[4.0] These earphones are great overall. There's a bunch of different sized ear pieces to fit any sized ears. I chose not to use those wing tips. They're nice and soft and fit well, but it started to hurt the bump right above my ear canal when on for a long period of time. I don't know if it's because I have weird ears or not. But even without the wing tips, they still stay in my ears. I used them running and they don't jump around much and they never fell out. They sync with the iPhone very quickly and easily. The only problem I've had is with my Apple Watch. When listening to my music directly from my watch, the connection would go on and off very often and sporadically. If you're going to use it with your watch only, then I'd avoid buying this. The sound quality is pretty good. I'd say it's a good flat EQ. Not too heavy on the bass and treble which is good in my opinion. I take these everywhere. I just leave it around my neck. Charges very quickly. It's great.

[Lithium-Ion] I use this Bluetooth headset for everyday use and workouts. Very comfortable and flexible to take everywhere with you.

[0.395 lb] at first the ear-tips bothered my ears after a day or 2 it adjusted and haven't had a problem since. i love it. the sound and portability is definitely worth the price. i did see some reviewers mention the wire sometimes stands out awkwardly and isnt round to the shape of your face as the pics suggested, in my experience after a couple of days i learned how to put it on right it should be in shape. (i did have the typical Bluetooth issues like cutting off now and then but i'd rather have that than untangling a wire :) )

[Lightning] Since I got my Iphone 7 I am looking for earphone that fits my need. I bought 3 or 4 wired and bluetooth. I bought this one telling myself lets try the beats X since it is suppose to be made for the Iphone. The first connection is so easy that I could not believe it, you switch on the headphone and then appear a window asking you if you want to connect the headphone to your phone and that' it. It comes with four different ear adapters and two kind of wing that help keep the buds in place. It is very comfortable to wear and use and sit very well around the neck, no weight is felt on the ear from the battery. The battery can last 8 Hours and for now it has been enough for me. Some people seems not to like the case made for the headphone but personally this is perhaps the first one that I can use without any problem you just have to roll it correct way. Regarding the sound quality I am not an expert but it sound fine well balanced to me .

[Cable] These are a fantastic Bluetooth headset for someone on the go. They shut out all other sound very well with the silicon ear tips. The battery life is so long I haven't run them down yet. They sit securely without any need for the wings that are included. And they are small enough to actually hide in your collar if you don't want to look like a complete tool, unlike an LG headset. The only downsides are the carrying case is utterly useless and some of the time when moving around you'll get noise through the wire from the headset moving around against your collar.

[Lightning] One of my favorite ones I ever try, easy way to conect and they dont fall when runing and doing any activity.
Such a good product tou get for your money.

[8 Hours] I bought these as an upgrade to the plastic version, which I broke. And the metal construction and rubber finish and it makes all the difference in the world

[4.0] I've had the Beats Studio wireless over-the-ear headphones for over a year and desired the same audio quality in a more portable form. These earbuds do not disappoint. If you're looking for noise-cancelling earbuds with the freedom of bluetooth then these are worth the purchase. The battery life relative to the recharging time is also very impressive.

[Cable] Works fine right out of the box. First, I charged it up. Then ran the Bluetooth hook up to an android tablet with immediate connect; then linked it to a Windows 10 phone with immediate connect. The sound quality is very good on both tablet and phone. I have not used the microphone on either. Very compact; notably smaller than the PowerBeats and the Studio Wireless by Dr. Dre. Very convenient to carry. I recommend the B&H recommended Mophie 1400mAhave compact travel case to replace the smaller one that comes with either the BeatsX or the PowerBeats. It also keeps the Beats fully charged.
