The earphones are labelled as Sennheiser CX 1.00, Sennheiser CX 2.00i, Sennheiser CX 3.00 and goes right up to Sennheiser CX 5.00G. The CX 3.00 and the CX 5.00 come with an in line microphone, while the others come without it. According to Sennheiser, the new CX series headphones are built to offer more comfort and better sound quality with improved driver design. For this article, we will be reviewing the CX 5.00G version. Update: For the newest release in the CX series, check out the Sennheiser CX 7.00 review.

Build Quality

The first thing to notice is that Sennheiser has created these headphones to have a different design. For some years, Sennheiser has been producing similar looking bunch of earphones and that has not been popular among the more fashion concious consumers. Even if they did produce excellent sound quality, Sennys lagged behind when it came to looks. But that is not the case any more. The new CX series comes with vibrant colours and a different appearance that will easily catch an eye. The earphones are brushed metal finish which makes them feel very strong and sturdy. They are connected with a mostly flat elliptical shaped cable which will not tangle when you put the earphones away. The earphones are connected with a slightly elongated metallic strip as seen in the photograph below.

On the left, we have the CX 3.00 with a more compact form factor and on the right we have our CX 5.00 with a more elongated back. Personally, I would prefer to have a compact version, but the elongated body just gives more support to the cable and ensures that it will last longer.

The inline controls have good quality tactile switches to do basic functions such as answering the call and stuff like that. Most cheap headphones out there come with a bad quality in-line control enclosure which can just break apart with a little pressure, but Sennheiser has made it very compact and rugged by sealing the enclosure tightly. I doubt it would break so easily…and if it does, you have the advantage of 2 years Warranty.

One good thing about Sennheiser warranty procedure is, they simply don’t ask questions. They just replace it with a new one. It applies to all of their products under warranty.

Additionally, you also get a carry case for storing your precious buds and 3 pairs of different size earphone tips for obvious purpose. Sennheiser has also made available 3 different colours for the CX 5.00, namely Black and white. The Black has a shiny metallic silver backplate, while the White has copper coloured ear phones. Personally, I prefer the black version because it looks more sexy.

Sound Quality and comfort

The sound quality of the Sennheiser CX 5.00G can be compared with the Momentum series we reviewed some time ago. You can expect to hear perfectly flat sound from the CX 5.00. By this, I mean that the drivers have nearly flat response and do not boost any frequency. So, you will be hearing your music the way it was recorded in the studio.

With 118db SPL (sound pressure level) you can drive the buds way up on volume, but I would recommend you to not do so if you care about your ears. The drivers have 18 Ohms nominal impedance at 1kHz, which is slightly higher than average, although you can sometimes find earphones with impedance going up to 32 Ohms. We usually see high impedance drivers on on-ear or over-ear headphones, not on the tiny in-ears.

For better response on the lower-bass and the upper highs, the 3dB frequency response of the drivers starts at 16Hz and ends at 22kHz. This allows a perfectly flat, unattenuated response across the entire audio band which could have been affected due to the roll-off of the response curve if the 3dB starting point was 20Hz or the 3dB stop frequency was kept at 20kHz. In short, the CX 5.00 has the ability to produce tight and punchy bass, it just does not artificially emphasize any bass.

Because the design of the earphone is vented, you will not be having complete isolation from surrounding noise. The vented design is for the purpose of achieving better response from the drivers. If you are okay with having some external noise reaching your ears, then you should definitely buy the CX 5.00, or else go for some other design such as the Momentum.

The Sennheiser CX 5.00 is super comfortable and very light weight. The ear phones do not put any pressure on your ear canals and fit very snugly, neither is there any feeling of “weight” when you plug them in your ears. That way, you can listen to music throughout your entire commute or whatever you are doing.

The difference between the CX 5.00G and CX5.00i

When you hop on to the official Sennheiser website you will come across the two versions of CX 5.00. The “i” stands for iOS version which will work with all Apple products, where as the G stands for Android and Windows phone version. You can use the G with virtually all sorts of devices. There is really no difference in audio performance between the two versions.

