Beim Schreiben auf dem iPad gibt es keine Verzögerung und es fühlt sich an wie das Schreiben auf Papier. Im not very picky about the sound, so you might think differently if you are really attuned to the music. no joke. As such, I dont use the SRS function at all and the noise reduction is amazing when used with audiobooks, or even just to dampen down the ambient noise at work (I have an air conditioner that I was just used to, but these things chop it out almost entirely when in their active cancelling mode - its eerie! The shoe bed lining is detaching from the bottom as shown. One feature I also like is that in the application you can press the green circle and it gives you an indication of the signal strength (full strength would be a full green circle, a poor strength would be 1/8th of a circle) so you know how far away the tile is. Unfortunately for me, it was not. Im still not use the arch, its not hard or too soft. Ive worn them from morning to night with no issues, theyre so great! When I have them on and someone asks me something, or talks to me, I have to lift off one side and free that ear so I can hear!
