    Got these a replacement to the CX300 mk1s which I have been using every day as I walk to an from work.

    First thing to note is the build quality. A bigger, gold plated jack looks and feels alot sturdier. Its bigger size has however not been a hinderance. The junction reinforcement, where each cable splits off has also been beefed up making these feel much more resilient. Not much has visually changed with the driver unit, it has now got a sloped back but overall looks to be the same size etc.

    The biggest difference comes in the sound department (where it matters!). The bass response is much better and is pretty astounding for in-ear headphones at this price. I quite like walking along to the odd dance track and tunes like Mylo - Destroy Rock 'n' Roll (Tom Neville Clean remix) sound excellent. The bass has plenty of weight and presence and the high end is tight & crisp.

    I'm not going to comment on how well these head phones fit as that is a completely personal interaction, they either will or they wont. There are three different sized rubber ear pieces included, so hopefully one pair will work. There is also a soft sprung clasp pouch included, for stowing the headphones when no in use. This is a welcome extra but I've reverted back to my usual hard shelled tin as it offers a bit more protection whilst bouncing round my bag.

    To summarise, if you already own CX300s, the mark twos are a worthwhile upgrade. If you are in the market for in-ear headphones, these should not be overlooked. Top Quality Sound and Build for next to nothing.

    **** ONE YEAR EDIT ****

    Well after a year of daily use (hour walk to and from work) a connection in the left ear has gone. Resulting in only faintly audible levels coming from the left hand side. There's a two year warranty so it should be covered.

    Alas, I am no longer at the mercy of rubbish, overpriced Apple earphones.

    I was once happy to call myself a proud owner of Sennheiser earphones. I used them everyday, starting from the moment I'd leave the house, and couldn't be more pleased with the quality of sound delivered. On one fateful day, over 2 years after they were purchased, they were snagged by a hook on the train, which rendered them useless and left me feeling utterly desolated.

    Having bought an iPhone 5, the newest, coolest phone on the block at the time, I was sure their redesigned earphones would do the trick. Ah, if only that were the case. They work alright when I'm at home in utter silence, but if I dare attempt to use them in a noisy environment, I hear nothing but faint voices and murmurs in the background. Maybe it's my brain telling me it's time to get some Sennheisers.

    I am pleased to have succumbed to this temptation. I bought these only 2 days ago but I have not enjoyed my music this much in a long time. The sound is crisp, the bass is thick and distinguished, the voices sound natural and clear. You know that loud, annoying group of friends chatting hysterically when you just want to listen to your damn music? You can forget about them. And the wailing baby. And the vigorous roar of the bus engine. The Sennheisers will clog your ear up, and you won't hear squat from the world around you unless it damn pleases you.

    All in all, 5 stars. Does exactly what I want it to and no more.

    I had been using a pair of on-ear Sennheiser headphones and bought these as an upgrade and wanted to see what ear-canal phones were like. The sound is very good, full, balanced and involving, with effective bass response without being in any way overbearing. Turn them up and the sound just grows rather than gets louder, with no harshness. The noise isolating aspect let's you enjoy the music with no outside distractions.

    Once you fit them properly in your ear, they are comfortable and can be worn for long periods of time without any discomfort. Fantastic value for money.

    Do you want to listen to music without other people hearing it? Do you like black things with little shiny silver bits on them? Then these might just be for you!

    Features include:
    - decent sound quality, as far as I can tell. But I'm just some pleb listening to 256kbps MP3s, not George Martin with a DAT machine.
    - pretty good bottom end, if you like that sort of thing. If you don't like that sort of thing, change the EQ setting and I'm sure you'll be fine; otherwise it's a bit like sticking your pinky finger too far into your earhole.
    - reasonably durable. I've had them a couple of weeks and they haven't broken yet.
    - fairly comfortable, insofar as sticking foreign objects into your ear ever can be.
    - sensibly priced. But if you want to spend £200 on a pair of headphones, that's your call. Look elsewhere.
    - okay accessories. Comes with extra rubber ear-plug bits that double as fake beauty spots and a spring-clasped carrying case. The latter can be clipped onto your nose if you want to pretend to be a koala.

    There is some cable noise, which I know aggravates some people. You can ameliorate this by sticking the cable inside your shirt, which tickles pleasantly, or you can embrace it and adjust your stride to sync with the music, adding an extra layer of percussion. If it's a big deal, spring for wireless headphones and accept that you're going to look like Lando Calrissian's factotum in 'The Empire Strikes Back'.

    In short, I like them as much as, if not more than, other earphones I've tried.
