Main trade-off
Casio CDP-S360
The WU-BT10 Bluetooth adapter is optional, not included in the selected base piano.
Head-to-head
Choose the PX-S3100 for included Bluetooth, two headphone listeners and dedicated line outputs. Choose the CDP-S360 for an accompaniment-focused setup where a longer rated battery session matters more.
Before you choose
Both list 200 rhythms, but the PX-S3100 includes its WU-BT10 wireless adapter. The CDP-S360 needs that accessory separately. If your backing tracks and settings live on a phone, compare the complete package cost before treating the lower base-piano price as the final saving.

The manufacturer's alkaline-battery estimate is about two hours under its conditions.


Casio CDP-S360 vs Casio PX-S3100: compare headphone sockets, included bluetooth audio reception, dedicated line outputs and the practice routines that change the better choice.
Both offer 700 tones and 200 rhythms in a 232 mm-deep battery-powered body. Their included wireless hardware and output connections are the more useful differences for a real setup.
Winner by situation
Both list 200 rhythms, but the PX-S3100 includes its WU-BT10 wireless adapter. The CDP-S360 needs that accessory separately. If your backing tracks and settings live on a phone, compare the complete package cost before treating the lower base-piano price as the final saving.
The PX-S3100 supplies two headphone connections plus dedicated line outputs. CDP-S360 uses one shared phones/output socket. Count whether the second connection is for a listener or amplification. They are different jobs, and a shared jack can become the bottleneck even with many built-in sounds.
Casio's alkaline estimates are about four hours for CDP-S360 and two for PX-S3100. Actual use varies. For a player moving to an outlet-free corner, the simpler model's stated runtime may matter more than extra connection hardware. Both keep the same 232 mm bare depth.
The CDP-S360 lists six tracks and PX-S3100 three. Check each recorder's part rules and save limits for the arrangement.

Casio, CDP-S360
The CDP-S360 fits accompaniment, a six-track MIDI recorder and battery operation into a 232 mm-deep body. Budget for the wireless adapter if phone streaming is part of the plan.

Casio, PX-S3100
The PX-S3100 puts 200 accompaniment rhythms and a three-track recorder inside the same 232 mm depth as the simpler PX-S1100. Dedicated outputs support a separate speaker setup.
Meaningful differences
| What changes | Casio CDP-S360 | Casio PX-S3100 | Why it matters |
|---|---|---|---|
| Headphone sockets | 1 | 2 | Count physical listeners and check plug sizes and mode routing before planning a shared session. |
| Included Bluetooth audio reception | No | Yes | Audio reception carries backing music from a supported device, not sound to wireless headphones. |
| Dedicated line outputs | No | Yes | Dedicated outputs keep an external amplification route separate from the headphone sockets. |
| Internal recorder tracks | 6 | 3 | Track allocation and independent overdubbing matter more than a large number alone. |
| Manufacturer battery estimate | About 4 hours under manufacturer conditions | About 2 hours under manufacturer conditions | Manufacturer estimates use their own conditions and do not establish matched runtime. |
What you give up
Recommendation switch
Choose Casio CDP-S360. Casio's alkaline estimates are about four hours for CDP-S360 and two for PX-S3100. Actual use varies. For a player moving to an outlet-free corner, the simpler model's stated runtime may matter more than extra connection hardware. Both keep the same 232 mm bare depth.
Choose Casio PX-S3100. Both list 200 rhythms, but the PX-S3100 includes its WU-BT10 wireless adapter. The CDP-S360 needs that accessory separately. If your backing tracks and settings live on a phone, compare the complete package cost before treating the lower base-piano price as the final saving.
Choose neither. The manufacturer records do not provide a matched test for those outcomes. Try the instruments in your intended conditions.
