We recommend reviewing this instruction manual in its entirety before using your EAR3MK2 Mobile Amp.
It introduces and explains the EAR3MK2’s features, how to set them up, and correct operation for a rich user
experience that you come to expect from the best performing amp on the market today.
Any changes or modifications to this product not expressly approved by IASUS Concepts Ltd. could void the
1-year limited warranty. Should there be any questions or concerns about modifications, please contact IASUS.
Do not operate your device at high volume levels when using the EAR3MK2 Amplifier. Hearing experts
advise against continuous exposure to high volume levels. If you experience ringing in your ears,
discontinue using the EAR3MK2 immediately.
Do not turn the volume up too high on the EAR3MK2. This amp has the potential to damage headphones,
earphones, helmet speakers, etc. should they not be rated for a higher audio input. Use the volume
amplification carefully by increasing the volume slowly. Proceed with caution to avoid over boosting your
headphones, earphones, helmet speakers, etc., but most importantly, to avoid permanently damaging
your hearing.
