The FiiO FD1 is an entry-level in-ear monitor (IEM) characterized by a single 10mm beryllium-plated dynamic driver and dual N50 magnets. Priced at approximately $59.99, it provides remarkable performance for its segment with a sound profile that includes a well-balanced bass, clear mids, and nuanced treble. The earphones come with a variety of accessories, including a durable carrying case, multiple pairs of ear tips, and a sturdy 4-strand monocrystalline copper cable. The overall construction utilizes plastic for the main body with a metal nozzle, contributing to both comfort and lightweight wearability. The FD1 has a frequency response ranging from 10Hz to 40kHz, a sensitivity rating of 109dB/mW, and an impedance of 32 Ohms. Its performance is enhanced by its capability to be driven by portable devices while also benefiting from amplification. Reviews have noted its immersive soundstage, articulate bass, and rich vocal presentation, making it a strong contender in the under $100 range for audiophiles and casual listeners alike.
