The Sennheiser CX310 Originals use sound-isolating rubber tips, but as they're not designed to be pushed as far into your ear as some IEM earphones, noise isolation isn't deafening. It'll do the job for most common noisy environments though, reducing the clatter, rumble and bustle of trains, buses and noisy office environments to a background murmur.

The rubber tip still has to form a seal, but here it's with the opening of your ear canal rather than half-way in. People put off by the invasive feel of IEM earphones often find this design easier to live with.

These buds share the same sound signature as the Sennheiser CX300 range, with a warm, full low-end that makes most music sound rich and involving. They aren't particularly critical earphones, but they have a knack of making your music sound pleasant. It's the key to the success of the CX series, along with its affordable prices.

The bass doesn't extend to impressive depths and isn't incredibly fast, but it doesn't boom out like many other budget IEMs. Treble resolution and detail is also limited, with less crystalline insight on offer than in the Ultimate Ears 200 for example. However, the resulting sound is just so cohesive and enjoyable that these observations don't stick in your mind after a brief listen. The Sennheiser CX310 Originals earphones have a touch too much bass to offer a truly balanced sound, but it's a subtle point and the overall enjoyment certainly makes up for it.

That said, typical of what Sennheiser calls the CX310 Originals' "bass-driven sound", these buds can get lost trying to recreate intricate detail - which is particularly evident when listening to more complicated or dense classical pieces. That slight over-blown bass presence can leave subtler woodwind and string instruments pitched in a battle they can't win against the larger-bodied string players and timpani.

The Sennheiser CX310 Originals have a crowd-pleasing sound, and we think most will be duly pleased by it. If bass was slimmed-down just a tad, they'd be more accurate, but when most of our ears are trained to perk-up at the additional excitement offered by a beefy low-end this may also make them less fun, less enjoyable.Sennheiser CX310 Originals

Available for around £35, the Sennheiser CX310 Originals are entry-level earphones. Our issue is that other CX-series earphones, those without Adidas logos competing for space on each bud, are available for less. Even the CX400 Precision II, which come with a volume control and more tips, are cheaper if you shop around. Just make sure you like the blue colour enough to warrant that extra £10 or so before buying.

Verdict

The CX series has become renowned for offering great upgrades to bundled earphones that won't cost the earth. These Sennheiser CX310 Originals are a worthy addition to the range, offering that familiar warm, bassy sound. Predictably, the "style" element of these earphones has ramped-up the price slightly though, so the vanilla CX300 or CX400 models may be a better buy for the cash-strapped.
