UPDATED 7/7 - they died. Will no longer charge. Prob used them a dozen times. Major thumbs downDesign: 9/10 - they stay put, wire in back of head is comfy and works with ball cap and shades no prob. Lightweight.Sound: 6/10 - get the job done, I think Apple's reg white corded headphones sound better but could be losses with Bluetooth. 3 sizes of silicon tips are included, experiment with all 3 for best sound, too small there will be no bass, too big and you'll hear your footsteps inside your head (you'll know what I mean when you try)Value: 10/10 - picked these up "like new" for $25. For what they can do, great deal.

Update. The right ears are not working on all 3 pairs. Disappointed.For the price, I can't complain. Had the powerbeats2 for a few years until the rubber on the volume control rubbed off. Comfortable positioning and pressure is not intrusive. If you plug in the micro usb to power up without turning off the headset first, when you unplug the micro usb, it was auto connect to the last device. The power button is raised higher than the volume which comes in handy. I bought these as well as the Taotronic and prefer these.Update: it started to make clicking noises and now has a high pitch ring in the background.

Updated 4/12/19:Bought another set that had the same problem and ended up buying the replacement since I like these more than other earbuds because of the weight distribution. Anker support has gone downhill as they no longer feel like honoring the warranty. I have two sets with one defective after repurchasing it at the end of January and getting a replacement. I contacted support where they ask me the serial number multiple times and prolong the replacement process. No longer buying Anker. Keep the funds of the replacement and lose a customer. Plenty of other products that work well for cheaper. The main value add was the support but it seems that is no longer the case.Update 2/19/17:After I posted this review, Anker contacted me and offered to replace the broken pair. I was traveling and they were able to send it to me where I was. I've waited to post an update since I wanted to make sure the new pair would hold up. I'm glad to report that they are still doing well. I've updated my review to reflect the new pair.I would up it to 4.5 because of the extra service. There's still some drawbacks but that is more with the unit. I like anker products and will continue to buy them for as long as they stand by their products.------ Original ReviewI typically buy anker products because they are pretty good quality for the price but this time it wasn't so great.I would like this if it continued to work. I use this regularly working out at the gym and cycling. I purchased this in late Aug and it is not Dec and the left speaker no longer works.Sound quality is good with good all around range. It feels a little bulky, good outside noise isolation. The only real problem is the left ear audio went out. Battery life is a few hours on 1 hour charge. No bluetooth syncing/pairing issues to iphone 6plus/7plus. The buttons are a little small for the volume control when you are actively working out. It would be nice if they had volume up on the right volume down on the left or something like that. I don't know how practical that is.:(Battery: 8/10Packaging: 9/10Sound Quality: 8.5/10Durability: 2/10Pairing: 10/10Noise Isolation: 8/10Fit/Feel: 8.5/10 (a little bulky)

These earbuds arrived within a decent period of time. However they were defective and never worked. I thought I had done something wrong when trying to pair them, but after speaking with Anser and online testing at their direction they determined they were defective. Do not buy anything from "Alwayz for sale", you can't contact them by Email or phone. Very disappointed Tanga would deal with them. Am reconsidering by buying from Tanga as a result.

Suck

the good- sound quality is excellent.the bad- rubber end piece that goes in ear kept falling out after about a month of use. I lost one of the ear rubber pieces. Can't even use it now.

Broke apart in two days. Zero. Who made this.

Had these for two weeks. Enjoyed them while they worked. Yesterday the LED light began shining purple (ordinarily glows blue or red, no purple light per their documentation). Now, will not charge, will not turn on. My previous Anker purchase was an LED flashlight that was DOA. I must question their quality control. Will not be purchasing another Anker product.

They skip all the time. It's hard to run when I have to keep stopping and reconnecting to my iPhone 6.

I like the sound quality and comfort, but they stopped charging after only one month and now they are useless.
