There is a kind of beauty. She is deeply buried in the corridor of the time tunnel, lying quietly, not being disturbed by the disturbances of the world. Since the awakening of human agility, she has existed as an understander and guardian. In the human world, there are countless kinds of ways to listen to the entanglement of love and hate, the epiphany of life and death. In suffering, she is the voice of the sad Matthew, the peace of the peace of the Lord, calmly leading All living beings reach the other side of love and purity with firm conviction; in joy, she is the touching voice of the sound of nature, the joy of the heart of holiness and enthusiasm, and the secret of the incomprehensible depth of the human soul in the way of love. She is music, the carrier of good things and things, love, the love of the living world and the human soul.

I do not know when, the author fell in love with burning ears, remember that the first earplug is a flat plug of Sennheiser, forget the specific model, she is external, not refined, not perfect, but she let me The memory is profound. Under her mediocre externality, the hidden is actually a kind of rich and gentle and comfortable listening style. The music is like a stream in the stream, it is a kind of elegant walking in the clouds, she surprised me inadvertently. And the dying of life. So, this plug is a kind of beautiful life for me at the time.

The flowers are easy to see, and the beautiful things are easy to disappear. The plug is less than a year old, and I donâ€™t know where I lost my life. I have never seen it. This time I chose to encounter "her"-k420.

The story starts here AKG K420 Listening Sharing

The beauty of the same thing is not because of a little bit of her face, but also because of her superficial design, but because of the exquisite workmanship of her work, people find the comfort of a trace of aristocrats in the rigor, and this The K420, a noble gray that is respected by Germany, has such a high-end and quiet temperament. AKG K420, a well-known manufacturer of Vienna headphones, loves technology, AKG Love Technology is the most well-known audio field in Austria. One of the brands, but also one of the world's four major headset manufacturers.

And this K420 won the 2009 Red Dot Design Award! K420, one of the classical fairy-like small ears of Austria in the music country, compared with the portability of the previous K4 series, her new elegant casual design brings people a The new visual impact, like inadvertently rushing into the wings of the human leisure world, with everyone to integrate with music, taste high quality of life, thus raising the price of a grade price.

What's interesting is that her semi-open headphone design, like to avoid the outside world can not hear the wonderful music when the headphones are playing, this fun and not afraid of disturbed design makes people can't help but have this headset just like having a Friends, she is happy to share, so that you are very hard to forget. Of course, her intimacy is also her new unique 3D-Axis? folding design, more portable, comfortable to wear, intimate contact, you are more willing to bring this A kind of music elf goes elegantly in this world. Well, she is intimate and not outdated, comes with a headset carrying bag, she can be compatible with any model of IPHONE, it is also an inevitable music surprise in the current fashion life, not to avoid the age Boundary is a medium for people to understand the soul of music. Maybe, one day, you even want to use her to resonate with life.

Why can we use her to convey the slang we love, the cry of life, because of her super linear sound, and the very attractive and full of sound, even at high volume can eliminate distortion, this music feast due to the transmission of K420 The majestic and inspiring symphony of the Life Opera has repeatedly impacted the bottom line of people's minds, angered in the contradictions, and swears the final effort to fill the gaps in life.

"California Hotel": The ear regularly echoes the rhythm of the guitar, through the linear sense of headphones, the guitar sound in the song shows the "sticky" and sometimes the dim light taste. Then the drum sounds knocked up, deep, wide But very secluded, because the dive is not deep enough, the drum sound will feel a little rough when you hear the end. The prelude has been beautiful, the clarity of the applause highlighted by the earphones echoed the ear, Don henley opened Sound, the problem is coming. She didn't clearly distinguish the vocals from the instrument. It can't highlight the unique voice of don henley. The vocals and instruments are all crowded together, making henley's already hoarse voice become more vicissitudes. "! But no disappointment, K420's gentle and clear sense of hearing shows the sense of helplessness of the California hotel. Sometimes, the author will feel distressed, suspecting that this K420 is a living thing, afraid of missing a beautiful.

"Quizas Quizas Quizas": K420 may be more suitable for the symphony of the symphony, the song singularly spread Nat King Cole's affectionate love and hesitant entanglement, the drumming of the sense of law, the deep heart is hard to refuse Singing, like Nat King Cole's love for the "unacceptable, difficult to refuse", the author's entanglement with the heart and spirit of the K420 is "difficult to be baptized, unforgettable", K420 super linear magnetic music wind performance deep feeling.

"Jambalaaya": The ethereal and graceful naughty tone floats in the air. In K420, the soul singing of Ono Lisa is like the fairy music from the sky, and the K420 is the fairy flute, the fairy piano, in the background. The guitar sound that Ono Lisa is good at is a kind of ethereal and clear beauty. It also proves that the transmission of the linear magnetic music tone of the K420 earphone can convey the affection, and can accurately grasp the low frequency and the dive. The fairy tales that can float in the sky, the full sound, and the innocent whisper, created the legend of K420.

Prelude, main song, climax, a whole piece of music drifting, the author found the beauty of K420 in the pursuit of a beautiful journey. No surprise, the beauty of K420 lies in: heritage, calm, generous, intellectual, affectionate, fairy. K420 Good, even if it is not extraordinary, not empty and literary, can not be integrated into everyone's heart, but we also want to thank K420 for her unique beauty, K420 beauty should not be an end point for everyone, but should be Another beautiful starting point! It is the starting point for people to chase after the good and seek high quality. It is the echo of the mysterious music art in the jungle of the world. Just like every person who chases the beautiful, the author continues to pursue this one from K420. Music means that the way of the navigation light is close to freedom, close to the beautiful, close to music, and I will also remember the medium of music that I am moved by. - This is a dream of music. After the dream wakes up, it will not be The end of the crowd.
