The rumors are true


Seeing all of the 'these will fail' reviews, I ignored these warnings and went ahead to purchase the most comfortable earbuds I have ever owned. Then, after about 8 months, the right speaker died. I've come to accept this from most earbuds, but I was...

Excellent sound quality, comfortable

Not built to last

Decent for the price, amazing when on sale.


The first time I bought these was actually at a used record/video store. They were marked for clearance for about $15. I was a little leery of in-ear buds, but I thought the price was decent. I was absolutely blown away by how good these sounded....

Not a huge con, but I would really suggest that once you figure out the size of the rubber tips your ears take, order some more. I've found that the tips have a tendency to wander. Fortunately, I've almost always found the missing tips in my pockets or...

Good headphones


I would recommend this to anyone looking for a decent pair of headphones.

Much better than headphones that come with brand name phones. Even the Apple branded ones ; It doesn't fall out as much and the bass and mids sound fuller and clearer. Actually using these as in ear monitors. They block out almost all the sound and...

Did not come with a nice case, but I guess you need to spend more for that

I think I've always been used to my headphones being a tad on the "muddy" side when they've had killer bass. Never have I used IEMs that have this much low-end though. I've since bought several pairs to compare with, and have come back to these as my...

Amazing lows (bass, sub-bass) ; Decent mids ; Decent highs

A tad on the "muddy" side

Great earbuds


Depending on your taste of sound, these have pretty good bass, which may or may not be for everyone's taste. It does have a 90 degree connector on the end, which again, may or may not be for everyone.

Lasted over a year (Originally purchased in 11/24/2012 ; Good sound isolation ; At the price I got them for ($19.99), these are a great value

You kind of are unable to use them if you lose the ear tip pieces

Nice little earbuds


I've had more than my fair share of disappointments when it comes to earbuds, and these have yet to disappoint. Even being an audiophile I've purchased 2 of these (because eventually I will manage to break these)

Since I was first exposed to Sennheiser I've been impressed with their quality, and these earbuds are no different. For being as small as they are they have taken a fair amount of abuse from me and seem to be holding up well. That's saying something...

I'll note upfront that I'm a bit of an audiophile so this may not be a con for everyone, but it is for me. The sound reproduction is decidedly inferior to my old CX485s (I really miss them). These fail to reproduce the same level of richness/fullness,...

Not so good


Were nice while they worked

One earphone went dead after 1 month use. Not too happy

Consumer review by:

Great for Sale Price


Great for the sale price of $15. 50x better than the default iPhone headphones.

Great sound, noticeable bass. Fit snugly in your ear, and have three different sizes if the defaults don't work. Will not fall out while exercising

Cable is loud, and you can hear it at medium-level volumes. Turning it up solves this issue, but is undesirable ; The rubbery texture of the cord also makes it a bit hard to untangle

Sennheiser CX150


Overall, it's pretty good for the money.

Sounds decent for the money. The item was purchased on sale

Price dropped after purchase. The cords will catch on anything and everything

Consumer review by:

Nice headphones


Fits nicely ; Always have issue with earbuds staying in. This one works

None really othre than there is no control for telephone call like most other headphones. A pain if you use this on android/iphone and someone calls you
