An Ogg file won't play on an iPhone, in iTunes or in your editor. Telegram voice messages (.oga), WhatsApp voice notes (.opus), and audio from Linux apps and games are usually Ogg.
A 4-minute OGA at 128 kbps is about 3.7 MB; as an MP3 at 192 kbps it's about 5.5 MB. For a voice message, 128 kbps (about 3.7 MB for 4 minutes) is more than enough.
192 kbps (the default) for music — Opus is efficient, so MP3 needs more bitrate to keep up. 128 kbps for voice messages.
Every phone and computer, including Apple devices and apps that don't open Ogg files.
