Los Sony dan 30 horas de batería a volumen medio con cancelación de ruido y 38 sin él, mientras que estos Sennheiser dan unas 20 horas con cancelación de ruido y 30 sin él (Aunque es probable que sean menos por el tema de que al tener que subir más el volumen la batería se reduce). I have an average size foot--not narrow and not wide. I had high hopes, but beyond running small for the size, the foot cushion surface was too flat and rigid to be comfortable, especially for a sandal. Dieser Schuh ist einfach klasse. I know right? I couldnt believe it either! For my application thats just fine but if youre going to use it in an area with a lot of potential impact you might want the strength of metal. So I leave my glasses off, or balance them inelegantly on top of the earpads. Picture: iPhone SE 2020 with case installed. My previous Sennheiser headphones lasted me five years and while I am loving the audio quality of this pair, the consistent mic input cut-off issues are a huge letdown ESPECIALLY since Im experiencing this only 2-3 months after purchasing. There is an upcoming toga event and many of the actual costume type greek sandals looked cheap and flimsy in pictures and so was hoping to find something that would def be a gold strappy sandal for the toga party but also could be used in the future for every day events too.
