Betron are slowly but surely becoming the brand to turn to when it comes to low cost earphones. This time, they have produced the smallest earphones we’ve ever seen – find out what we think in our Betron KS45 review.

Betron definitely have a knack for producing decent earphones at (almost) unbelievably low prices. While their earphones that we has reviewed before have varied in sound quality quite a lot – they have always offered amazing value for money. This latest offering once again fits into the ever growing sub £20 market – but this time things are a little different.

Itsy Bitsy, Teeny Weeny Earphones

Despite the price, the packaging is really quite good! The main box is made from a solid plastic with a removable lid – this could be kept for other uses/keeping the additional accessories out of harms way. The printed sleeve that wraps the box is high quality & looks very clean to the eye…some of the larger, more expensive brands could learn something here.

The most notable thing about the KS45 earphones is their size (see photo below showing a £1 coin)…or rather lack of it. They are tiny! This also means that they are incredibly light as well.

Apart from being very, very small, the earphones look to be made from aluminium and are very nicely finished indeed. The design is very simple, sleek and understated – which will appeal to a lot of people. The cable exit is nicely re-enforced with long rubber sections which should protect the cable well. The cable itself is of the woven type – this adds to the light feeling, but does transmit a little microphonic noise to the earphones from movement/rubbing etc. The cable split is again made from metal making it very tough – as is the 3.5mm straight gold plated jack plug.

Betron KS-45 EarphonesOverall the look of the Betron KS45 has been styled very nicely – and they really do look the part.

Also in the box, you get:

  • 3 sets of grey eartips (small, medium, large)
  • 3 sets of white eartips with a narrower inner diameter (small, medium, large)
  • cable clip
  • storage pouch

In use, they feel very light – and once in, they are comfortable. I found that while the white eartips sounded better, they didn’t want to stay in my ears. I normally use a medium size eartip, but with the white variants I had to use the small size & even then, they kept pushing out of my ears. This may not be the same for everyone as ears do vary a great deal. However, using the more normal medium sized grey eartips – they fitted me perfectly. Due to their size, they are also a bit more fiddly to put in place as well. It is also worth noting that I found that you need both earphones in for them to be able to support their weight…if you regularly only use a single earpiece, these might not be a great choice for you.

A Small Package That Can Deliver

Given the size and price of the Betron KS45 – there was an expectation of them not being capable of producing amazing quality sound. While this is true to a certain extent, the sound that they delivery is really very surprising.

The bass is reasonable – but it benefits from a little enhancement with EQ. With the added bass, they sound quite nicely balanced. There is some noticeable scooping in the mid-range – but that is to be expected. The mids still retain a good punch and snap which provide plenty of drive. The treble sounds  a little closed in and not as open as it could be, but again given the physical size & price – the do a very good job of it.

The sound is much better than we were expecting and they can cope with pretty much any style of music that you throw at them. Its worth noting that they work very well for speech as well (podcasts, radio etc).

Betron KS45 Review Conclusion

We think that Betron have showed that size isn’t necessarily everything – and some good things do indeed come in small packages. While there are other earphones in this price range that do indeed sound better, they aren’t all finished as nicely – nor are they as small. The small size probably does make them better suited for smaller people (and not a 6′ chap like me) – but this does make them a great choice for teens and anyone with a smaller physique. Overall the Betron KS45 offer something a little different to the norm and as a result are well worth a look.
