appearance
black celluloid has good texture, excellent workmanship and smooth hand feeling. It is a beryllium-plated single-moving coil. The internal moving coil unit can be clearly seen on the back. The wire and waterproof storage box are all handed down from Feiao's ancestors. Three pairs of balanced sleeves (black), three pairs of low-frequency sleeves (black and red) and one pair of sponge sleeves are sent.





sound
Driving conditions:
- impedance 32ohm sensitivity 109db/mw converted to 124db/vrms
- The bottom noise level of about 0.6uv is required to drive to 0db.
- Drive to 10db bottom noise requires about 2.0uv bottom noise level (10db bottom noise is exactly audible when the sound source has no bottom noise)
- front-end output impedance is preferably below 4ohm
- is a plug that can be pushed well.

objective test:
TOTLAB B & K 4195>>TOTLAB iepe>> ASUS u7 mark ii with a range of 100-8000Hz.

The left-right channel deviation is within 0.5db, and the consistency is excellent.
subjective hearing:Compared with the same price of Tiantian T2plus, based on the original S number, the audition is detailed:
Evaluation Related 17 Agree with 2 Review Articles
Low frequency:is too much, more than that of t2plus every day. The dive is average, and the strength is not bad. It is stronger than t2plus. It has some residual noises. It is faster to collect, a little hard, solid and clean.
IF:human voice is more prominent, closer than t2plus, with some staining, slightly thicker, and sounds more ear-catching, with a little grainy and dental sound.
high frequency:is slightly brighter, the permeability is average, the line feeling is strong, and it is relatively sharp. Some high-pitched instruments (such as drums and violins) are more prominent (should be caused by 8kpeak). It is not the soft high-frequency style of t2plus, but a high-frequency style with partial brightness and some ears grasping. Such high-frequency is slightly exciting and a little dry.
Other:sound field is not bad, slightly inferior to t2plus, mainly concentrated in the horizontal direction, the overall balance is warm, with some dyeing, the musical instrument is denser and closer than t2plus, the positioning is more accurate, and the back amplification is a little paste, thanks to the beryllium plating diaphragm, the transient is excellent.
summary
fd1 is the moving circle with the lowest price of Feiao. Even so, it still maintains Feiao's high standard of workmanship, appearance and accessories. t2plus with the same price is a soft and balanced earphone. Compared with t2plus, you can feel that fd1 has obvious ear-catching sound dye, which is more suitable for playing back some pop music with sense than t2plus, combined with very low driving conditions, it is more suitable for beginners and pop music lovers.
Recommended Index:7.5/10

its high frequency may be a little exciting for some people, it can be improved by using angel Jimmy high frequency set.
Feiao also has a 0.78mm balance line ls-2.5a from 98 yuan, which has a high cost performance. Students who need balance can start with it.
