Quick Answer:

Both come from Kala and both are sensible first ukuleles. The KA-15S is a soprano, the smallest and most traditional size, with the classic bright plinky voice. The MK-C is a concert, slightly larger with wider fret spacing and a fuller sound. Adults and older children generally find the concert easier to play, and a young child usually suits the soprano.

Why geared tuners matter on a cheap ukulele

Very cheap ukuleles use friction pegs, which slip and make the instrument impossible to keep in tune, and nothing frustrates a beginner faster than an instrument that will not stay tuned. Both of these use geared tuners, which hold. If you are looking below this price, that is the specification to check first, because it decides whether the instrument is usable at all.

Choosing a size by hand size

Soprano ukuleles have very tight fret spacing, which suits small hands and cramps adult ones. Concert instruments give a little more room between frets without becoming a different instrument. If the player is an adult or a teenager, concert is usually the more comfortable choice. For a child under about ten, soprano is generally right and also lighter to hold.

New strings are worth changing

Ukuleles at every price ship with strings that stretch for the first week or two and then settle, and the supplied strings on budget instruments are often the weakest component. A set of good strings costs under fifteen dollars and makes a noticeable difference to tone and tuning stability. It is the cheapest upgrade available on any ukulele.

Both are the same tuning

Soprano and concert ukuleles are tuned identically, so everything learned on one transfers directly to the other. Chord shapes, songs and technique are the same. The choice is about comfort and sound rather than about learning two different instruments, and moving between them later takes no adjustment at all.

Our Verdict

For a child, the soprano KA-15S is the traditional and usually correct choice, and it is cheaper. For an adult or an older teenager, the concert MK-C is more comfortable to play and sounds fuller, and the extra thirty dollars is well spent. Both are from a reputable maker with geared tuners, which is the specification that separates a real ukulele from a toy.

Frequently Asked Questions

Is a ukulele actually easier than a guitar?

For a beginner, generally yes. Four nylon strings under low tension are gentle on fingertips, and many songs need only three or four simple chord shapes, so a complete beginner can play a recognisable song in a first sitting. That early success is a large part of why ukulele is recommended for children and for adults who have tried and stopped before.

What else should I buy with a ukulele?

A clip on tuner, a gig bag and a spare set of strings, and that is genuinely all. Many of these are sold as bundles that include them. A strap is optional on a soprano and useful on a concert for standing up. There is nothing expensive in the accessory list, which is another reason ukulele is an easy instrument to start.

How long do the strings take to settle?

New ukulele strings stretch for the first week or two and go out of tune constantly during that period, which is normal rather than a fault. Tune it every time you pick it up and it will settle. Explaining that in advance to a child saves a lot of frustration in the first fortnight.
