Plugfones® Guardian Plus™ Earplug-Earphone Hybrids with In-Line Mic (NRR 27/29)

Earphones

Found these great, very comfortable and excellent sound, with volume being better than expected.

Excellent for go karting

Clear sound. Soft in ears. Fine with a helmet over the top!

Can't live without these

These are the only way I can tolerate vacuuming and other noise. Fairly comfortable and good noise blocking.
