FURTHER UPDATE, FEB 2021I have experienced pairing issues with my E8 v3. Ich habe mir die Schuhe gekauft, da ich dachte endlich mal etwas schickere Outdoor Schuhe und von Teva da kann ich nichts falsch machen! Awesome book! Love this and work with it frequently IEMs produce far more detail in recordings but cant compete in the depth of bass. Does its job well3. No feeling like Ive been wearing a vise. I had to replace an older BT headset adapter, which is no longer available, that eventually died. Every time I tried to take a step, my foot would slip off the sides of the memory foam. Mine is honestly the worst I’ve seen in person.
