General Caveats with Budget Projector Audio

While not specific to the PJ04, user experiences across similar low-cost, compact projectors highlight common

“Cheap projectors … loud fans, the cheap curved corners, the crappy colors, etc.”

These suggest readability can suffer due to underwhelming acoustic design and poor sound output. Low brightness and reliance on low-cost components also indirectly impact overall perceived quality—including dialogue intelligibility.

Summary: Readability Assessment

Verdict

The Earldom PJ014s built-in speaker is probably adequate for casual, low-volume use in quiet environments (like personal viewing). But for clear dialogue during movies, presentations, or group viewing, it’s unlikely to provide satisfactory audio performance on its own.

To improve readability:

Use the audio output to connect a soundbar, Bluetooth speaker, or external speakers.

Keep volume moderate and room noise low for better speech clarity.
