Great sound, when it works

These had great sound when they worked, but only two weeks in one earbud started to fade in and out. I returned them and got a cheap set of Sony earbuds.

  • from Toronto, ON

Great sound, but fragile

If you can't hear the bass, or if you can't achieve any noise isolation, then try switching out to larger ear buds, and playing around with how you place these in your ear canal to achieve proper seal. These headphones have a great, clear, balanced sound with good bass, but it's sometimes hard to achieve it because the silicone inserts are soft, and don't push very hard against your ear canal. It seems like Sennheiser was trying to push the limit on how light and how small they could make earbuds, and they nailed it, but at the price of durability. These things are so tiny, most people will be able to wear them and put their ear on a pillow comfortably. They won't last very long if you use them while working out or running. They are best suited for office work, commute, and other low impact activities.

Nice and balanced sound

These earbuds have nice and balanced sound. This is good for listening to music that does not have a lot of bass, however, if you are a "basshead" like I am, these earbuds do not exaggerate on bass. If you do want to get the most low end sound out of these earbuds, I recommend listening to bass boosted music or you can try to bass boost the music yourself using audacity. Or you can just download an EQ app. The noise cancellation feature is a great plus, they have a nice and comfortable fit.

These earphones are way too fragile and vulnerable to any sort of damage. I used them for about a year and they completely died. If you buy these earphones, don't ever try to bend or tie it into a rope because that will easily destroy it. I used a lot of different earphones from Samsung, Sony, and Apply and they still are fine even though I wrapped it into a loop to put in my pocket. They need to make these earphones more durable and stronger to hold physical exertion.

  • from Brisbane


Low end is non existant. No punchy bass as advertised. Waste of money. Fail!

  • from Mississauga

Good. But not worth the price.

These headphones are pretty good. Theyre not the most comfortable pair of headphones, long usages can make this uncomfortable to wear.Doesnt do much noise isolating. Decent bass, good clear audio. The price should be lower. Buy it on sale.

  • from Victoria, BC

Great sound, but very bad noise isolationw

Great pair of earbuds overall but for sound isolating earbuds they didn't quite live up to expectations. On the box it says "noise cancelling" not "sound isolating".

  • from Toronto, ON


save your money. These are much less quality than the slightly more expensive variety. Sad I cheaped out. Not good at canceling sound. Poor sound.

  • from Baku

not great quality

not perfect quality!! sound is like as an ordinary not expensive any earphones

  • from Kelowna, BC

No complaints here

Just purchased these today and they sound amazing!! I had another set of JVC that were same price point and these blow them out of the water. Great ambient noise reducing and great treble and bass. Buy them if you're looking at them!

  • from Vancouver, BC

Poor build quality & disappointing bass

Having previously owned the CX175 & CX200, I was expecting similar performance from these headphones. Not the case. Treble and midrange audio quality is quite clear, but the low end is virtually non existent. Build feels cheap and flimsay. I use these when running, and within 1 week the right earbud cut out (likely due to a little moisture from sweat) and a week later the left cut out. Never had this issue with other Sennheiser headphones. And thanks to BestBuys no returns policy for earphones, I'm stuck with these useless things. Best avoided.

  • from Montréal, QC

Great choice

Good value for money. High quality sound

  • from Vancouver

You can trust 100% German quality

Absolutely meets my expectations, the 'I' shape connector is an asset. Mark right and left bud simply with a tiny fancy nail stickers of the different colours to be able to put them correctly into your ears fast..)))

  • from Victoria, BC

Quality Headphones

Bought these for my son's birthday, and he loves them. The sound cancelling feature is an added bonus.

  • from Scarborough, ON

Excellent Performance

The earphones come with 4 choices of noise isolating buds, all of which are very comfortable and efficient at outside noise cancelling. the ear buds fit quite nicely into the ear canals and provide great quality sound. the bass is quite satisfying too. at this price this is certainly a bargain.
