-of-the-box for me in Chrome:

In my listening opinion with very good isolated headphones: the music is very good but you can hear the drop-off of the highs in the vocal examples. It's good but not good enough for 'professional' use at the lower bitrates.

I have no idea what that is supposed to mean.

Audio compression is generally not used for production audio (film sound, television etc), but on occasion they'll use MPEG2 for remote transmission. This is a lossy codec but sounds better than the example provided, albeit at 128kbps so I'd need to hear the Opus codec at 128kbps to compare.

MPEG2 isn't an audio codec, it's a suite of standards. But based on my experience writing hardware encoders for this use case, you're talking about MPEG1 Layer 2 audio.

Opus outperforms that greatly, but it's not going to outperform MPEG1 Layer 2 at 256kbps while only outputting 64kbps itself. (Will likely need >= 96kbps for that).
