Sennheiser CX 300 II Precision Noise Isolating Ear-canal Phones, Black

Product Information

When running the Sennheiser CX 300-II through our extreme basshead tests, they handled up to 47% of the maximum power coming from a Fiio E12 Mont Blanc amplifier while turning it’s bass boost on, high gain and applying a custom basshead EQ. The results were an outstanding increment of their mid-bass punch and sub-bass depth and reaching a very worthy basshead rumble and impact above the KZ ATE , Xiaomi Mi Pro HD , Panasonic RP-TCM 125 but still below the Sony MDR-XB50 , Sony MDR-EX650 , Pioneer SE-CX8 , KZ ZST , Xiaomi Mi In-Ear Headphones Pro or the Sony MDR-7550 / Sony MDR-EX800st . The earphones themselves feel lightweight but solid, with an air of durability that reminds me of the long-reigning Sennheiser HD1 In-ear. Cabling comes in the form of a no-tangle, elliptical design, replete with an in-line mic and remote. The whole affair measures a standard 4 ft (1.2 m) and terminates in a right-angled 3.5 mm plug. Call quality remains succinct and accurate enough, with my voice registering clear and crisp. Specifications Sennheiser Momentum – which can be bought as an over-ear headphones, on-ear headphone or in-ear headphone (can also be found in their Bluetooth variants) Applying an EQ, lower vocals clear up and mid-bass bleed is reduced but if the overall EQ is overdone their vocals can risk to get a bit ecoish (if done correctly there will not be any issues). Higher mids can get a bit harshy if pushed too much.

These are better than others I have tried that cost much more than these, eg SoundMAGIC E10 and Beats. The CX 300-IIs had a good frequency response – it wans't amazing, but it was solidly above average. They had good bass, which is something all good in-ears have to struggle for (bass requires moving a lot of air around, so the smaller the ear bud, the harder this is to do). The curve drops off a bit towards the mid-section, at which point the curve becomes slightly erratic, but manages to stay within the lines. After that the curve drops off a bit. Typically frequencies above 10,000 are used to add 'brilliance,' 'luster,' and a handful of other rather intangible qualities to sound. If you notice the loss at all, it'll likely manifest itself as softer vocal sibilance. The SE420s have a somewhat weaker bass, but have a much more even kiel to their response curve. The SE420s also have a weaker high end. The winner here will be decided by personal preference. DistortionThe Sennheiser CX 300-II are a very popular budget model from Sennheiser that has an incredibly small size and that Sennheiser markets as an earbud with “powerful”“big bass response”; we will determine this after running our Sennheiser CX 300-II soundtests.

Really, there's not a lot to dislike about these headphones. They fit well, have good sound quality, seem durable, and cost less than they should. We thought the CX 300-IIs were slightly more comfortable. The CX 95s' 'bent' design caused the cord to fall straight down, when it should naturally fall down and away. This led to the ear buds pulling out more easily.Though the Turbines have a better aesthetic design, they do look a bit drab compared to the CX 300-IIs. The CX 300-IIs also have a more durable design. Compare the ear buds and plugs of the two headphones. The CX 300-II has better cord guards at the ear buds and a significantly better guard at the plug. Also, the plug is bent, which helps protect the internal wires better than a straight plug. Frequency Response So Sennheiser faced a difficult task when it came to updating the CX300s. The price had to be low enough to tempt people away from the freebies, and sound quality had to be good enough to improve on the first-generation model, but not so good that they cannibalised the higher-end earphones that Sennheiser sells at higher prices. They seem to have got the balancing act just about right. They also sound amazing and can handle anything you throw at them , even at high volume they just keep performing, others just don’t come close. Slightly smoothed highs prevent the sound from ever becoming too bright or harsh. Of course, in the highest highs, the CX 300S can feel a little intense. But during most of my listening sessions, I was too busy enjoying the overall sound to notice these tiny and infrequent hiccups. Like the lows and mids, the highs abound with detail, and it’s all too easy to get lost in your favorite music with this tiny earphone. Soundstage We thought the CX 300-IIs were comfortable for a set of in-ears. Their sleeves were a bit thin, so they didn't put much pressure on the insides of our ears. Product Overview
