Sennheiser CX300-B Earbuds (Black) Reviews

I'm genuinely shocked that folks are unimpressed with these buds. They've served me very well for a looooong time. Yes, they handle bass veery well, but I never found that was at the expense of treble, not at the start (are now, since 4 years of earwax... yeh, you knowaddamean). Could be better isolating? Sure, but I regularly hear nothing of the outside world when I have them plugged, unless someone's near me. I like being isolated, buuuut, I guess I like being able to hear when the truck is about to collect me or whatever.

What impressed me most about these, srsly, is the comfort. I have a laaarge collection of earphones that I've ditched because they lack a satisfying suction-cup attachment to my very (apparently) malformed ear canals. So many would just drop out of my ears so very easily. Until these.

Now, alright, they're probably long in the tooth now, and I'll prolly have to replace them b4 year's out, but for what its worth, I have yet to buy anything I was more satisfied with.

Like many other people, I got my cx300's as they were widely available on the high street with not much competition at the time. They are mostly known for their bass which is very abundant. The problem with that much emphasis on bass is the rest of the range suffers. Treble, in particular, suffers quite badly and is drowned out. Add to this very little clarity in the bass which doesn't have great extension anyway and for sound you are soon left wanting.

The trusty cx300's are quite comfortable to wear but isolation is not that good due to the shallow insertion and cable noise can be quite bad. You just get the feeling they were designed for a 13 year old who just thought more bass was better, people's ideas have moved on since then. Overall there are  much better for the price out there. Also there are many fakes out there which are worse but come without a warranty (which you may need).

These IEM's are very comfortable so they can be worn while lying down with no discomfort.

The bass is the best part of the CX300's, while the mids are average and the highs are lacking.

For the price, these are decent headphones and anyone interested in relaxed sounding headphones, this would be a nice purchase.

Well worthwhile upgrade and not too expensive. Emphasized lower end.

My only complaint after using these for the gym for over a year now is that the cord length is different from the split to the buds.(one more than twice as long as the other)

For a price this earphone has, it sounds great. A good bass response for something this small, and superb isolation from outside noise. Without music on, you can't barely hear anything else, as it doubles up as earplugs. But design wise, it should have a normal Y-shaped wire split to left and right earphones instead of going back 'round the neck. Just too messy. And the wire insulator material is to rubbery and grippy. But overall, the x-factor is the sound. But it could've been cheaper.

So, the other reviews are fairly accurate.  I bought (two pairs of them!) a while back and I thought they were good, Senheisser brand made me feel smart.  If only I had come here first (or known about head-fi) I could have made a better decision.  At $40 they're not worth it at all.  If you're willing to drop double that get the RE0s, they will not disappoint.

The bass is just bloated, but you feel like its warm and full until you hear a good set of cans (or even IEMs) and then you want to EQ it away, and can't.  Don't waste your money.

I should disclose that I purchased these headphones for $15, and for that price I recommend that anyone snatch them up as a back up, or workout phones. However, not sure that I would purchase them for $60 or even $40. These headphones really struggle with mids, and sometimes the bass is flat-out overpowering. I like to test out my headphones by listening to Pinback, as their music is a good representation of the aural spectrum. I found that the bass (which under normal circumstances should be almost an afterthought in a Pinback song; I have heard the drums in their songs described as "percussive breathing") took over the rest of the song.

Isolation on the CX300s is a mixed bag. I use these on my train commute and find them more than adequate to block out the train noise and other passengers; however, the cable noise is sometimes too much to bear.

Anyone looking for a quick and dirty upgrade over stock headphones should consider these, especially at the price I paid. If you are looking to spend 40 or more I would keep looking.

I read great reviews for these earphones but when I started testing them I felt cheated, the sound coming out from the earpieces was really tinny and a tad metallic, perhaps I didn't break them in but the small drive and lack of range was abysmal.

I cranked up the volume and fiddled with the eq trying to wring out some bass to no avail, then the cable noise set in and I was trying very hard not to move the cords while I was walking, the cable noise was so severe that I had issues listening to the music while walking.
