I was looking for a pair of corded Bluetooth earbuds with a decent sound quality (since the last pair I bought were a disappointment in that regard) and decided to give these a go. I've had them for about a month now and I really like them. I use these at work, the gym, and around the house, which often adds up to 6-9 hours of use a day.Pros: Pairing is easy. The neck loop is great if you're like me and just want to let your earbuds hang from your neck, plus with the cord length and the magnetic bud pieces they'll never fall off of you. The buds are comfortable in my ears. Sound quality is pretty solid, I especially like the deep bass. Battery life is good, I can leave these on for hours even if not listening to anything and there's still a good charge left at the end of the day.Cons: The volume always starts in the middle range each time you pair them and it's LOUD, so you always have to remember to turn it down before you start playing something. Even the lowest volume setting can be juuust too loud in quiet environments. The control buttons are on the left side, so if you're used to them being on the right like I was it takes some getting used to.

I work 8-11 hr days and needed a set of headphones connected to just my tablet for music, so i wasn't after the clarity of the mic or voice calls, so you may want to read those reviews if that is your main focus. The battery life on this is great for my needs as i can play music from my tablet from 630am till 7pm straight at 60-75% level range with 5 additional hours to spare before needing a charge. Typically i am at 40-55% level range so i can go almost 3 days at 10hrs a day full use with just music playing. "Side note, i know first hand you cant hear anything outside of the these as our office fire alarms (extremely loud horns) were going off (testing that day) and the only way i knew they were running was the flashing alarm lights on the walls were also going off. When i took these off, i realized i had bought a great set to listen to music, but may need to lower my volume lol.I really really wish this company made over the ear headphones (good ones that are comfortable for the above uses) as i would gladly pay more to have that option. Regardless, these headphones are very much worth it for my use and hopefully they can be for you as well.I highly recommend reading at least 30 recent reviews so that you can get a better feel for the overall quality of the product, but keep in mind, sometimes (as we have all experienced in life) we get stuff that is a dud or damaged from the manufactures bulk development and shouldn't rate the product solely on that, (like many here do) or due to your own lack of understanding simple/basic instructions, so please when you are contemplating a purchase here or anywhere, rate/review these and/or others as its overall performance, as not everything is equally the same (which is why we have tons of options to purchase from in this world).

No puedo dar una opinión favorable o desfavorable porque tuve que devolverlos a la semana de recibirlos por un sonido de interferencia que se escuchaba, no sé si el sonido sea por algún defectos de fabrica o llegaron dañados por algún mal manejo. le doy 3 estrellas por el tiempo que los use la batería si tiene una larga duración lo cargaba cada dos días usándolos de manera continua, son cómodos y no me molestaban al usarlos largo rato.

If you like over the neck style headsets, then this is a solid choice. I mostly use these to listen to audiobooks, and the sound quality is great for that, and quite acceptable for music. Some reviews complain about call quality, but didn't have anyone complain that they couldn't hear me when I used it The battery life is awesome. The battery never ran out before the end of the day even when I was listening for most of the day. The build quality seems good, and I didn't have any issue with speakers going out or wires breaking (like you often see with devices like this). I only had one issue. The reception range was awesome for the first six months, but then it started getting shorter and shorter until I had to hold the phone within a couple feet of the headset to have a good connection. I actually opened the device up, and isolated the problem to the main bluetooth chip on the board. I found another bluetooth headset that my son threw away with the same chip, and pulled that one off and soldered it to the board. Worked like a charm. So I'm not sure if these are poor quality bluetooth chips or if this was just a fluke.Unfortunately I lost this set (left in the emergency room after a recent visit), but they were good enough for me to give them another try. Just ordered a second pair.Update: The charge port on the new pair I bought quit working after about a month of use. I popped off the cover and both power pins had pulled loose from the PCB. I was able resolder the pins to the board and added some extra solder to try and prevent this happening again. Original solder was pretty minimal. Be careful when plugging and unplugging these!Another update: I'm back to buy a third pair of these. The second pair lasted almost a year, and still works, but one of the ears is going out. I did eventually have to replace the charge port, so be aware that that is a potential weakness of these. Still, the performance is very good when they're working as intended and I have the skills to fix problems like this if necessary so I'm sticking with them. Hopefully third time's a charm and these will be trouble free!
