The pianos work with battery power so you can easily take the instruments outside to play.  

The front side of the piano instruments is the same. The keyboards feature a clear LCD screen where learners can read the notes and learn to play the piano easily. Both the pianos share a few musical features as well. For instance, they boast 400 sounds, 100 types of rhythms, and 60 present demo songs. Beginner users of both the pianos will have an equal number of demo songs and sounds to play. They won’t find any difference in that aspect.

Major Differences Between Casio LK 265 VS Casio CTK 3500

While Casio LK 265 and Casio CTK 3500 appear similar, they are different in a lot of ways. Casio CTK 265 is an unweighted action keyboard while the CTK 3500 is semi-weighted action. This means the feel of the piano keys is different when dealing with these two instruments.

When playing Casio CTK 3500, the keys depress easily, but they don’t rise back up as effectively. If you have to play precise piano techniques such as a glissando on this piano, it won’t be fun to do. On the contrary, with the unweighted action of the CTK 265, you can indulge in precise playing, which means you can easily play contemporary music styles on this piano.

There is also a difference in connectivity in the LK 265 and CTK 3500. While both the pianos feature ports to connect headphones and TRS Aux Input, there’s none for connecting the mic to the CTK 3500. However, you can connect a mic to the LK 265 and sing along while playing the piano. On the other hand, the CTK 3500 has a USB to Host port, which is missing in the LK 265. This connectivity option lets you connect any external device (your smartphone or iOS) to your keyboard and transfer songs to play or share with others.

The practice feature of the Casio CTK 3500 is also slightly different from the LK 265. The former comes with Lessons and Metronome, while the LK 265 has the Lighted Key Guide in addition to Lessons and Metronome. The Lighted Key Guide feature is beneficial for learners. They can learn how to play the piano with lighted keys. The keys blink one by one for beginners to guide which key to press first and which one to play next and so on. For this feature, Casio LK 265 is known as the “light-up keyboard.”

Casio LK 265 is slightly more expensive than Casio CTK 3500. The price range of the LK 265 is $159.99, while that of the CTK 3500 is somewhere around $139.99.
