Pros:-Relatively cheap-Easily paired with phone-Music sounds great (clear with a decent bass)-Calls sound clearer/less background noise picked up than through my phone-Can wear for long periods of time without ears hurting-Don't shift around while wearing AT ALL-Nice range. Got about 50ft away from phone before music/call broke up-Have only charged three times in two weeks-Fold up and are lightCons:-Leak a ton of the music-If laying down, slightly (but not completely) uncomfortableI am a college student whose phone quality is downright awful. I make calls everyday and was tired of people telling me to repeat what I just said because they couldn't understand me. Worse they could hear other people around me better. I also listen to more music than anyone has any business listening to. What I needed then was a headset that had a better microphone than my phone and could give me a satisfying music experience. It also needed to be inexpensive. I have other money worries, so it's nice that I can buy a headset that actually works for a decent price rather than an overrated fashion statement that costs way too much money.So far, this headset delivers! I have only had the headset for two weeks but will update in another month or so.I listen to music as I walk to and from my classes all day, as well as when I sit down to study or do assignments. As any serious college student knows, that's practically all of the time. I now keep my phone in my backpack as I walk as there is no need to have it out to skip through songs. With a press of the buttons I can increase/decrease volume, skip a track or repeat a song I just heard. Pressing the call button while listening to music will pause it. As soon as I leave for class in the morning I turn the volume up entirely on my phone, and then can increase the volume further from the headset for louder music. I pause the music when I get to class and let the headset hang around my neck during class. The blue light that flashes on the right headphone does not bother me or anyone else I know of. Be aware, even if the phone is on silent and your headset is on, it will make a relatively low beeping jingle upon an incoming call. It's not loud enough to disturb the entire class but you will get looks from the people sitting immediately around you.Whether I'm studying or just taking a break, listening to music on this headset is fun! I put my phone somewhere (like on charge on the other side of my room), and don't have to worry about going out of range. I put my phone at one end of a hallway and walked away from it listening to my music as loud as it would go. It didn't break up until I was around 50ft away. For me, the listening experience could be improved if so much of the sound didn't leak out. I listen to music very loud, so when I first tried out the headset, I turned it up to my preferred volume. I then took them off and was surprised by how much everyone else would be able to hear. For me, it's not really a problem since I use them in my room or while walking to class. I could really care less whether passing students hear my music, but for others it may be a problem. The volume CAN be adjusted to where not too much music is leaking, though. It depends on how loud your music needs to be.The music is all clean too, as far as I can tell. I've run them past any genre you can think of. I was surprised by how much bass there actually was. I played a few bass test songs and was surprised by how well they did. They get really loud paired with my phone, too. They don't sound professional or anything, but they definitely sound good for what I paid for them.I wear this headset all the time. The cushions are definitely nice to my ears. Obviously, after two hours or so you can feel you've been wearing it where the headset wraps around the ear, though. I usually just adjust it, or take them off for five minutes, and put them right back on. Also, while laying down they are slightly uncomfortable but some adjusting takes care of that for me, as well.They also do not shift around! If you are like me, you kill ear buds with cords within a month. They get caught on notebooks in my pack, are pulled out while walking, etc. I like that this headset has no cords, so that should definitely help extend the life. I was worried that they would fall off or shake while I was walking around or doing things. When I first got them, I put them on and shook my head to see if they would fly off. I jumped around, bent over quickly to see how much they shifted. Nothing. These don't go anywhere. The buttons did make a slight rattle but it was hardly noticeable at all. I haven't tried running in them yet, but will have to. I do not have to worry about them coming off while walking around or doing any of my other day-to-day activities. I also like that they fold up and I can store them in the corner of the drawer. This decreases the chance of them getting tangled with other things.My phone calls have never been better. I do not think it is all just that my phone had an awful mic, either. Being in college, there are lots of social places I go to that can get noisy quickly while I'm taking a call. I am easily heard over any background noise the headset picks up. To me, they really only look like a headset for listening to music, so you get a weird look here and there before they realize you're making a call. I have gotten a compliment or two, as well. Before I purchased them, I was worried how they would look but they're really no larger than any other headset I have. If you have any qualms about the size of the headset I have posted some size comparison photos.I also haven't really charged them, unlike my phone which I HAVE to charge every day. I did the initial charge when I first bought them. I've charged them two more times since just to charge them. The red light went off after a half hour both times, meaning it didn't really need charged yet.Since my phones battery seems to drain all on its own, I was slightly worried about how much battery the Bluetooth would consume. It hasn't really made much of a difference. Listening to music drains the battery, it doesn't seem to matter whether I use this headset or another that isn't Bluetooth.I have never owned a Bluetooth headset. In fact, I've never had a use for Bluetooth until I bought this headset. The instructions were easy to follow and I paired my phone with no problems. I have a Samsung Android Smartphone. If my laptop was Bluetooth compatible I would use this headset even more.Overall, I love these headphones! I often forget I'm wearing them and they give me good-sounding calls and music--all for a good price! If these are as durable as I'm hoping, they will definitely be worth it. Some have mentioned the blinking blue light is annoying. It does not bother me, or my friends, in the least. Some have also mentioned something about the charging cable being too short. It is a standard cable and many of my other charging cables fit it. I took one from a camera I own since it's longer.
