Since i bought this track nothing came right. They fell of after several days. I got these to replace the pads on my M30s. I bought a size 5 and they were massively too big. I use my phones to monitor sound coming through a professional sound board because these have always done an excellent job of eliminating reverb and leaving just what comes through the sound board. I spent considerable time searching Amazon for a splitter that will allow me to play sound on an external speaker and still allow my kid to use the headphone/mic to interact with the teacher. Done deal. Also if you are worried because you have larger calves they did fit around my calves and mine are big but my foot slid forward when walking around the house in them so I knew these wouldnt work for me but they are just as pretty in person to bad I didnt wear them out! Also, RTA furniture isnt exactly known for its ability to endure shipping. They are very cute and seem to be comfortable for the time being.
