Kawai CN37chat_bubble_outlineFrom real comments

The sound quality draws strong praise from those comparing it to other pianos. One commenter deliberating between the ES110 and CN37 calls the CN37 one of the most inspiring piano sounds they've ever heard, describing it as warm and superior even to the impressive ES110. Another user weighing the CN37 against the CS-11 notes the CN37 has cool extra features worth trying. This positions the CN37 favorably against both lower and comparable-tier alternatives on sound alone.

A recurring key-action fault is the most serious concern raised by owners. Multiple commenters independently report keys developing a plastic-like, clicky sound after weeks of use. One owner, who had the same issue with the predecessor CN-35 (repaired twice before Kawai replaced it with the CN37), says the identical fault reappeared on the CN37 and Kawai now denies it's a defect, refusing warranty repair despite advertising a 5-year warranty. This pattern across two models and two users signals a real reliability risk rather than an isolated incident.

The side-mounted control layout is a step down in usability from the previous model. A commenter comparing the CN37 demo to the CN35 demo says having all buttons on the side looks neater but is harder to use, forcing the player to lean to one side during operation. They also note the CN37 demo doesn't show switching between sounds the way the CN35 demo did. Combined with Bluetooth being unavailable in their comparison, this user opted to stick with the CN35 instead.
