Fiio, best known for its high-resolution media players and portable headphone amplifiers, recently launched the second generation of its premium EX1 earphones. The successor to the EX1 promises improved audio quality and better craftsmanship.
At Rs. 4,299, this pair is a bit on the expensive side for earphones with dynamic drivers. However, let's see if the new EX1 manages to win us over.
The EX1 (2nd Gen) ships with fairly good packaging. You get six pairs of silicone ear tips (we only had one pair with our review unit), a clip, a carry case, a quick start guide, and a warranty card. The carry case is a bit too shallow, which means you need to take extra care when putting the headphones in and taking them out.
The enclosures are made from both stainless steel and aluminium alloy which makes them light, but they should still be able to withstand the wear and tear of daily use better than most plastic enclosures. The glossy finish makes the Fiio EX1 (2nd Gen) look really good and there are blue and pink rings around the left and right earbuds respectively, which makes it easy to identify which is which. There are also clear markers for the left and right earbuds printed on the inside.
The Fiio EX1 (2nd Gen) features a tilted in-ear design, which makes it a lot easier to wear these earphones. You get a 1.2m polyurethane cable, which is durable and doesn't tangle too easily. However, it's sometimes tough to get it to uncurl after being rolled up for a long time. The cable terminates into a gold-plated L-type 3.5mm headphone jack. There's a cable tie attached to the bottom of the cable, which is handy for wrapping it up when you don't have the case with you.
The cable has an in-line control pod with the microphone and media controls. The pod itself is built well but the buttons are fiddly and feel cheap. There aren't any proper markings on the buttons to help you identify them.
One of the reasons for the high price of the Fiio EX1 (2nd Gen), we think, is the material used for the driver's diaphragm, which is titanium. This material is light and can vibrate efficiently, which should result in overall better audio performance.
In terms of specifications, the Fiio EX1 (2nd Gen) has a frequency range of 20Hz – 40kHz, and impedance of 13Ohms. The drivers are 13mm each, and the whole unit weighs 18 grams.
The tilted design of the earphones makes them incredibly comfortable to wear with nearly no fatigue after an hour of continuous listening. They're also incredibly light so you'll barely feel them in your ears. The cable is long enough for most use cases and we didn't face any issues with durability during our two weeks of testing. We also found the microphone to be very good for phone calls.
The media buttons don't have a very reassuring feel to them and volume control isn't supported for iOS devices. Other than that, they functioned well across Android devices.
Straight out of the box, the earphones sound great with a nice wide soundstage and balanced tone. Our unit wasn't sealed and may have passed through other hands, so your out-of-the-box experience might vary. The EX1 (2nd Gen) is also ‘Hi-Res Audio' certified and it shows, as it reproduces FLAC files very well. We tested it on an HTC 10, a OnePlus 3T, and an iPad and it performed equally well in all the devices. The earphones do leak sound a bit but not too much.
The EX1 (2nd Gen) excels with upper- and mid-range frequencies. Vocals sound detailed and crisp which is evident in tracks like Anywhere by Passenger. The high notes can sound a bit shrill at times but we didn't find this to be the case across all tracks. The low impedance also allowed us to easily drive these earphones with our test smartphones without having to raise the volume very high. These earphones do well with bass-heavy songs too, without getting boomy. In tracks like Believer by Imagine Dragons, the tight bass is handled surprisingly well without any distortion even at high volumes. Acoustic separation is also very good.
The Fiio EX1 (2nd Gen) is a very good pair of earphones, and even though it costs a slight premium at Rs. 4,299, you won't be disappointed. A similar amount could also fetch you a pair of balanced armature earphones like the Brainwavz B100, which sound a bit cleaner due to the low emphasis on bass response. If you want that extra oomph in the low end, the EX1 (2nd Gen) fills that role nicely. These earphones have excellent build quality (barring the buttons on the remote), look great, and have a nice balanced sonic signature.
