    I spend a lot of time on official phone calls and I was on the lookout for a wireless ear/headphone but was very skeptical if i had to charge the set everyday. I saw that this product has an advertised battery life of 17 hours and decided to give it a try. It fits in neatly behind the neck so you don't have to worry about it falling off. The sound quality is clear for phone calls and also offers decent quality for music (music aficionados beware. Not for you). The microphone is also clear, I have never received any complaints from the other side. I would not recommend it for use while running ( you may still be ok at a gym). The battery life is just amazing and it lasts me for a week or more for 1-2 hours of use a day. The only one thing is that it looks and feels very delicate so you need to treat it with care.

    These have a good bass for ear buds. The battery last me at least 2 days at work (8-9 hrs) before I need to recharge and that is with it having 2-3 more hours of charge left.

    I brought these because I needed some wireless earphones for work. I work ten to eleven hour shifts and these earphones last the whole night on a single charge. My complaint and it's a minor one, is I wish the earphones were a little louder. Great buy for the price and the charge they hold. Very lightweight also.

    Overall Good Headphones

    Overall, I like these headphones. I had never used wireless headphones but thought they might be nice for working in the yard or when out walking. I have no desire to have them in my ears all the time like my son does, so I didn't want anything too expensive. I also figured I would probably lose the truely wireless types, so these neckband headphones seemed perfect for me. The sound is fine for my use and the battery life is very acceptable. For me it is a great solution. The only thing I changed was to replace the ear tips with memory foam ones. I have never had good success with the silicone tips. The always fall out of my ears, but the memory foam work much better in my ears.

    The Best Battery Life!!!!

    Purchased to replace a set of Samsung Level Pro U and absolutely love these. Honsetly the Pro U always hurt my ears after wearing long periods but these are comfy and light weight. I use primarily while working at a desk and air travel, and don't have problems with them falling out of my ears. The sound is all-around good. The best part, and why I initially purchased, is I can go 2-3 days before needing to charge these. This means I don't have to stop listening to music half way through my day to charge. The only cons are they are not sound isolating and while on a call others have trouble hearing me. Since I use 95% of the time for music, this is not a big deal for me. Sound isolation would be nice, especially while traveling or mowing the yard but for the price I paid wouldn't expect it.

    For the price, these have nice sound and the small earbuds are perfect for sleeping with them in. Plenty of volume, and the battery life is just crazy. I've never gone below medium yet, and I sleep with white noise every night. I love that it was the "wire stoppers" so that the earbuds can't pull out and ruin the headphone. My last of this type design quit working for this very reason. One ear bud became disconnected, probably by accidentally getting pulled once too often. The only real con would be that these are a bit dated as far as design, with the BRIGHT flashing blue light, even after connecting. I put a small bit of electric tape over it so that it doesn't wake me up. Nice product so far (about 1 month)

    I switched from lg headphones (which I used for years and found myself having to replace them every 3 months.) These are so much sturdier, and have a great sound. I wear them 10 hours a day and battery life is awesome.

    If you're looking for a solid pair of wireless headphones, that have great sound quality, long battery life, durability, and when they fall out of your ear you don't immediate lose them. Then I highly recommend these! This is my 3rd pair of these, I usually get about a year out of them before the cable connecting the ear bud to the neck body portion gets a short from the bending of it over time. But the cost to value is great in my opinion. I always buy the BBY coverage on these and it's saved me twice now.

    I absolutely love these. No more cord to catch on...everything. The ear buds are comfortable, the sound is good for the price, and it is so light I forget they are on while the ear buds aren't in. The buttons are easy to use and figure out, easy to set up, and it's easy to charge. I haven't used it for phone calls, nor will I, but I imagine they'd be fine but not great.

    What I was expecting and hoping for is what i got. Nothing super fancy just a simple wired bluetooth to talk on the phone and listen to music while out as a delivery driver. Had these over a year now, they still work fine. Im out in all weather and dont cover these headphones up at all. Still working. These are not some high quality amazing headphones, but for what they are, theyre good. Battery life is good and so is connectivity. A solid choice if in the market.

    Wireless, so that's always a plus. You don't have a cord tangling you up. Perfect for exercising or just because. It stays pretty well on your head.

    Purchased these for my daughter because her Skull Candy ones finally died after 6 years. She absolutely loves them! The battery stays charged for days and she uses them daily. They are comfortable and easy to pair. She likes how if she’s away from her phone and gets a call, the headphones vibrate to alert her. The sound quality on these are so much louder and better than her other ones ever were and they cost the same price.

    Love how long they stay charged Love how far away I am able to get from my phone, and still get a good sounding play. Love I am able to wear these while I sleep. Love that I may wear these all day, and nobody knows when I am listening to something, or what I'm listening too. Love how long these have lasted me, til the speaker wires started to get all staticy and in one ear, sound comes off and on. So I went and bought another pair, cuz this pair lasted me the longest, with much convenience with their use.

    These are the best starter wireless headphones I have used so far. The battery lasts almost all day, litteral 20 hours. They have the best connection in the game. I would say I got 30 feet from my phone before I lost connection. Comfortable? Yes! I like to wear my headphones in bed while I lay on my side, and these did the job. Sound quality is mediocre but better than your average cheap headphone. These are quality in ear head phones.
