TuneSound tube filter

TuneSound™System tube filters are needed for HYPƐAR™Sonic earplugs model Superior. You can easily change yourself to which pipe filters you want for each occasion. Minimum pipe diameter [mm] in pipe filters. The smaller the pipe diameter, the fuller the base. With increased pipe diameter, you hear more ambient noise. The safer choice if, for example, you are going out and exercising in urban traffic. You also don't have to take out the earplugs if you need to have a short conversation.
