CX 300S RED In-Ear Earphones, Red

Note 1: This is only the 2nd pair of ear-canal headphones I have used. Note 2: I have bought these for music listening purposes only. Pros: They are lightweight, comfortable and come very well packed. They have good length of cord and provide very good sound from: cassette player, Android Phone and mp3 player (Boom!). Was very impressed. There are numerous ear tips supplied but I found Aiivioll Silicone Ear Tips give more bass and fitted my ears better. I found also that you do not need high volume as they have high sensitivity. This means the battery driven or rechargeable devices should be able to play for longer. Cons. Wire noise can be experienced when cable banged/tapped due to high sensitivity.

I think these sound fantastic good bass, good noise cancelling and a comfy fit.

Good Headphones.

Excellent earphones. I've had Bowers & Wilkins earphones in the past and I must say Sennheiser's top them. My first ever pair of Sennheiser's was over a decade ago when I got the CX300's. The CX300S is newer, has a modern design and a button to pause tracks, also a mic for calls. I am very happy with my purchase. For less than £20 you will not find better earphones. Trust me on this one I know what I'm talking about!!

I normally go for CX300 II or CX400 II ear buds, but decided to try these as they were cheaper and could be supplied by Amazon (and thus left in safe place if not in). Soundwise, compared to the aforementioned buds—which I find to be nicely flat across the frequency range except for a bloated bass (just what I need when walking alongside noisy traffic!)—these are definitely more middley and less neutral. I will use them for music only as a last resort, but they're acceptable for listening to speech podcasts, which is my preference when walking to and from work. Feel-wise, they're quite heavy—not really a desirable quality in an earbud—so are liable to getting pulled loose from the ear and requiring pressing in from time to time. Otherwise, they're comfortable in the ear. Build-wise, they feel quite solid and less fragile than the CX300 II and the CX400 II. The cables of the CX300S are certainly thicker. The downside of this is the added weight. As with similar items they are supplied with a choice of different sized buds (medium is right for me). However, there is no supplied shirt clip; a clip is especially important for these relatively heavy ear pieces. Happily I have a few spares. They're not awful buds (I've had worse) but I won't buy more again once they break—they're too flawed all round.

Got those as I wanted a simple headset, wired with a mic, in replacement of my beloved lost Momentum In-Ear (wired version, which is not sold anymore). I love Sennheiser sound signature, so those seemed to be the best option around. But they're clearly not. They sound almost like a cheap free pair of earphone that would be offered along side a smartphone. As a result, I'm barely using them. For some calls maybe, when I can be bothered to take them out. I'm not enjoying listening to any music on those. An oddity in my history of buying Sennheiser. Comfort is good, nothing to tell around this. Build quality: well the core of it might be sturdy, but the little plates (where the Sennheiser logo is engraved on the earpiece outer side) just fell off (unglued itself), on both side, after a few weeks. It really displays the cheapness of it. I know they're not the same range as the Momentum, but for the price I had way better experience with Sony products in the past. A shame.

Very comfortable, great sound clarity, would recommend.

These are great and very reasonably priced

uzun yıllardır kullandığım bir kulaklık. halen daha kullanmaya devam ediyorum.

Excellent quality and product. It comes with a nice little pouch to carry it in. Good noise cancellation as well.

Great fit and sound

Dont wait super quality and HI-RES Bass quality good

Despite my research on the best wired-in headphones with external microphone, which shows these as the TOP HEADPHONES, the sound quality is far FAR below what I am used to with my current Bose. I would NOT recommend these.
