I always wanted to buy a portable player to listen to songs and play, but I have been forbearing no way to start. I've been investing a lot in my home business and I haven’t returned to the pressure. I’m afraid to spend money, so I’ve had to focus on the overall situation. Tight belts live. Strictly speaking, I do not belong to the kind of local enthusiasts, but listening to songs is just a need, so I changed the idea, then the price of about a thousand yuan to match it. Compared with in-ear headphones personally like some headphones, for electronic products is definitely to buy new do not buy the old, the headset finally chose the Lumson LasmexL90 closed monitor headphones, the player saw a lot of value in the aunt Friends of the sun original posts, and finally started a Kai Yin N3 lossless music player.
The Kai N3 Lossless Music Player and the Lamson Lasmex L90 Closed Monitor are the latest two new products. Many valued friends have sunk through the single and simply said that they are listening. If they remember correctly, Lumson seems to be still engaged in the forum. Excessive testing activities, of course, these are not the most important, in fact, the main price is relatively cheap in line with my budget, N3 player 1099 yuan, and L90 headset 799 yuan, a total of less than 2,000 yuan, from the recent use of the point of view also meets me The "wood ear" needs.
Kaiyin (CAYIN) N3 portable lossless music player black stone 1099 yuan CAYIN Kaiyin N3 portable lossless music player size is very petite 100mm × 54mm × 13mm, weighs only about 100g, with a USB Type-C interface. The first two types of black and turquoise blue, the official also provided an optional multicolored silicone sleeve. In addition to the N3 line output, the product also supports connection to devices via Bluetooth 4.0 and supports apt-X. CPU part uses X1000 chip, SA25 Jingdong direct links to encyclopedia 
Lumson Lasmex L90 Closed Monitor Headphone Headphone Wired Call Headset HIFI Headphone Gun Color 779 Yuan Jingdong Direct Link In the past, Sony Dafa was used as a tape recorder. Later, I used to use the iPod. The Kaiyin brand was the first contact for me. It was naturally full of curiosity. The rumors from the workshop were that the Kaiyin player was thrust. Larger, and the front of several parameters of the headset is just a matter of high impedance headphones, L90 impedance of 32Ω +15%, so choose a slightly larger player is still a bit more secure. Well, no nonsense, the following into the open box, Kaiyin N3 lossless music player packaging is relatively simple, a white box, open to see more extensive attachments, mainly N3 player, silicone sleeve, Type-C data Line, backup screen film, and product instructions.
On the back of the box, there are more detailed product features and parameters of the player. The DAC decoder chip is AK4490, supports DSD64/128/256-bit decoding, FLAC/WAV/APE lossless music format, and the extended TF card supports up to 256G, supports S/. PDIF Out and USB DAC output functions, positive and negatively inserted Type-C interface, support Bluetooth 4.0. In addition to understanding the Internet, CPU master is the king is X1000, op amp chip is OPA1652+OPA1622, is also the first thousand yuan product support DOP function player.
The player manufacturers have actually attached a film and tear it off, so this is why the front attachment is a backup film, which is equivalent to the new machine comes with two sets of film.
To install an X and paste the logo of Hi-Res, is it a lot of good-looking, and how do I think there are three points like Sony Dafa? The front is a 2.4-inch screen with a resolution of 400 x 360.
The player's size is relatively small, and it is not much larger than the old straight Samsung mobile phone in the home. It is small and lightweight and easy to carry.
In fact, N3's control method is a combination of touch + physical buttons, the middle of the screen is a physical button, left and right are 4 touch buttons, the left side of the fuselage is the physical power / lock screen and volume control buttons, right It is a 3 player play button, and the left and right side control keys are mainly shortcut operation under the lock screen state, and several touch buttons are under the light screen state. In fact, the whole design idea is rather clear, but it seems to be forgotten. Physical keys are designed to prevent accidental touch, especially in pocket pockets.
The back of the player is a piece of veneer, which increases the non-slip effect under one hand and adds some texture.
TF card expansion slot in the right position, the common spring plug, the bottom is the Type-C interface, with the phone in the middle position, the left is the PL / LO jack.
The design of the silicone sleeve is personally liked by me. It can be very good for protection. I don't have to worry about accidentally bumping something. N3 this relatively light player with one hand holding the left and right of the metal frame is inevitably easy to slippery, the back of the cortex can resist how long the summer sweat corrosion is not easy to say, what is the key gap is also easy to enter the gray into the moisture, and more The protection of two silicone sleeves is still very necessary, but I think I feel a lot more grip. Like the physical buttons on the right and left side of the silicone sleeve are completely covered, while the bottom of the PL / LO jack and Type-C interface parts are exposed without shielding and convenient use.
