The Sennheiser CX300-II Precision in-ear earphones extend upon the legacy of the highly successful original CX300 models by improving fit ergonomics and delivering slightly clearer overall sound. Comfortable, non-invasive ear canal fit affords mild isolation and an easy wearing experience even for in-ear newcomers. They're ideal earphones for remaining aware of your surroundings while listening -- provided you're not turned up too loud!

Applications:

The German headphone giant makes its powerful presence felt in the highly competitive 'under $50' in-ear category with the Sennheiser CX300-II Precision earphones. The CX300-II fit style could almost be considered a hybrid design somewhere between a shallow-fit earbud and the deeper insertion characteristics of a true in-ear monitor [IEM]. The CX300-II sound quality is certainly better than most earbuds but probably not quite up to par with significantly more costly in-ear headphones over $79, but their overall sound quality performance remains quite close at a friendlier price. The isolation factor certainly won't match that of an IEM either, but the CX300-II still provides decent external noise-blocking equal to many non-'noise-cancelling' sealed on-ear headphones. The mild isolation level is ideal for listeners intent on remaining aware of their surroundings.

The Sennheiser CX300-II Precision's mids & highs are clear-sounding, but not brightly extended in the uppermost highs which is smoothly rolled-off. The bass presence seems to be significantly affected by the user's choice of eartip and, of course, the overall tightness of the earpiece's fit within the ear canal; given the right tip fit, expect a punchy full-sounding bottom-end response. The CX300-II occupies a unique niche between earbud and in-ear headphones and is a very nice initial step especially well-suited for in-ear earphone newcomers wanting better headphones than the stock buds found with your portable player device.

 

The Sennheiser CX300-II Precision earphones come with black silicon eartip sleeves sized small/medium/large. Try them all and select for the best sound quality and most comfortable fit. The inconspicuous matte-black color scheme of the CX300 earpieces and cabling resists showing dirt and looks pretty slick to boot. Highly efficient operation and a low 16-ohm impedance rating ensures plenty of output from any mobile audio source like iPods, iPads, Kindle readers, MP3 / DVD players, laptops, and portable gamers. The asymmetrical "J" cable style minimizes cord slack on the move when hooked up to a portable device on your belt or armstrap. The 40" cable is terminated to a mini-plug 1/8" (3.5mm) termination. A strong 2-year product warranty remains standard on all Sennheiser products.

Guys the asymmetrical cable is actually a good feature.
Posted by AceStar from Australia on 2014-01-27

Recommend Product: Yes
Pros: comfort, decent sound
Cons: high frequencies a bit harsh, cord tangles easily

Do the people complaining about the asymmetrical cable not know what it's for? The cable that goes between the two earpieces goes behind your head. This gives three benefits. Firstly, you can take the earphones out of your ears and they won't fall to the ground, they'll dangle around your neck. That's why some people call this a "necklace style" cord. Secondly, the fact that the cable rests on your shoulders helps get the cable out of the way (eg when eating) and stops the weight of the cable pulling the earphones out of your ears. Thirdly, it helps reduce that transmitted cable noise (which some people call microphonics) because the cable is resting on your shoulders. This helps prevent the noise transmitted to your ear when anything rubs or knocks against the part of the cable below your shoulders.

There is pretty much no downside to this setup except that it doesn't really work well with headphones that have an integrated mic because the mic wouldnt be near your mouth, given the cable goes over your shoulder and behind the neck.

That said, I should comment on the sound. If you use the smallest buds they stay in the ear well and are pretty much proper iems. I never could get them to stay in my ears well with the medium buds.

The sound quality is good, if a bit harsh in the high end with some resonant frequencies. The bass is not too heavy for iems and the midrange is great.

The claim to fame of these is that they are great quality given the low price. Unfortunately in Australia this falls apart because they are around $80 here, making them less value for money.

I would still recommend them as they are my most used headphones, and I wanted to get across how convenient the asymmetrical cord is.

Great sound but faulty design
Posted by MoshPitVeteran from Vancouver, BC on 2011-09-03

Recommend Product: Yes
Pros: Focused clear audio, comfy, good noise cancelling
Cons: Faulty wire system

I have been through over a dozen pairs of headphones. ipod, sony, jvc, skullcandy. And these are the best sounding, most reliable headphones that ive bought. However the wiresystem is flawed in that there is no anchoring system in place to prevent pulling and/or breakage. The sound is great though. The bass very good, but focused so the midrange, treble and vocals
are still audible. Most earphones like these made by the above companies only last (on average) about 3-4 months. The pair of sennheiser's i have worked for just over a year before the left earphone stopped working a few days ago. they're built well but the wires always get pulled over time which eventually cuts the audio in one of the speakers. I would like to see some sort of tie-in system that securely anchors the wire into the earphones and the plug. Maybe with thicker wires? Also the earphone-only model was recently discontinued in favor of a pair with an attached ipod microphone, which isn't practical or necessary if use them for an ipod. If you do buy these earphones, i suggest an extended warranty if possible. Otherwise you can return them every 30 days to gaurantee your headphones will always work, which might not be a bad idea.

Okay sound for the price. You could do better, however.
Posted by Mishalex from New York, NY on 2011-08-24

Recommend Product: No
Pros: Good bass sound
Cons: Bad electrical insulation, poor construction.

I found these headphones to be pretty decent on the whole as far as overall sound quality without the need to crank up the volume too high. The isolation and bass were very good for the price in my opinion. On the other hand, vocal treble tones sometimes have a slightly washed out feel to them, Also, I've always found earbuds to be uncomfortable, and these are no exception. The assymetrical design means that one of the two buds will constantly fall out of your ear.

The main problem with these earbuds is that (like most earbuds) they really aren't very well constructed. The wire is far too thin (poorly insulated), and hence has a tendecy to pull and damage easily. It got to the point where I couldn't listen to these headphones while folding laundry, because the wires were so poorly insulated that the static electricity actually traveled through the wire to my ear. Ouch!
