The price of these three in-ears is relatively close, so it is very suitable for comparison with the sense of hearing. Cool than F1 is a friend to buy a machine to send random. LE01 believes that everyone has heard about it, and there are quite a few online reviews. As for the Sennheiser CX250, you should listen less. I heard that this earphone is an upgraded version of the previous CX299. These two models do not seem to be listed in China. The online products are all known as factory goods. It is true or false. I don’t know, of course, the one that the younger brother got is also the factory goods. After all, these models are more unpopular. In terms of personal opinion, there should be no fakes. Of course, I can’t guarantee it. Among them, F1 is just recently arrived, but it has also passed, and the other two have been in hand for a long time. The following is the topic.

In-ear trilogy cool than F1

Appearance: The wire is very soft and feels good. The latter part of the earplug cavity is not metal, but is coated with a layer of metal-like material. This material should be easily lacquered after a long time. The cylindrical plastic at the end of the cavity is too strong to feel the grade. In fact, before I got F1, I hated it very much, because the ear I used to wear felt that my ears were very uncomfortable. I always felt crowded, and the sound was easy to get bored. The hearing was easy to fatigue, which made people very uncomfortable. However, the medium earmuffs supplied with the F1 seem to be specially tailored for the ear holes of my size, and they are very comfortable to wear (so the other two earplugs I put on the pair of earmuffs to listen to, because to compare Hearing, so I have to take it off from this pair of earplugs and put on another pair of earplugs. I am really afraid of being broken, huh, huh), I can’t feel the presence of earplugs in my ears, and then I tried the trumpet and The large earmuffs feel the same comfort. It seems that the earmuffs are good, so the wearing feel is quite good. However, the sound insulation effect of this earplug is a little worse. It can still be heard when the outside sound is louder, but it also has some advantages, that is, it is safer and the sound will not be stuffy. In the past, the stethoscope effect that existed on many ears was no longer present on F1. This should be the reason why the wire material is better.

Hearing: F1 itself has some sound dyeing. It seems that this earplug not only draws on the appearance of Sony, but also has a taste of Sony on the tuning. But the sound is not too heavy, the earplugs are warmer, I really like this sound.

In terms of low frequency, this is a kind of earplug with both quality and quantity. The dive is not deep, but I feel that it is just in place, the low frequency is full of elasticity, and there is no such rumbling feeling because of having sufficient low frequency. But the low frequency hardness is not enough, it feels a bit soft (soft, not scattered), but this softness gives a good sense of envelopment. I think this should be the deliberate action of Coolby's tuner, because this earplug claims to use biofilm, I heard that the biofilm can not be too shocked, can not afford. Therefore, the low frequency of F1 is sufficient, but it is very soft and should be deliberately designed to protect the biofilm.

In terms of vocals, F1 also has a good performance in terms of vocals. The vocal performance is in place. It can restore the essence of the singer. The vocals are a little bit behind, not obvious, but the vocals are still very Sharp, listening to the human voice is still quite comfortable, but the roundness is not enough. The tri-band separation is very good, and there is no vocal sound because of sufficient low frequency, so the transparency is not bad.

On the high frequency side, I feel that the weakness of F1 is at a high frequency. Of course, it is not a very weak one. It is said that the weakness is not extended, and the extension is not high enough, resulting in no feeling of being arrogant when listening to high-pitched songs. It doesn't hurt, it doesn't hurt. When expressing a violin-like instrument, when the rhythm of the violin is fast, it does not reflect the aggressive feeling.

In terms of sound field, the sound field is performing well in both vertical and horizontal directions. The sound field width is ranked second among the three earplugs. The sound field feels great, but the atmosphere is not felt. This is lost to LE01, which will be mentioned later.

In summary, the vocal and low-frequency performance is quite good, the transparency is very good, the high-frequency is still under-ignited, and the sound has a burr and tooth sound when it is opened. If the appearance and packaging of the appearance are improved on the basis of improving the sound, it is really worth the money for the earphones that are currently positioned more than 200.

In-ear trilogy of the Sennheiser CX250

Appearance: In terms of materials, workmanship and appearance, the CX250 truly reflects the style of the big brand, which is beyond the reach of F1 and LE01. The front half of the cavity and the duct are made of piano lacquer, and the latter half of the matte process feels very high. The earplug also has a volume adjuster, but the personal feeling is not practical and not easy to use. The elasticity and toughness of the earplug line are full. But this line also brings a little bad thing is that the stethoscope effect is too heavy, can not swing the line or touch the line when listening to music, otherwise it is really depressed. It is not enough to wear F1 and LE01, and it is OK to put on the middle set of F1.

The CX250 gives me the worst overall feel in these three earbuds. And it is also the most difficult to push, it is normal to open a sound that is twice as big as the other two. The high frequency is very sharp. In the performance of the fast-paced violin, it can really restore the sharpness, giving people a feeling of aggressiveness, making people feel a little breathless, because they follow the rhythm, let People are straightforward. The vocals are also very comfortable, very clear, very real, better than F1, and level with LE01. The amount is not big, but the elasticity is very good. The music that listens to the movement is not as shocking as the F1 and LE01. It takes the light route and is still the upper body of Senhai.

The sound field is the most uncomfortable place for my earplugs. The sound field is too narrow. It is much narrower than F1 and LE01. It feels very dull and unbearable. It is very easy to be tired, so I rarely use this earplug when listening to songs. F1 and LE01 are much more atmospheric than CX250. This earplug is more suitable for listening to human voices and pure music with no low frequency. Listening to dynamic music is simply a crime. But the sound field is too narrow, making it unbearable and not suitable for long periods of time.

In-ear trilogy LE01

Appearance: Appearance For LE01, it is really a disadvantage in these three models, there is no advantage. I remember when I first bought the LE01, I opened the package and saw the look of 01. I felt that the appearance and materials were really very cottage. It was not like selling more than 200 earplugs, but when I put it on it, I really felt it. Surprised by its voice, it is no wonder that it is so popular in Hong Kong. The wearing feeling is also good, the stethoscope effect is not very obvious. The wire is the hardest of the three, but it is also not elastic.

If compared with F1, the earplugs are cold. The overall feeling is quite good, the sound is very transparent, the tri-band separation is also very good, listening to songs is very comfortable. The sound field is a little smaller than the cool F1. The LE01 sound field is not only big, but also the music is very strong. The sense of the scene is very strong. It is really comfortable to listen to the song, especially when listening to the big music. 01 low frequency is also a kind of quality and quantity, the amount is not as big as F1, but the low frequency hardness and firmness are better than F1. The vocals are very sharp, very clear, and very prominent, a bit high, the suspicion of the low-frequency head, the vocal performance is better than the F1 and CX250. The high frequency is slightly lower than the CX250 in ductility, but slightly better than F1. The same can not be a good expression of the violin's aggressive feeling, but at least that smell.

Overall, the LE01 is the most balanced among the three models. The performance of each frequency band is excellent, the high frequency extension is good, the vocals are clear, the low frequency is strong, the sound permeability is very good, and the sound field is wide enough.

Written in the end: These three earplugs together contrast the sense of hearing, can be more realistic and highlight their respective characteristics. This is more than the sound of a single paragraph, the truth of the general discussion there, let you more realistic experience of the level and positioning of the various earplugs.
