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 All too often these sort of in-canal earphones, where the rubber earpiece tips sit in and seal against the outer edge of your ear canal, are scuppered by not reaching far enough into the ear to get a good seal – at least, not without being pushed uncomfortably far in. 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. If you're looking for an affordable, decent-sounding pair of earbuds, start with the Sennheiser CX 300. Sennheiser's first in-ear design sounds like a winner to us.

The Sennheiser CX 3.00 are almost the perfect entry-level earphones. They’re incredibly light and comfortable, and just easy to get on with. However, they’re very bass-heavy, so only really for casual listening unless you’re seriously into low frequencies. Their price needs to drop a little, too.

These Sennheisers, then, fit in totally effortlessly, providing an instant and utterly comfortable seal with the default medium-size eartips. 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. The CX 300S presents a fairly spacious soundstage. Though you can’t call the sound experience holographic, there is some depth there. And imaging is precise enough to hear degrees of width with respect to instrument placement. SUMMARY Call quality remains succinct and accurate enough, with my voice registering clear and crisp.

CX 300S | Sennheiser

Originally released in late 2008, Sennheiser's CX 300 II Precision earphones are some of the oldest models on the market from the CX Line, but continue to deliver in almost every aspect. For those looking for a high-performance pair of earphones within budget, these are certainly worth considering. Features & Sound The most obvious thing about the CX 3.00 design is that Sennheiser has moved from a straight earpiece to one with a slight angle to it, and this makes all the difference to how well they fit, as well as the resulting comfort and sound quality.

About Us

These are not the best headphones you can buy, but they are incredibly good value. With plenty of volume and a big, meaty sound, it looks like Sennheiser has another hit on its hands. The cable lengths for each ear are identical and there’s a little sliding woggle for tightening the cables up under your chin – like all the cool kids do nowadays. But let’s be clear, these are a huge upgrade over most in-the-box earphones and they’re specifically aimed at those who like their bass – in that regard they live up to their billing. Due to the perfect fit and lightweight nature of these earphones, we found we could wear them almost indefinitely. The sealed nature of them means you sometimes want to let your ear breathe every now and again, but otherwise they’re just a joy to wear. We even found we could sleep with them in, with them not pressing on our ears when resting on a pillow.
