Main trade-off
Casio PX-S6000
The shallow body does not include the stand, a half-pedal setup or a live USB-audio interface.
Head-to-head
Choose PX-S6000 for a shallow battery-capable setup and a microphone input. Choose P-525 for direct computer USB audio, the included FC3A continuous damper pedal and more separate onboard MIDI tracks. Casio’s bare body is 134 mm shallower, but its SP-3 pedal is only a switch and computer USB carries MIDI rather than sound. Both need a separately suitable stand. Yamaha’s complete input list has no microphone connection.
Before you choose
PX-S6000 saves 134 mm of bare-body depth, which can be valuable on a shared work-and-music desk. If you want to record its own piano sound live into computer software, though, the USB-MIDI connection will not carry that sound. You need an appropriate audio-input route from the line outputs or a different file-transfer workflow. P-525 uses more depth but supplies USB audio. Measure the complete arrangement, including the support and any audio equipment, before deciding which purchase leaves more usable space.
What this is based on
376 minus 242 = 134 mm, with music rests excluded. Exact computer USB roles distinguish sound from MIDI. No dimensions are assigned to unknown extra equipment.

Main trade-off
The body is 376 mm deep before the rest and needs AC. A microphone needs a separate suitable input route.


PX-S6000 or P-525 for a shared room? Compare recording connections, singing, half-pedal practice and the space required by the whole setup.
These premium weighted base pianos sit in a realistic cross-shop for home players moving beyond an entry instrument. Casio emphasizes a shallow, battery-capable body while Yamaha provides direct computer audio and a continuous pedal.
Winner by situation
242 versus 376 mm before rests, supports and cables. Check the full arrangement.
Yamaha includes FC3A. Casio needs a documented optional continuous-pedal setup.
P-525 has USB audio. Casio’s MIDI port does not send its internal sound.
Casio combines mic input and battery operation. Check support, pedals and realistic battery conditions.

If a teacher wants a learner to practice gradual damper control, P-525 supplies an FC3A pedal that supports it. PX-S6000 supplies the SP-3 switch, so the documented optional half-pedal setup belongs in the comparison price. This is especially easy to miss when the Casio microphone and performance controls make it look like the more complete box. Neither base piano includes furniture and all three pedals. Price the exact lesson-ready setup before spending the budget on features used only occasionally.
US accessory lists distinguish the continuous FC3A from SP-3 and optional Casio SP-34. No current accessory price or universal teaching requirement is assumed.
One family member may use headphones for lessons while another wants to sing with the piano. PX-S6000 supplies a mic input and can use batteries at another suitable location, which can help move the singing session away from a work call. P-525 has two headphone sockets for shared listening, but its stereo AUX IN is not a direct substitute for a microphone preamp. Neither headphone arrangement makes a person’s singing quiet. Choose Casio when the singing and relocation are real weekly jobs, and Yamaha when stationary practice and recording dominate.
Casio mic and battery specifications, both models’ two headphone sockets, and Yamaha’s complete input list and AC supply. No measured room-noise or runtime claim.

Casio, PX-S6000BKC3
You need a 242 mm deep bare keyboard body and can plan a suitable stand, pedals and cable clearance.

Yamaha, P-525
Lessons require gradual damper control and you want the FC3A continuous pedal included.
Meaningful differences
| What changes | Casio PX-S6000 | Yamaha P-525 | Why it matters |
|---|---|---|---|
| Body depth before rest | 242 mm | 376 mm | Casio saves 134 mm of keyboard-body depth, before support and recording equipment. |
| Computer recording | USB-MIDI, no live USB audio | USB audio and MIDI | Recording a software instrument differs from capturing the hardware piano sound. |
| Supplied pedal | SP-3 switch | FC3A continuous damper | A teacher’s half-pedal requirement changes the ready-to-practice shopping list. |
| Singing connection | Dynamic microphone input | Stereo AUX IN, no mic input | Yamaha requires a suitable line-level feed for that input. |
| Away from AC | Optional eight AA batteries | AC adapter | A change of room needs safe support as well as a power plan. |
| Separate MIDI parts | Two tracks | Sixteen tracks | Two-hand practice already fits two parts. More parts matter for a larger arrangement. |
What you give up
Recommendation switch
Choose Casio PX-S6000. PX-S6000 combines the mic connection with a shallow, battery-capable body.
Choose Yamaha P-525. P-525 includes the pedal and USB-audio route needed for those jobs.
Choose neither. Neither selected base configuration includes that complete setup. Compare the correctly matched accessories or a documented furniture package.
What matters in practice
You want a piano that fits around family life, but saving room on the keyboard can leave you buying extra equipment for lessons or recording.
