Due to the fact, both models are members of the same class and they are made by the same brand, there are a few similar features. They are:

  • Key number (88).
  • Speakers.
  • Recording feature.
  • Accompaniments.
  • Rhythms.

When it comes to the size and weight, the P255 is 11 pounds heavier and the design is 5cm deeper. This means that it isn’t as portable as P115.

Quality of the sound

Here we can see the main difference. The P115 comes with a 7W amplifier and it also has a tweeter. The two speakers are 12 cm in diameter. The speakers and the tweeter are also present with the P255, but the amplifier is 150Watts which is a massive difference.

The polyphony is different as well. The P115 has 192, which is impressive for most of you, but P255 is simply better. It has 256 polyphony which is a massive difference. The sound is slightly better in general, regardless of which purpose you have on your mind. We tested both units in the same surroundings and playing the same songs, and obviously, the P255 is slightly better.

Strings do sound better on P255 and you will definitely notice the difference. The choir sounds are once again better with the most expensive model and the difference is noticeable. Voice feature isn’t supported on P115, but it is available on P255 and it is above average.

Splitting the keyboard is possible on both models, but the P255 allows for you to use more features and to use cymbal voice and piano and bass. The P115 is rather basic in this field and doesn’t allow for you this level of customization.

In a nutshell, the main difference in our Yamaha P115 vs. P255 comparison is the sound quality. The P255 is simply better and the sound is perfectly clear with a massive difference compared with P115.

Additional features

One of the interesting differences is on the keyboard. The P115 has Graded Hammer Standard keys which are made of plastics. They sound and feel great and the usage is smooth, without any issues. It is simply stunning how Yamaha was able to make this possible.

The P255 has keys made of synthetic ivory and they are even better. They feel almost as realistic as the ones on acoustic pianos and they are pleasant to use. The overall experience is a quieter (significantly) and feels better, more expensive as well.

Don’t forget that P115 has sound boost which will enhance the effect in live performing. The P255 doesn’t have the same system. It has professional-grade EQ which allows the musicians to carefully adjust the effects. The P115 is decent with the feature in question, but the P255 is slightly better.

The P255 allows for you to record 10 sounds, it comes with 24 different voices and you can play music using your device. There is a USB port that is useful and very convenient. The P115 has 10 voices and it can record one song. There is no option to use your device due to the fact there is no input option.


In the end, we must tell you the verdict of our Yamaha P115 vs. P255 comparison. The P115 is ideal for beginners and intermediate users, while the P255 is better for intermediate and professionals. Don’t forget that it is almost twice as expensive and it is made to meet the requirements of more demanding users.
