Which is better for recording an acoustic kit?

The EAD20. Its bass-drum mic and trigger pickup capture the whole kit, and its 8-in/10-out USB interface records multiple channels to a computer. The TD-27 is built for electronic pads.

Which has more sounds?

The EAD20 lists 2,203 voices against 728 drum sounds on the TD-27. The TD-27 counters with modeled Prismatic sounds and WAV sample import.

Can the TD-27 be used with an acoustic kit?

Not directly. It has trigger inputs for pads, not a built-in microphone, so you would need separate mics and triggers to capture an acoustic kit.

Does the EAD20 work without a computer?

Yes. It has a looper, sampler and playback functions and can run standalone, though its USB audio interface needs a computer for multichannel recording.

Is the TD-27 worth it over the EAD20?

Only if you play an electronic kit. It adds Bluetooth, MIDI, an SD card slot and a real-time recorder that the EAD20 does not list. For acoustic kits the EAD20 does more.

Both are solid-state modules with no moving parts, so lifespan depends on use and care. Neither maker publishes a rated life, so buy on features rather than durability claims.

Roland TD-27 V-Drums Sound Module vs Yamaha EAD20 Electronic Acoustic Drum Module

The TD-27 is the module to buy if you are building or upgrading an electronic kit and want modeled drum sounds, per-pad trigger inputs, Bluetooth and SD card sampling. The EAD20 is the pick if you want to add electronic sounds and recording to an acoustic kit without replacing it.