I think Sennheiser has winner here! The sound is so crisp and clear, really amazing I ended up keeping these because they have more of a flat clearer sound while the Momemtum are a bit more bassy much better than beats for rock and metal

    Volume control

    For £50 they are amazing. Got them to replace Sony 650 in ears which after a year just didn’t sound nice anymore. These have very pleasant non tiring sound. I listen mostly to house music and bass is great while still having clear miss and highs. I’m no sound expert but I have tried various headphones, Beats, Sony, Bower Wilkins and other expensive sets. These sound about the same as Sennheiser Momentum On-ear headphones.

  3. Positives: NoneNegatives: Average sound. No Bass. Remote control not working (mostly) on my android phone - next tack, previous track, pause nothing is working!

    This may be the newer design from Sennheiser but the sound quality is not even as good as the older models like the CX 400 II. Everyone are boasting how good the sound is & how wonderful the bass is but I call them BS (get your ears checked by the doctor please!). Bass? What bass?

    The remote control does not even work on my android phone. When playing music, I can’t even get it to go to next track, go to previous track or pause nor increase or decrease volume. Whenever I hold down the button(s), all I get is the f***ing OK Google screen popping up – so freaking annoying!

    This is really a piece of junk charged at a premium price. A RIP-OFF!

  4. Positives: - Sound
    - Both Android and Apple supported
    Negatives: - The cable
    - The longevity of the audio drivers (deal-breaking)

    46

    I have just come here to write about my experience.
    I’m now on the third pair of these earbuds, and throughout all three the same consistent deal-breaking problems occurred.
    First off, not nearly as deal-breaking as the 2nd, is that the rubber, of the cable, encasing the wires of the headset them-self with time consistently becomes deformed to such an extent that it looks sick.
    As if you had dipped the cable in some kind of an acid and then left it to be dissolved, but pulled it out prior to the process being nearly complete.
    First time around, I was like, what the hell is this.
    Didn’t know how, but I had believed that it was my fault somehow.

    Now comes the 2nd, 100% deal-breaking issue.

    The sound pressure that the drives are capable of deteriorates with time.
    I had bought these earbuds finally expecting them to not be of the sort of which one or the other side stops working on me after a while.
    This didn’t happen, something even worse did.
    The sound quality deteriorates.
    It made me constantly feel as if one(all 3 times thus far it has been the right one) earbud was not neatly placed withing my earlobe, as if there was(and currently yet again, is) noise pollution coming from outside.
    The first time around, I didn’t sent them in immediately, still not having had been aware of that being an issue for which I am not to blame, but I had sent the set in for warranty service only after the right piece completely failed(stopped working).

    The 2nd time the same things happened.
    The cable wrinkled like a face of an old lady from Iran and broke all over the place, leaving the wires expose. This time I knew it’s a design flaw as I had taken care of storing the earbuds properly without a single exception.
    That didn’t make me send them in for service, but the right earbud again started losing sound pressure capabilities, making me feel as if always ever so slightly I have not fitted the right earbud properly withing my earlobe.

    I have “perfect” hearing, I was appointed the violin at the start of my music school by the professors because of my perfect hearing, and all throughout my life my hearing had in no way ever failed me.
    Finally I started to rely on that and have thus sent them in for service.
    Got a new pair.

    Now, another 6 months later, again the same friggin story.
    The cable has long since wrinkled and again it looks horrible, as if it’s some cheap Chinese earbud set, and the right earbud has as again lost it’s native sound pressure capabilities.

    I hope I’m going to be able to get a refund, as in the past, in a similar case with a Marley earbuds set, a reoccurring problem(one earbud failing on me), I got a refund after I had gone through 3 pairs of them.

    The worst thing about the CX 5.00 is that they don’t fail straight-out, but that they make you doubt yourself and that in my case resulted in disturbance and stress (and of course a lot of time lost not having a pair of earbuds all the while they were in for warranty service).