N3's first default firmware is version 1.0, to the official website to download a latest firmware 1.1 brush, brush firmware is also very simple, directly put the file into the TF card root directory into the system settings to select the system upgrade,
Take a look at the N3 player's interactive interface, which is similar to that of a smart phone. The top bar has the current volume, gain range, and current battery level. The volume and power are digital display more intuitive. The middle of the screen is a row of main function options, each option has a text prompt, which is music classification, music library, music player, music settings, Bluetooth, system settings,
Music categories include all songs, favorites, playlists, recent plays, styles, and artists.
If it is the first time to insert a TF card or if there is a change in the card's song, then you can enter the music library to select and update the music library for updating, and you can also select to view and play TF and OTG media content in the directory mode.
The setting options are mainly music settings and system settings. The music settings have 3 levels of gain, and the DSD output modes are D2P and DoP. The other options are almost all. Equalization adjustment, DSD gain compensation, playback gain, PO/ LO output, maximum volume setting and boot volume memory, channel balance can be adjusted,
System settings can choose voice, theme 3 sets of colors, other options are USB mode, vibration, backlight time, backlight brightness, idle shutdown, timing shutdown, restore the factory, I feel worse than a pocket player to prevent accidental touch lock function, Fortunately, the power button is in the left position, and the headphone jack is at the bottom. If you use a silicone sleeve, it's not easy to accidentally touch the screen with a non-strenuous movement.
Kai Yin N3 I personally think Yan value is general, the style is similar to the style of Sony Dafa, touch control buttons and physical buttons are still relatively smooth after the design and control habits, but also more sensitive, basically did not encounter the situation of touch failure Left and right physical buttons on the black screen shortcut is also more convenient, especially one-handed operation. The system's setting options are really rich, and the design of the film and silicone sleeve must be well received. If you can send more than two color covers, then it's perfect.
Then the Lumson Lasmex L90 closed-monitored headphones come out of the box. The box is very large. The magnetic gift box-type clamshell design opens like a book. The back is the parameters of the headphones, 50mm dynamic ring, 32Ω±15% impedance, and sensitivity of 98±3dB. , Headphone weight 380g,
Headphones and all accessories are in a large storage bag, the bag is a hard material, there is a portable handle,
The accessories are mainly the Lamson Lasmex L90 closed monitor earphones, two audio cables and a gold-plated 3.5mm to 6.5mm adapter. One of the audio cables is a remote control cable, which is mainly used for mobile phones. It can adjust the volume and control the music playback. Both lines are metal heads,
The other wire is relatively thick, and there is a fixed design between the 3.5mm plug and the adapter.
The reason why choose L90 is mainly less than 1,000 yuan cheaper, aunt above the original article seems to be not bad word of mouth, and L90 seems no one sun, you can mix the first sun, in addition to the value is not bad, the whole style is a bit classical and modern style Combined style, the outside of the earmuffs black mesh cover and prototype shape is very classical headphones taste, and the rest of the white metal part has a modern earphones, plus the head beam sponge and earmuffs sponge is relatively thick, so that the overall style of the headset looks More full.
From a frontal view, the earmuffs and sponges in the earmuffs, and the sponges in the head and beams are relatively thick.
There is a logo on the top,
Here the design of the earmuffs should be a bit like the inside, although the shape of the earmuffs is a round but the sponge is the oval of the runway, all wrapped ear wear, the texture of the protein skin is also very delicate, the headset is more comfortable to wear the whole,
Headphones adjust the bracket part are metal material, silver and other parts of the black are also more collocation, the outside are marked with the left and right letters, earphone audio cable is plug design, at the bottom of the left channel L position, usually if you change the line More convenient,
Headphone size adjustment on both sides have a clear sense of gear scale, on the whole, L90 headphones are still relatively comfortable to wear, but the headset has some weight, after all, the size of the unit and the use of thick metal sponges placed here, so this headset is more suitable The boy, who is a man's earphone, is less suitable for sister paper than the weight of 380g.
