1. Appearance

The illustration on the box cover reflects a specific cultural style, with a graffiti-like layout that makes one feel immersed in a wild rhythm. The box material is very good and can be opened directly. The internal illustrations are all related to music, sports, and entertainment, instantly activating the athletic hormones in young people. The overall arrangement of the earphones is neat and clear. On the left is the main part of the earphones, and on the right are three sets of spare earplugs in large, medium, and small sizes to fit different ear shapes. There is also a mini earphone storage box that is easy to carry. The storage box is exquisitely crafted and made of leather. At the bottom of the box, there is a 1.5-meter-long Micro USB data cable. The data cable is of excellent quality. Additionally, there is a detachable earphone stand and a bilingual user manual in English and Chinese. The accessories are simple but practical.

2. Parameters

In terms of basic parameters, the Codoon earphones use a 9mm single dynamic driver unit, high-tech composite diaphragm, 16Ω impedance, frequency response of 20Hz-25kHz, sensitivity ≥105dB, channel difference <1dB. Charging takes about 2 hours, and the light-up time during use lasted for about 3 hours over two runs. The battery is a 3.8V (250mAh) lithium polymer.

3. Experience

The appearance is soft, the material is non-radiative, and the cable feels very resilient and of good quality. The light-up cable is an LED strip, which enhances safety during night runs. For someone who loves night running like me, it is a great safety feature. The blue light is eye-catching, and the return rate during runs is very high. Wearing it for a long time does not cause any discomfort to the ears; in fact, it feels very comfortable.

4. Sound Quality

Compared to previous Bluetooth earphones from Taobao and the original earphones from Plus, the sound quality is much better. It can be said to be excellent.

5. Suggestions: Based on my real experience, I have a few suggestions for improvement.

(1) There are no ear clips to fix the earphone cables, which causes them to sway while running, affecting the run. This is not an issue indoors or while walking, but it does impact running.

(2) The volume adjustment buttons are too hard and require force to press, making it uncomfortable. I wonder if this is just an issue with my particular earphones.

(3) It would be better if the earphones had ear hooks for double fixation.
