Ear plugs aren't just for noisy workplace environments. Ringing is bad. If it's slight, it may partially go away but as posted, hearing damage is incremental and other than temporary threshold shifts, it's NOT reversable.
Music stores sell plugs called 'Hearoes' and they have different attenuation levels. Some actually allow more wide-band frequency response than generic foam or silicon rubber plugs and that can make listening to music more enjoyable.
If you listen to loud music and your ears feel stuffed up after it stops, it's not safe. OSHA has exposure rules that can be seen online- IIRC, 100dB has a 30 minute/day limit.
Enjoy your music as loud as you want, but above 90dB, think about wearing plugs or limit the time.
