The EX1 in ear headphone is created from CNC milled, with the back made of anodized duralumin and the front stainless steel and has killing looks.
The headphone features Nanotech titanium diaphragm driver at its core and can handle high power without distortion unlike traditional diaphragms found in many headphones. The cable is Kevlar-reinforced, and the 3.5mm plug housing looks durable.
The small rounded angled nozzles are ergonomically designed to ensuring maximum comfort over longer listening periods and also offers a higher degree of isolation.
Unlike rubber cable, FiiO Ex1 comes with an all transparent sheathed cable from jack to earphone. The EX1 is designed to be worn cable down and we did not find any issues even when lying or sleeping with headphones plugged in, though you can also wear these over-the ear. The Y-Split is metal and slides up and down to form a cinch. The cinch can effectively shorten the length of the cable after the Y split to keep the earphones in place more securely, especially with over-the-ear wear. When cables come out in front of your neck, cinch the cable very gently for a comfortable fit; when wearing the cables behind the neck, cinch tightly for a very secure fit.
To drive maximum comfort and great sound, correct selection of eartips is necessary and to ensure this, the EX1 comes with several sets of eartips of different sizes and designs to let you find the best fit, both physically and sonically.
Performance
To review the audio performance of EX1 we played various genres of tracks, and we did not find any weakness anywhere. On tracks with intense sub-bass content like "Can't Hold Us" by Macklemore & Ryan Lewis, the EX1 delivered bass beats vigorously complementing the pace of the lyrics and will surely captivate you. The EX1 remains distortion free even at top volume levels. Drums, piano, whimsical handclaps all sounded pleasant making this melody truly entertaining to listen with EX1.
If your music library includes hip hop , electronica and demanding bass, this is going to be the headphone for you. On classical tracks and on Opera it sounded rich, fuller and balanced. Also on Bill Callahan's "Drover" vocals sounded rich in the mid-lows with higher frequencies maintaining bright presence throughout and with ample balance.
