I'm super impressed with these Sinoideas earphones. The noise cancelling/isolation works great and the bass is incredible and allows you to really enjoy the sound. I'm not a techy person but I can tell a high end well made set of ear phones and these fall into that category. The earphones come with extra ear cups and designs so you can find the perfect fit for your ears. Once you find which one is comfortable for you, then you can decide if you like wearing them over your ears or allowing them to hang freely. I personally like the over the ears method because it takes the weight off a bit. The microphone/remote works great and I tested it out by calling a friend who said they could clearly hear me with no delays. I was also able to move through my playlist with ease. The earphones come with 3 sets of cups (s, m, l), the manual and a shirt clip. All the plugs and wires are solidly attached and were easy to immediately use with little need for instructions. Great set of earphones for all uses.
