They are very, very different headphones. It runs so smooth and flawlessly compared to series 1. I got this tack so I could hold my products when I do pop ups and events. Very Nice I have a high arch so was hoping. Yes Gucci actually makes glasses made in Japan I spoke to Gucci HQ in San Francisco California and they told me the reason why the glasses come from Japan Because the quality of the glass is better from Japan and so they manufacture them in Japan by Gucci from Gucci manufacturing facilities in Japan. The reason for the three stars is because the key hole came out on two sides of the bars. But all in all theyre really good for what you pay, best bang for your buck IMO. I bought these for wearing around the kitchen, to listen to shows, podcasts, movies, etc. Kompatibilität:Ich habe das Headset auf Windows 7 32 Bit, Windows 7 64 Bit und Windows 10 64 Bit getestet - läuft auf allen diesen Betriebssystemen einwandfrei.
