Great noise isolation

My biggest complaint on most bluetooth earbuds is the noise you hear as the wire moves back and forth over your neck - I have not noticed any noise with these

For the price they are excellent, not much noise cancelling or blocking

Comfortable ear buds that isolate outside noise very well

I sometimes ride in new york subway and the bass is almost non existent because of the loud subway noise

They had issues connecting to my phone from the beginning , and also had random static/popping noises starting about a week after I got them.

Prior to the earbud breaking, there were continuous static noises coming from the left earbud

Sound quality is on-par with what you'd expect at this price range if not better, it sounds pretty much as good as my $40 wired earbuds, and the seal is good enough to impede most background noises

When on a call there's a humming noise or noise period every time I speak while using the set that the other party complains of hearing during the entire call

When I wear them while working out at the gym, if I got any sweat on the earbuds, then I would get a static noise which is unpleasant

3/4/2018In a span of a week of editing my review to mention the static noises from the earphones, Anker contacted me and offered me to send me a replacement free of charge

I did encounter a small static noise problem, but Anker support did their best to solve this issue.

They are comfortable, and even block outside noise very well

[Drawback: wired buds]Other problems are the buds randomly losing connection to my phone mid workout (iphone X and 5s), or sometimes turning into incomprehensible garbled bass noises after

Fits very well on the ear, comes with extra silicone buds for even better personalization, length is perfect, magnets are strongBad: constant static noise in the background, Bluetooth connection is poor (even when the phone is in my pocket), the battery is weaker than described, the microphone is terrible - cannot be used in conversationOverall - I would not recommend this product (would have preferred to pay an extra 30-50% and have the static noise & microphone issues fixed).

Negative:- the other side cant hear me well due to a weird fan noise that is produced by the micUpdate:Customer support contacted me and sent me a new headphone that worked as intendedAdd +2 stars

Great noise isolation

The case is large enough to fit the charging cable and the headphones, which is handy.- Noise isolation

Great for the gym, has great noise isolation and sound quality

Bad sound quality and weird noise intermittently

Because of how they sit, they provide for exceptional noise isolation

Comfortable ear buds that isolate outside noise very well

Haven't tried taking a call in the car to see how well the noise-canceling mic works

It has some static noise at times, the range of bluetooth connectivity is not great compared to others, and when the buds click together magnetically, it does not pause the media playing on the phone.

However, while the NC20 have great noise canceling, they only have moderately OK sound

With the correct size silicone tip, these earbuds have a noise isolating effect that block out moderate background noise fairly well

After struggling with cheap o wired headphones for years, after my last pair bit the dust, I decided on these.

The sound quality is just ok and but not impressed ; also while on the call,the other party was getting a 2 s guitar like noise every time I finish my word
