Build quality meets the price standard.
The overall design is elegant and luxurious.
The fit is good.
I tested it by connecting it to a Cayin N6II/E02 with AAC.
I don't know because I haven't been in crowds, but it is stable in the home. Distance tolerance is excellent, and the connection is seamless and intact even at a distance of about 5 meters. The sound is uninterrupted and music can be heard consistently, even across obstructions.
There may be a small amount of background noise, but most people probably won't notice it.
The operating interface is a touch type.

Sound quality description
The following review was tested on a FiiO M15 with an SBC connection.
FIIL CC nano has a sound signature of a full midrange.
Please see here for detailed reviews on sound quality.
Lows / Bass
Many inner-ear models are not expected to have low frequencies, and the FIIL CC nano is no exception. Even if you push it in deep into the ear and wear it firmly, you will have a hard time hearing the deepest part of the bass.
In the low frequency range, you can hear best around the punch and boom a bit higher up. Therefore, drum kicks are powerful, thick, and robust, but a bit expansive, sounding more like a punch than a thump. The sound is impactful, thick, and immersive, but not very tight.
The electric bass is a bit bright and shallow, lacking tightness.
In general, if you are looking for low-frequency quality, you should use a canal type, but if you insist on an inner-ear type, we recommend the QCY T20, for example.
The midrange is quite forward. The midrange is bright and the outlook is not bad, but the overall sound profile sounds rounded due to a weak sense of construction.
The sound is bright and transparent, but a little less tight and expansive. There is an overall sense of forward depth, and the sound is heard with the impression of extending from the back. The midrange sounds rather bright with high brightness and luminosity, and the sense of detail is not bad.
Although it sounds quite clear, it is strangely gentle on the ear, consonants are a bit less lively, and vocals and instrumental sounds are generally a bit blurred and mild, including the contours. On a positive note, it is elegant and graceful, but on a negative note, the sound lacks sharpness.
Highs / Treble
The highs do not have good extension, but the sense of detail is adequate.
The midrange lacks tightness due to a slight relative lack of overall energy, and the midrange fluffs up and spreads out, but not too much, so the sense of detail is adequate.
The highs are fairly innocuous, which will appeal to those who don't like stinginess. The sense of localization is well tuned to roll off gently, reproducing a sense of forward localization that is relatively close to the speakers.
Sound quality general comment
The FIIL CC nano has a fairly good sound balance and audio specs for an inner-ear type, and along with the SoundPEATS Air 3, is one of the most recommended inner-ear earphones in this price range. The Air 3 has a better midrange texture, but the CC nano has the edge in overall original sound fidelity.
Sound quality features
- Good sound balance
- Good original sound fidelity
- Bright midrange
- Speaker-like forward localization
- Mild highs
- Good focus on midrange
- Punchy lows
- lacks expandability
- May feel cooped up
- Lacks overall tightness
- Lacks a sense of construction
- Lacks a little in detail
The FIIL CC nano is quite an attractive earphone with a well-balanced sound in the inner-ear type, multifunctional with various presets and customizable 10-band EQ, multi-point support, good communication quality, and good battery life. The design is cool, and it is a very strong candidate for an inner-ear type in the same price range.
