I have a right to use such a bold title because I have had about 4 pairs of these over the past six years. Der Gipfel: Auf dem Fahrrad waren sie so leise (bei maximal aufgedrehter Lautstärke), dass ich frustiert meine alten Sennheiser für 70 Euro wieder anschaltete - und diese lieferten gewohnt guten Sound in ausreichender Lautstärke. Well worth the money Tool tray is also very handy. Zur Kapazität des Akkus habe ich keine Angaben gefunden. Quality slippers with good memory foam which springs back to shape as opposed to getting a bit thinner everytime you wear them. Did not slip on the wet floors. Yes, you read that right, you can program this to support sidetone (mic monitoring) on the PS4. Cant recommend enough, and I think Ill be sticking with Redmi phones for a long time. Installed into studs.
