I use mine to help me sleep, so comfort was important to me. Before I understood how to wear these, I thought they were uncomfortable, but when I read they are designed to be worn with the cord going up and around the ear, worn properly, they are more comfortable than any earbuds I have ever worn while sleeping, plus, this over-the-ear design ensures a snug fit that enables experiencing the incredible deep bass these earphones allow you to hear. Be sure to make use of the Android/iOS switch so the unit works correctly with your phone or tablet.I purchased mine in November of 2018, and have used them every night since then. Previously, the longest any earbuds have lasted has been three months, with many cheaper "unbreakable" sets lasting less than one month. I am apparently very hard on my earbuds while I sleep. Today, May 1st, 2019, I thought I had finally broken them when the right channel stopped producing sound. However, I was able to troubleshoot them because the earphones can be detached from the cable, and I discovered it was the right earphone that was not producing sound, and not a cable problem. I followed the maintenance instructions, taking them apart and cleaning them, and suddenly, these earphones work as flawlessly as they did when they were new. Of all the "unbreakable" sets I have purchased in the past, this is the first set that has proven to withstand the abuse I give them, and SHURE doesn't even advertise that aspect of these high-quality earphones.It disturbs me to read so many negative comments about these excellent earphones. I suspect the people complaining did not read the instructions to understand how to use them, because I had similar misgivings about these earphones when I first received them until I read the directions. $99 is a lot to spend if you are used to buying cheap $10 earphones, but used properly, they are so superior to any I have ever tried (including several "unbreakable" $60 earphones) that if these do ever finally break, I'll be replacing them with the same thing.
