Do not work with Apple Ipad Mini

The sound is fine (tried with an iphone), but they do not work with an ipad mini.

i've had these heaphones for 3 years, still work great

The secret is not to wrap/coil your headphones, just toss them in your bag/pocket loose and they'll last you forever. It's annoying to have to untangle them but it's worth it in the long run. sound is great and they have been going strong for over 3 years.

Good earphones for the price

I'm just about to buy my 3rd pair, I've found that each pair lasts roughly a year before one side loses sound and then the other loses it a week later. Keep in mind I usually store them with me everywhere I go, so that includes in my coat pockets in the wintertime and I even wear them when it's snowing/raining lightly outside. So even with being exposed to the outside weather, it still has a good life of around a year. As with any earphones, just try not to pull on them too hard. I cringe everytime something accidentally caught my earphones and pulled it out of my ears. Good sound and good durability considering how cheap these earphones were.

One headphone will fail

These are cheap and work really well. However, they only last for about a couple weeks, then one of the headphones starts getting quieter and quieter. Eventually, one headphone completely loses its ability to emit sound. I'm not an expert, but I think headphones main function is to produce sound, so these headphones are fundamentally flawed. I've owned 3-4 sets of these headphones and it's the same problem every time. If you need headphones for a weekend or two, these are great value!!

One week , one bud

I had these headphones for only one week and one of the buds already stopped working. I am not rough on my headphones at all so I am not sure how this happened. This has never happened with any other pair of headphones I own.

  • from Montreal, QC


Disapointing because they are very comfortable, sound amazing, but the left bud just stopped working out of nowhere. Read through the other reviews and found that this has happened to other users, and it seems to always be the left bud... not sure why.

  • from Vancouver

Quality went down

I've been going through Sony's entry priced ear buds like these for years, they've always been amazing but this version was a letdown. For the price it's still worth it because of the comfort and style but compared to predeceding models it's the worst pair I've had in terms of sound quality. Whereas the older models have more of a bass-y, surround sound environment, this one sounds one-dimensional, jarring and comparable to cheaper no-name brands. May go back to skullcandy or wait for the next iteration.

  • from Ottawa, ON

My second pair

This is the second pair of these buds I've owned. The left bud shorted out in the first pair after only a few months. The price is still hard to complain about, so I've given the product another shot. So far so good after about a month.

  • from Milton, ON

good until not so good

I got these about a week ago and they were pretty great for the price. Although not so sound isolating as it claims. The alternate buds fit quite comfortably. The left side stopped working suddenly , from no fault of my own.

  • from Ottawa, ON

Good value

While the sound certainly isn't amazing, it's hard to complain given the price and the physical comfort of the product. These are a good choice if you're on a budget.

  • from Regina, SK

Great headphones and great price

I needed new pair of earphones and on a budget so i saw this and bought it . When i tried it out i was surprised that the sound was crisp and the bass was great . I would really recommend this if you are in a budget

  • from Toronto, ON

Great value headphones

These headphones have great sound and noise isolating capabilities especially considering the great price. They seem to go on sale quite often but even at full price they are a steal.

  • from Saskatoon, SK


In generally, it is a good earphone with the price.
