A lack of inline controls and microphone might put off smartphone users, but audiophiles who place audio quality above everything else will have plenty to enjoy here. E.M when I demonstrate headphones so I’m going to stick them on and see how the CX300S match up against the competition. They listen to nine recordings for each pair of headphones, which cover a wide range of music and radio genres, giving a rating per recording and an overall verdict (not an average). gave these Sennheiser earphones a 5-star review, remarking on their superior sound clarity, texture and detail, while also rating the comfortable design highly.

Sennheiser CX 300-II review | What Hi-Fi?

The CX 300-IIs are a dramatic improvement over standard-issue buds, producing advanced levels of detail across the board. Of course, the debate over whether a straight or angled plug is better rages on, and we aren’t going to get involved. If you're looking for an affordable, decent-sounding pair of earbuds, start with the Sennheiser CX 300. Everything from the casing to the tangle-free cable (which includes an in-line mic and remote), makes me think these are going to shine. However, they’re very bass-heavy, so only really for casual listening unless you’re seriously into low frequencies.

This can be avoided by having a longer earpiece that gives more room for the tip to reach into your ear without the cable fouling against your earlobe, but a much easier solution is to angle the earpiece to more accurately match the angle of the canal itself, as done here. I found with audio things take awhile to break in (burn in) some people dont believe in it but from my experience in each component and speakers i have bought things have improved with burn in. If your ears are particularly deep, you may still find the cable fouls against your ear before you can get a good seal, but you can get round this by looping the cable over your ear and inverting the earpiece.

A good seal also means you can get a good bass response, and with Sennheiser having upped the bass level on the CX 3. I found the sound stage to be much smaller, and at times, having to crank the volume to get the highs to where I want them. However, despite everything now becoming wireless, you’d be surprised how popular the trusty wired headphone is.Before the older model i found a little harsh on highs and boomier bass and the new model fills out the mids a little more too. Editorial independence means being able to give an unbiased verdict about a product or company, with the avoidance of conflicts of interest. An impressive update on their predecessor, the Sennheiser CX 300 IIs boast full bass stereo sound and minimised levels of distortion to provide rich audio across the entire sound profile. The crispness of each note is sometimes lost in Rachmaninov’s Prélude, as it is with some of the synthesised noises and samples that make up Atoms For Peace’s complex percussion. I found the old cx-300 a bit bright and harsh these ones i can actually relax more too- it has more warmth but still with detail.

Unfortunately, the CX 300 II Precision earphones don't offer anything in the way of inline controls or a built-in mic, which might disappoint those looking for something that'll work with their smartphones or provide VoIP applications.Sure these are some well made durable in-earphones, but as stated before they don't look great, and they don't come with any travel bag or anything.
