How we ranked these studio monitors
Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

Buying advice: studio monitors for keyboard
Match the low-end reach to your keyboard
Keyboard low notes need speakers that reach low. The PreSonus Eris Studio 8 reaches 35 Hz and the JBL 305P MkII reaches 43 Hz; compare the low-frequency reach figures before you buy. A larger woofer tends to pair with a lower reach figure, as the 8-inch PreSonus shows.
Check the inputs your keyboard needs
Keyboards send sound over 1/4-inch line outputs, so a monitor with 1/4-inch TRS inputs is the simple match. The JBL 305P MkII and the PreSonus Eris Studio 8 both list balanced XLR and 1/4-inch TRS inputs, while the Pioneer DM-50D-BT centers on Bluetooth. If you play and record, XLR and TRS let you wire the monitors into an interface or mixer.
Decide between a single speaker and a pair
The JBL 305P MkII and the PreSonus Eris Studio 8 are sold as single speakers, so a stereo pair means buying two units. The Pioneer DM-50D-BT ships as a pair in one box. A single speaker works for mono practice, while two speakers give a stereo image. The JBL notes a broad sweet spot when used in pairs, and the PreSonus lists a wide sweet spot from its EBM waveguide.
Frequently asked questions
Can I plug a keyboard straight into studio monitors?
Yes, if the monitor has the right input. Keyboards send sound over 1/4-inch line outputs, and both the JBL 305P MkII and the PreSonus Eris Studio 8 list balanced 1/4-inch TRS inputs. Run the keyboard outputs into the monitor inputs and set the monitor volume.
Do I need a pair of studio monitors for a keyboard?
One monitor gives you mono sound, while a pair gives a stereo image. The Pioneer DM-50D-BT ships as a pair, so one box covers you. The JBL 305P MkII and the PreSonus Eris Studio 8 are sold as single speakers, so you buy two units for stereo.
Should a keyboard player buy an 8-inch monitor?
An 8-inch woofer reaches lower than a 5-inch one, so the PreSonus Eris Studio 8 suits players who want more low end from the monitor itself. The trade is size: it weighs 19.9 lb against the JBL's 10.1 lb. If desk space is tight, the 5-inch JBL 305P MkII still reaches 43 Hz.
Can I use these monitors with a computer too?
Yes. The JBL 305P MkII title names desktop computer use, and the PreSonus Eris Studio 8 lists desktop and laptop as compatible devices. The Pioneer DM-50D-BT adds Bluetooth for wireless listening from a phone or tablet.
