Roland RH-300 Headphones - Black

The Roland RH-300 headphones have a frequency range of 10 to 25,000 Hz, offering a broad spectrum of sound reproduction.

While designed for music monitoring, their accurate sound reproduction and isolation can be beneficial for gaming where detail and immersion are important. However, they do not feature a microphone.

Yes, you can use them with smartphones that have a 3.5mm headphone jack. If your smartphone uses a USB-C or Lightning port, you will need an appropriate adapter.

The product information does not explicitly state the impedance, but the maximum input power is 1600 mW and sensitivity is 101 dB, indicating they are designed for direct connection to typical audio sources.

The product description mentions a 'Pouch: Yes', suggesting a carrying pouch is included for protection and portability.

The newly developed 45mm driver with a neodymium magnet provides a full dynamic range and stable output, allowing the headphones to reproduce sound accurately, even with high input surges and fast attack transients.

The closed-back design provides excellent passive noise isolation, helping to block out external sounds so you can focus more clearly on your audio.

Ensure the cable is securely connected to both the headphones and the audio source. Check that the volume on the audio source is turned up. Test with a different audio source or device to rule out an issue with the headphones themselves. Ensure the correct jack (3.5mm or 1/4" adapter) is being used.

Check the audio source's output level; it may be too high, causing clipping. Ensure the cable is not damaged and is fully inserted. Clean the headphone driver mesh gently if accessible, but avoid applying pressure.

Verify the volume settings on both the audio source and any intermediate devices (like an amplifier or mixer). Ensure the headphone sensitivity (101 dB) is being driven by an adequate source. Test with a different source known to produce sufficient volume.

Adjust the headband for a snug but not overly tight fit. Ensure the earcups are positioned correctly over the ears. Take periodic breaks during extended listening periods.
