I usually have a hard time wearing any kind of ear plugs and ear buds. They push into my ear canal and after 20 min or so, they hurt. These were actually quite comfortable. Because of the ear hook over the top of the ear, they feel more secure and do not need to be smashed into your ear canal. I wore these while jogging for 40 minutes without any pain or ear aches. I also had them on while shopping and was pleasantly surprised by the comfort of them.The outside of the two earbuds are actually touch sensitive and can be used to pause the music or track advance with two presses of the outside. I had no issue pairing them and they always sync'd up when I was taking them out of the case. It is really nice to have an actual battery percentage shown on the case and then a flashing icon to show you the battery status of the left and right earpiece. The case is how the two earbuds are charged and the case itself can charge something else out the USB front port. However, I am not sure it would charge a modern phone to full.As for the quality of sound, it has fairly decent bass and highs. I had to adjust the sound with an equalizer to bring out the mids more to my liking, but overall, it plays music fairly well. For calls, my voice was clear to the person on the other side and they had no issue understanding me.The only item to be aware of is the semi-mirrored top. It also shows fingerprints, but it allows you to see the battery percentage with the top closed. You can also see the charge LEDs on the two ear pieces as well.When I ordered these, I was skeptic as to their comfort and quality, but I am impressed with these. They were able to stay in while jogging and did not make my ears hurt. They get plenty loud enough and still have a nice sound. I am sure you can find better sounding or longer lasting, but you will also pay a lot more for them too.
