Would have been okay if I just got the grease. The sound quality and volume control are awesome. The effect is really quite incredible: its like theres a special sonic column reserved for vocals and unpolluted by other sounds. 5 to a 6 depending on the shoe sometimes a 6. thats all these guys/gals specialise in. Setup to Iphone 7 Plus1. That set-up was okay for work, but I was in search of a premium audio experience for home listening. FAST SHIPPING, GOOD QUALITY. And let me just say that I am extremely finnicky. Then they worked fine.
