Sennhesier CX300II Precision Series Noise Isolating Earbud Headphones - Precision Black

This earpods are awesome, excellent noise canceling, use it to monitoring the sound of the camera in video shootings. Great sound, fits perfect and they are Sennheiser.

This is a great product.

Great headphones love the sound quality. Very nice overall. Would buy again. Edit: 2.5 years later and I'm still using them. They have gotten heavy usage. 10+ hours a day for about 7 months straight at one point.

Not as good as I would have expected, and I've had Sennheiser ear buds before. Sigh.

Excellent sound and good isolating properties

excellent head phones for the price

Excellents écouteurs.

iphone4(iPod)用に購入しましたが，相性(音域バランス)が今一でした。 皆さんが言われるような低音域は全然感じませんでした。イコライザ機能で調整しても主に(中音域〜高音域)シャカシャカ音(強調されるのみ)しか聞こえません。 個人の感想ですが，iphone付属の安物イヤホンの方がマッチングは良いです。

It's been a worry few months due to neighbours music going off throughout night. I already owned a well known brand of NC headphones but sound would still come through. I was undecided whether in ear headphones would help, after far too many sleep less nights I gave in. These in ear headphones have saved me and I wish I had purchased sooner. They sound amazing, much clearer than the NC headphones I use which sell for a lot more. They're not so good for calls as being in ear you'll hear your own voice loudly, but for wearing during the day to listen to music they block out incoming sound so you can focus on what you're doing which has been a struggle. A really great buy, only issue I have is the length of cable between headphones, it is short on the right side... That would be only issue I find.

Tout est dans le titre. Qualité d'écoute énorme (sur threatened de MJ que je connaissais depuis un moment j'ai découvert une respiration qui marque le rythme!!!) Isolation du bruit extérieur totale (sans musique dans un openspace je n'entends quasiment plus les collègues!!!) Coté confort je n'ai jamais aucune gêne à l'oreille (ce qui n'est vraiment le cas avec d'autres écouteurs) Coté sport je cours avec (ils restent en place sans aucun problème)et ce depuis plus de 2 ans sans aucune détérioration Le seul hic c'est que je désespère de trouver une équivalence dans les kit piétons (je cherche encore)

I got these earbuds as a replacement for a pair of CX 300-II earbuds I bought back in 2010. These used to have a neutral, flat frequency response, but now it sounds like there is a peak at 5550 Hz. Feels like the earbuds are "whistling". If I aply a -9 dB dip at 5550 Hz with EQ, their sound is neutral. I tried adjusting the earbud position in my ears but no avail. I compared these to a cheaper pair of CX 100 earbuds, and it's odd how they don't have this peaking frequency and in fact sound more neutral than the CX 300-II. I'm considering returning these.
