Pros: Extremely comfortable, does not obstruct movement, light weight, awesome battery life, great sound quality, allows full control of paired device including music, text messaging and telephony, built solidly enough to survive a construction worker all day long. Very worth the price.

(Edit: Finally managed to damage mine sufficiently enough to justify a replacement, after 7 straight months of 40+ hour a week use on construction sites doing heavy manual labor and in temperatures ranging from the low 10's to 100+ deg F, plus rain, snow and wind of all types. Typical headphones last anywhere from a week to a month under the rigors of these conditions. Absolutely worth every single cent, I am definitely buying another set.)

Cons: Internal battery is not replaceable, wires connecting the earbuds vulnerable to physical damage, earbud tips can fall off. (Edit: Point of failure was definitely the exposed earbud wires, still buying another set)

Other Thoughts: I have owned dozens of wired and wireless headsets for mobile devices and desktop computers and I can find no better headset for mobile devices then LG has designed.

Construction workers like myself are really the torture test of any technology, and so far, neither I nor my fellow construction workers have managed to damage ours.

Pros: Fine fit. Charges quickly.

Cons: none.

Other Thoughts: If it broke I would order another one tomorrow,

Pros: Thus device sits comfortably, and I do t often notice myself still wearing it. the default earbuds are also made of an atypical material which sits in the ears very well. The buttons on the device are easy to navigate as well.

Cons: My device must have faulty internals, because after a few songs the device itself is stuttering playback. I have tested the device on multiple machines and tried multiple devices to confirm. This device seems to buffer incoming audio but then play it back with a stutter. This will develop and not go away until I restart the device, but it won't take long to become a problem again. But it will take a call just fine. The door for the micro USB port could also do with a redesign, without mails its nigh near impossible to pry open

Pros: The best model for the LG line

Cons: Terrible bluetooth connectivity

Other Thoughts: I loved my last pair, they lasted forever and held up to the gym like a champ, however this pair after 30 days skips like an old school discman. It is so annoying I really can't use them. I wanted to return these but I couldnt find the box.

Pros: Quick delivery.

Cons: These headphones arrived used! There was earwax in the earbuds! And the packaging appeared to be tampered with. Very disappointing! This is a Heath violation! I worked in Best Buy customer service for years. You cannot resell opened headphones!!!

Pros: Look nice
Shiny
Shiny box

Cons: Terrible control design
Teeny tiny manual
No online manual for this model at LG

Other Thoughts: I know a lot of people give this headset positive reviews but I couldn't get past the control design to care about their sound or battery life. Black on black controls with no tactile feel and totally out of sight. I already have a set of buds that by the time you find the talk button the caller is long gone. I decided to end the relationship and send them back.

Pros: Design looks nice took getting used to wearing. I prefer sport style earphone pieces.

Cons: As with all in ear plugs they fallout when trying to exercise or when sweating occurs. I could not get it to connect to my Samsung 5 phone. Laptop and LG phone no problem.

Other Thoughts: I could not honesty recommend them to anyone as they do not perform to my standards or my expectations and that my be my problem.

Pros: These headphones would be great... if they worked all of the time.

Cons: The headphones get choppy and disconnect from bluetooth on my galaxy note 2 phone. When I make a phone call with them, the headphones will disconnect from my phone and tell me that the call has ended, but the phone is still on the call and if I want to use the headphones, I have to reconnect them to the phone. I plan to return these if possible, but I think I threw away the packaging, so I'm probably out of luck.

Other Thoughts: I've done some research, and a known issue with them is the microphone turning off when you switch WIFI connections, but that is not the problem I'm experiencing. Not that it's okay that they have the WIFI problem, but it isn't what I'm running into.

Pros: Items ordered were as described and shipped promptly. Great Exchange!

Cons: None

Pros: I was looking for a headset to wear at work so I didn't need to have a cord running from my phone, across my desk, and into my ears. I was just tired of reaching up to my mouse or keyboard, snagging the wire and ripping the phone off my desk. This headset has been absolutely perfect to resolve that issue. Not only does it look good, but it sounds great (for the price) as well!

If you work in an office environment like I do, this may be extra beneficial to you. Since my work attire consists of collared shirts, I can simply place this around my neck and tuck it under my collar for a discreet listening experience. I simply run an ear bud up from under my collar and I'm ready to rock. In regard to the battery life, I listen to music for a solid 7-8 hours a day with these at a high volume and when I get home I'll probably still have at least half the battery left.

The sound quality is above par for a headset in this price range both in terms of calls and music. The highs are high, the lows are low, and nothing is overwhelming. Obviously this isn't a $400 set of headphones, but to me they are better than most in this range. Unlike other bluetooth headsets, I like that I can have two earbuds in during phone calls and that really helps to quite the outside world so I can focus on the caller. Also, my dad has one of these and he drives a fuel tanker for a living. I've been on calls with him as he was driving and as far as I can tell, he might as well be at home on a landline. The microphone is great at not picking up outside sounds.

Cons: None that I've found yet.

Other Thoughts: I have not at all been disappointed with any aspect of this headset so far. Set up was straight forward if you've ever set up any other bluetooth headset. And as always, newegg shipped quickly!
