Headphone cable review
EB2S line is a non-removable double-strand hybrid oxygen-free copper wire, the workmanship and hardware of the wire are at the qualified line level, and the analysis ability of the double-stranded line is greater than that of the single-strand line in the actual test.
Headset appearance, workmanship description, wearing sense evaluation
EB2S headphones are very exquisite, five-axis CNC processing technology that is not a joke, the actual quality test does not see any burrs and flaws, the painting process is also very good, the cavity is not very large, wearing very comfortable. The cavity is just right to fill the ear hole, so there are almost no serious problems with sound leakage that will occur in many flat plugs, and it is not tired to wear for a long time.
Noise reduction and sound insulation effect evaluation
The physical noise reduction effect of the flat plug in the room is OK, and it belongs to a very general level outdoors, after all, the characteristics of the flat head plug are like this.
Evaluation of technical parameters of headphones
EB25 does not pick the equipment, in the author's actual test, any device can drive the EB25 to produce a high-quality sound.
Tune the main tone
How to say it, the flat head plug is an old technology after all, no matter how to change the cavity and replace the unit, the sound quality level is placed there (cavity structure reason), even if it was the god plug E888. Definitely can't beat the mainstream resin type in-ear headphones now, therefore, the author can only compare from different flat plugs, EB25 in the flat plug is a three-frequency equilibrium, medium frequency warm, the analysis is very good, the sound field is very large flat plug, flat plug can do a large sound field, there is a unique timbre and good analysis, or very strong, EB25 has a good level of hard quality in the flat plug.
Casserole time: more than 200 hours, the headphone performance has been fully boiled
Test cable, headphone cover: original cable + original sponge cover.
Test the device
Bass dyeing, high-fidelity models, MP3 players, mobile phones, computers, desktop ear amplifiers and other equipment comprehensive test of hearing
High Frequency Test Track Sound:
To be honest, the flat head plug can be analyzed out of the background is relatively clean, the knot image is clear, there is a trace of pine fragrance (piano tail, vibrato, overtone) is really good, the overall density of the guzheng sound is better, very pleasing to the ear, the brightness is warm.
Against the cold water "Return to the Garden"
EB25 tone is good, listen to this flute song can be heard, the timbre is more bright, but hindered by the general characteristics of the analysis of the flat head plug, the accompaniment of the instrument analysis is general, can only be said to be very durable, not difficult to hear the sound, but from the high resolution, high quality separation, the flat head plug This aspect is really difficult for it.
Mid-range test track listening
Vocal tuning has always been NICHEK's strong point, and sure enough, the EB25's vocal performance is also true
The vocals are in the right position, not behind, not close to the ear, the density of the knot is normal, not thick, not thin, not cold, almost no tooth tone, the voice is delicate and emotional, can express the singer's emotional ups and downs, fluctuations and other infectious forces, but hindered by the cavity of the flat head plug and the factors of the vocal environment, the tail noise of the female voice is still a little bit, not the sound quality level of the monitor-level vocals, but this is a flat plug, can be made into such a vocal, really good, anyway, the author is surprised.
Male vocals: Tao Zhe, "Her Song"
Unlike the female voice, the EB25 male vocal density is slightly larger, or the same problem, the male vocal has a trace of noise at the end, but overall the vocal is still very delicate and warm, very attractive, and the vocal is in the right position.
Low frequency test track listening
Saweetie《Best Friend》
The low-frequency instruments of this song are numerous and complex
EB25's performance in this song can be said to be able to beat most of the flat head plug, each low-frequency instrument has a certain degree of separation, each different low-frequency instrument sense of volume, elasticity is also OK, there should be some diving also.
Transient, low-frequency dive test songs
The EB25's transients are doing well, with easy retracting and lower potential in a variety of different flat plugs.
Sound field, resolution, and resolution test songs:
Cheng Chi "Lou Lan of Life and Death"
The soundstage of the EB25 is the biggest surprise that the author thinks, the horizontal depth is wide, and the flat head plug inside the soundstage that the author encountered is very large. The sound field spatial positioning, separation and analysis of the overall instrument also belong to the hard quality of the flat head plug, which has a certain degree of resolution and separation, and is very good.
Tri-frequency comprehensive test hearing summary:
In general, EB25 is still a flat plug full of surprises, although it is also warm and pastey (all kinds of flat plug characteristics, even if it is the same as the thousand yuan level), but EB25 on this basis using a variety of new technologies and units, the overall analysis, three-frequency separation, low frequency, vocals have been greatly improved, after all, it is the product of the integration of new technologies, it is completely full of surprises and the product of the value of the ticket price, in the style is also more omnivorous, any track can be solved in this regard is still good, Looking forward to the next generation of NIKECK flat head plug.
Suitable for songs: Omnivorous any track
