Thank you for viewing! I am selling the high-performance portable headphone amplifier "Q3" from FIIO. ◾️Product Condition and History I purchased this as a used item in good condition from an audio gadget specialty store last March. I have used it with care, but recently, due to changes in my lifestyle, I have been using it less frequently, so I have decided to sell it to someone who can make good use of it. ◾️Major Features of the Product 1. High-quality sound with THX AAA amplifier circuit Equipped with a THX AAA amplifier that minimizes sound distortion, dramatically upgrading the sound from smartphones and PCs to a clear and powerful sound. 2. Versatile connection terminals and Hi-Res support Supports 2.5mm/4.4mm balanced connections. Furthermore, it can fully play the latest Hi-Res audio sources (PCM/DSD), making it a highly functional unit despite its compact size. ◾️Condition • Operation confirmed. Contact of each connection terminal is also good. • It was mainly used indoors, so there are no noticeable major scratches, but please consider this as a used item. • Stored in a non-smoking, pet-free environment. Alcohol disinfection will be performed before shipping. ◾️Accessories • All accessories are included except for the warranty. • Everything in the photos is included, so please be sure to check before purchasing. ◾️Shipping Due to work commitments, shipping is scheduled for Saturdays and Sundays. As it is precision equipment, it will be carefully packed with bubble wrap, etc., before shipping. Immediate purchase is possible. Thank you. #FIIO #Q3 #PortableAmp #HeadphoneAmp #HiRes
