Our take on the RockJam 61-Key Black Electronic Keyboard Piano with Sheet Music Rest, Piano Note Stickers & Lessons

The RockJam RJ640 is a 61-key portable keyboard aimed at beginners and casual players. It runs on wall power or six AA batteries, has built-in speakers, a headphone jack for quiet practice, a mic input, aux in and USB-B and MIDI outputs. Its 350 tones and 350 rhythms plus 50 demo songs and a 46-note recorder give more variety than most starter keyboards, though it has no touch-sensitive keys, no pitch bend or modulation wheel, and no drum pads. Owners rate it well as a first keyboard and for practice; serious players will want weighted or velocity-sensitive keys.

  • FeaturesPraisedThe headphone jack, mic input, recorder and large tone and rhythm library are valued at this level.

Questions and answers

Is the RockJam RJ640 good for a beginner?
Yes. It has 61 full-size keys, a learning mode, note stickers and lesson access, and the headphone jack lets beginners practice quietly. The keys are not touch-sensitive, so it will not build dynamics the way a weighted piano does.
Can it run on batteries?
Yes. It runs on mains power with the included adapter or on six 1.5V AA batteries, which are not included. Battery power makes it usable away from a socket.
Does it have touch-sensitive keys?
No. The 61 keys are not velocity-sensitive, so volume does not change with how hard you play. Players who need dynamics should look at a keyboard with weighted or touch-sensitive keys.
Can I use headphones and a microphone at the same time?
Yes. It has a 1/8-inch headphone jack and a mic input, so you can sing along while listening privately through headphones.
What connections does it have?
It has a 1/8-inch headphone jack, a mic input, an aux in for phones and tablets, a 1/4-inch output, MIDI and a USB-B port. These let it connect to a computer, an amp or a mobile device.
What is in the box?
The keyboard comes with a sheet music rest, piano note stickers, a power adapter and access to lessons through the Simply Piano app. Batteries and a microphone are not included.
