Design and impression outside:

The outer shell is quite thin, made of glass plastic, inside the tray is also made of plastic, in addition to a small box containing a Micro USB cable and two multilingual manual different.

Fiio K1 is designed with an aluminum casing (this shell can be replaced), the front has straight striped pattern, the back has a plastic clamp to hook this product into the shirt or pants pocket, For the clamp to move up and down, the entire surface of the device is sprayed with a needle to create a good gloss, long lasting and color as the titanium material. The top and bottom of the device are equipped with a micro USB port and a 3.5mm headphone jack. The four corners of each end are rubber coated.

K1 does not have a volume control button like some other DAC / AMP products, so it also limits the amount of friction on the volume during use, or when you put it in your pocket. move. With an impressive size of 50 x 20.5 x 8 mm, the K1 is much smaller than the regular USB model, and due to its built-in battery, Fiio K1 weighs just 11 grams. The look is quite advanced, rectangular square and compact.

Fiio tried to create the smallest earphone decoder possible, even without a built-in rechargeable battery, to maximize usability.

Understand and experience the device:

From the product design and through the company’s information, the K1 is invested by Fiio as a portable mini DAC professional, so the Plug n ‘Play feature is placed on top. Try connecting the device to a laptop / desktop computer (using Windows or Mac) via a USB cable, which will have a small blue LED next to the headset port where the device status message is being used. Similar to the test on Note 5 (Android) phone via standard OTG cable, or iOs with Apple iphone 6 plus via Lightning cable to micro USB, most are quickly identified and operate immediately without driver or any configuration (some phones do not recognize the samsung galaxy s5 example), should anyway note the convenience of the Fiio K1. It does not require charging or installation due to the use of the Savitech SA9023A USB driver.

Continue to test the ability to present the sound when plugged headphones directly into the 3.5mm output port, due to the power directly from the computer or phone, so Fiio K1 does not reach high power (about 75mW), so The device is recommended for use with “easy-to-use” headphones with an impedance of 16-100 Ω. The writer tried Audeze’s Sine headphones. When plugged in to K1, the overall sound of Sine becomes smoother and space is expanded quite well. Mid tends to be high, full and lower mid clear. Treble strips are stretched and extended, but still retain the smoothness of the original.

Fiji’s low-noise PCM5102 decoder, which receives digital signals directly from the USB and decodes at a maximum of 24 bits per 192 kHz, DAC chip This is similar to the type Fiio used in its products in Q1 and E17K. In addition, the output uses the modular TPA613321 Amplifier circuit for a sophisticated music experience, combining elements that help solve the lossless of existing smartphones.

For the smooth music, not tangled in the climax of music, more details, K1 has a plus point compared to many other competitors, because cheap products usually only concern factors such as thick bass , treble to make the sound better, not interested in the overall music. All you need to do is simply open the music on the computer or phone.

The sound of the K1 through headphones, easy to hear and quite detailed. Bass is invested, the bass strings deeper, but not as strangers as the other cheap equipment. The mid-sweet, the lyrical music more deep and smooth. Mid and bass are considered to perform very well in their duties. But in this price range, amplifier circuit can not do better, so when playing rock or edm is still quite sticky and the layers are not peeled. Treble as high as being cut horizontally, slightly harsh and a bit noise but also call it more pleasant, suitable for music lovers.

Try comparison with some other devices

AudioQuest Dragonfly ($ 149USD) is considered to be one of the best DACs / Amps on the market, in terms of level of detail and sound, the Dragonfly is higher, and the issue of powering the headphones. Dragon Fly is also better than K1.

Compared to onboard sound cards in Dell laptops, the FiiO K1 is stronger and smoother in the bass and mid.

With the same family as Q1 or E17K, the K1 is good and the detail is good, but the depth and width is not equal to 2 siblings, the sound is easy to hear and clear but lack a bit sharpness.

But at the price of the K1, this DAC / AMP product is also a good choice for users, Fiio products invest well in terms of both style and sound in the direction of popular, aimed at the new listeners. Not too heavy on technical issues, just enough to hear.