The Bluetooth connection is relatively easy, the direct player enters the Bluetooth open, and the mobile phone opens the Bluetooth, and the search connection is very simple. After all, the N3 is not a WIFI-enabled smart player, so it can't be connected to the Internet. You can enjoy more online free music resources through the mobile phone network, and at the same time ensure the sound quality and thrust. So I personally think that the Bluetooth function is still very important, at least for me. I think I'm more fancy. Occasionally, Bluetooth will use the home speakers. Bluetooth is 4.0 support apt-X compression algorithm, the sound quality is usually able to deal with listening to songs.
Finally, talk about the combination of Keen N3 and Lumson L90. L90 headphones must be down, when the sound of the hand with the machine after a week or the difference is more obvious, great changes. Gain I personally tend to MdB and HdB high-grade, if you need to use the LdB file to open the volume is very large, L90 large-size unit and 32Ω impedance on the player thrust or there are some requirements, with no problem in the high-end comparison Easy, low-grade slightly difficult, the sound field in the high-end next to a little closer, and I personally feel more pleasing to the ear, the three-dimensional feeling stronger. The average MdB mid-range gain volume is enough to be between 50 and 70 depending on the playing song file.
N3+L90's combination of headphones under the three-frequency appears to be more balanced, the tone is more neutral, tough style, with another home Edifier headphones to listen to it will sound a lot warmer, warmer to listen to vocals will appear more comfortable, but It appears that the degree of separation and cleanliness are not as clean as the N3+L90. There are two distinct styles.
50mm dynamic headphones believe that we are more concerned about low-frequency, then let's talk about low-frequency, low-frequency is actually a relatively low-convergence, not fat, it touches more quickly and simply, the dynamic advantages of large-size unit is obvious, low-frequency listening to the "super bass end The "Beyerdynamic rock music" in the album "2" has a great feeling. The metal sense of the instrument is full and the sound field is very enjoyable. In addition, Yan Xuemin's "Drum Poetry" drums did not have a sense of fatness, a sense of coming and going quickly, and the dive depth was slightly weaker. Listening to "Dust Drum" feels that low-frequency dive is more appropriate, there is no sense of drag, nor too heavy sense of low-frequency meat, drum performance more neutral.
IF performance is relatively moderate and full, cold and warm performance in the middle of a point, there is no obvious bias, compared to the sound of warmer headphones, the difference is less some sweet feeling, more neutral and more straightforward. Listening to some of Tsai Chin's songs, I feel that there are few modifications and a sense of originality.
The high-frequency light is transparent and the resolution is normal. Basically, there are no burr feelings when playing pop songs and fever songs. The performance of female voices and metal musical instruments is even better. Listening to Beyonce's “Listen†high-frequency performance is a continuous climax. The vocal is still at the front and the resolution is very clear. Because the headset's overall tone is neutral and there is no warm style of super sweet and sweet sense, so I personally think that this match plays a foreign language song is better than Chinese girls' songs, especially some high-pitched songs vocal defiance and high performance special Clear. If the pursuit of sound quality is to use the player + earphone as directly as possible, I feel that the loss of Bluetooth connection to the mobile phone is still very obvious.
Write here to conclude,
Kaiyin N3 advantages and disadvantages:
N3 player features more, good thrust sound transparent, good value, as if there is blue, I do not know how kind, my black work is still possible, did not find uncomfortable big bug. The volume is relatively light and convenient for portability, as all functions of the price of 1,000 yuan are still relatively complete, especially support for many functions of the DOP so that the gameplay is also more abundant, but also value. The interface is clear and easy to operate. To say the shortcomings, the buttons are plastic and not metal. The player does not have a black screen lock function. Endurance performance is also quite satisfactory, generally full of frequency based on frequency at least one day no problem (always impossible to listen to the song more than a dozen hours a day, if so I did not say). Touch buttons do not have a backlight. At least one option should be designed to let the backlight light up at night and it doesn't matter during the day.
Lumson L90 advantages and disadvantages:
The earphone looks good, the sponge is thick, and the whole ear is comfortable to wear without pressure on the ears. Tri-band equalization is really a monitor style. Headphone turn and adjustment parts are metal shells, with two different audio lines, work well, wire-controlled audio cable can be controlled by mobile phone functions. The sound performance has the dynamic advantage of large size units. Shortcomings or deficiencies are the weight of the headset a little heavy point, boys wearing nothing to wear an estimated heavy feeling, 32Ω impedance is still slightly larger, the thrust of the player may be more difficult, Kaiyin N3 generally need to open to the mid-range gain Caixing.
