Who knows when I will need a short single earpiece Every week I rotate my wheels. Talk about multi-functional ????I can not say enough great things about this Product basically I am in love with it ???? Im still not fully sold on Synapse. Less auditions + better clients = win. 5Quality is not as nice as I was hoping, looks like something I can buy at fashion nova or forever 21Still cute, comfort is just ok. Ich rufe also die Seite auf und erlebe Kritikpunkt Nummero 3. I would recommend this and recently bought the second unit. Otherwise, it is excellent for use in travel. I can only say try them and if like me the soles of your feet are a bit "delicate" then these should be a great help.
