CX 300S Ear - Canal Headphone with Universal Smart Remote - White

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.

Bought these for my PS Portal, adequate sound, perfect job.

These wired ear buds give well rounded sound with a bit extra bass. A good seal in ear is easy to achieve with the selection of silicone cups that are in the box. As a result outside noise is interference is markedly reduced. Cable entanglement is not a concern due to the type of cable used. The in-cable switch start/stop and track advance works well. My only niggle is the 3.5 mm jack is in some cases a bit tight to plug in or remove. Overall a good product in my opinion.

Unfortunately they don't make Sennheisers Momentum 2 earphones anymore so replacing with these cheaper ones. Compared to mid or high range Sennheiser the bass is boomy and over emphasised but for casual listening it's a lot better than not having enough. Microphone works perfectly. Controls on the wire are limited to only play/pause rather than also volume control. Overall for the price these are a great buy. Just a shame they no longer offer a mid range for a more refined sound but as I said, the sound is at least full and satisfying to the casual listener.

I'm gonna have to find another brand than Sennheiser I like. Their products are just... now built to last. This is the third pair of CX-branded earbuds I've bought and none have lasted beyond two years. After a few months, the ends of cables turn to literal mush - apparently readily dissolving on light exposure to skin oils or body heat. A few months later, one of the earbuds will stop working and that'll be it. Unfortunately, this new design with titled earpieces is just both less comfortable and a worse fit. There are far more sharp uncomfortable edges in contact with my ear, and they pull out incredibly easily while also feeling like they're fitted in too deeply. Even a slight motion of the stiff cable will pull them loose, or they'll just pop out on their own while I'm completely stationary. The CX100 already had a stiffer cable than the pair before that and those I could tug on and not pull them loose, these however don't want to stay in even when jammed in uncomfortably. The larger earplug size is also just plain uncomfortable, while the default appears too small in comparison to the CX100's perfect fit. They're not interchangeable earplugs though, so I can't simply swap them over. Sound quality is fine, too bass heavy (I've no idea what the commenter complaining about there being too little is going on about), but that's something that I can adjust to and maybe something that'd lessen over time. But even having them a couple of days they're simply not comfortable, and I'm already aware they're not built to last. Even with an even thicker cable yet, I'm aware in a few months it'll turn soft and peel off, and then a few months later I'll lose sound on one side. That's just a constant of their construction quality. The thicker cable (and volume control) also doesn't let you loop it around your ear, which often helped with a secure fit or to get rid of cable noises. So that's off the table too. This is a real disappointment across the board. I already resent paying for a new pair every two years because of their material choice, but taking a product that fits perfectly and making it atrociously uncomfortable as well as just more expensive? It's just a regression.

The sound is excellent, you can buy better quality sound but it is at least £20 more expensive and will not be as rugged. I have been through loads of in ear headphones as I listen to audiobooks and music all day and they usually die due to being caught on something or having appallingly shoddy connections to the cables that fray. Whether expensive or cheap they have all failed in less than a year, Soundmagic, Betron twice, Sony, a pack of three cheapies and five Sennheiser until this pair of Sennheiser CX300S. Obviously quality has improved. If I was to niggle about something, the cable is a bit long but that will be a plus to some people

I bought these back in august as my previous earphones were beginning to cut out. I used these daily until today The quality both of the product itself and sound quality seemed great. far superior to the cheaper earphones I had been using prior to these. A week ago one of the two earphones began to cut out intermittently - I stopped using it as it became irritating to listen too. today I noticed the audio quality of the remaining earphone dramatically get worse. so I decided to check out what was going on the the earphones. After unplugging the earphones, the audio jack (male) snapped off into my audio jack (female) and I was left with damaged earphones and a broken audio jack (male) in my speakers! These have been used daily, but have not moved from the fixed position at my PC where I use them. It is pretty shameful they have lasted for less than 6 months.

Very comfortable, great sound clarity, would recommend.

Ich nutze diese Kopfhörer vorwiegend für mein Steam Deck und Meta Quest 3. Da Bluetooth Kopfhörer hier eine ziemliche Verzögerung haben, ist AUX immer noch das Beste. Ich nutzte vorher JBL On-Ear Kopfhörer, auch für ca.20€, die qualitativ zwar völlig in Ordnung sind, aber leider stören diese auch das VR Erlebnis weil sie mir der Brille kollidieren. Dann habe ich gute alte iPhone Kopfhörer per AUX verwendet, die haben die besseren Höhen als diese hier, aber fallen mir immer raus, das Hartplastik hält eben nicht gut. Und genau da setzen die Sennheiser an. Sie bieten erstens 4 verschiedene Größen der Stöpsel, mir hat die Standard-Variante die verbaut war schon sehr gut gepasst. Dazu dichten sie die Aussengeräusche sehr gut ab, wenn man die richtige Größe gewählt hat. Wie ein Ohropax eben. Der abgewinkelte Stecker ist auch sehr sinnvoll, gerade bei der VR-Brille. Gerade Stecker brechen gerne schnell ab, wenn mal was runter fällt. Der Beutel zum Aufbewahren ist auch super praktisch. Das fehlt bei vielen anderen Herstellern, und dann findet man die anderen Stöpsel nie mehr. Sound-technisch gefallen sie mir außerordentlich gut. Die Höhen sind zwar etwas flach, aber die Mitten und Bässe klingen sehr schön. Ich kann für den Preis von ca. 22€ also absolut nicht meckern.

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

Dont wait super quality and HI-RES Bass quality good

3.5mm jack wired headphones with Mic for mobile phones is more and more disappearing from the face of the globe and personally I do not like this idea at all, including that I do not want to even buy any mobile phone without 3.5mm jack option. Sennheiser CX300S are not very expensive headphones but there are still a quality headphones from this firm, and I buy there headphone products for two decades already, like this one Sennheiser CX300S mainstream headphones, to those Sennheiser headphones of much higher quality and much more expensive. I even bought this same Sennheiser CX300S headphone model one time in my life already, and I did not make mistake, because it is a good product. Yes, you cannot expect the "Start Trek" sound from them and for High Fidelity listeners, but they are not created for them in the first place, and for the others this headphones will be just fine, especially in this price ratio. All in all, I recommend them. Thank you.

Great headphones, withstood a lot of abuse before the mic and switches gave out. I often would accidentally yank the earbuds out of my ears (catching the cable on a door handle or whatever), but it took a couple of years before the inbuilt mic and switches stopped working. The cable is pretty tough. The headphones themselves still work fine and sound great after 3 years or so.
