Adjust yourself and feel the power of “male poison†— DENON Tianlong C820 In-ear Headphones
The work has been very fatigued recently. She indulges in her daily work and is unable to extricate himself. Every day at work, he arrives at 9:00. When he arrives at home, he always finds some songs to listen to and relieves himself of his own state. He has bought a sallow, a very bright plug. Too stimulating, listening to the hair rose more to listen to the "uplift", can not wash away my fatigue, after going to the headphones shop continuous audition, hearing is believing, finally found this plug, one can adjust my own State of the plug, Tianlong C820.
[Kabben official store] Denon/Dragon AHC820 AH-C820 Earbud in-ear hifi headphones 1180 yuan Lynx Select direct link C820 is Tianlong's new flagship earplug, and it is also the 50th anniversary of the model. It has special meaning. However, on the packaging, no special "value sense" was felt. It was a bit small disappointment. It's ugly and it's called Jane. Let's look at it.
Window design is a bit new
Withdraw the box, the accessories are also very simple, storage bag, several pairs of sleeves, instructions.
Some other accessories
Plug out, I feel the C820 headset is still a little sincere feeling, the headset is positive, black and white color, the front of the cavity is metal, there is a certain degree of laser gloss, not heavy.
The line of earplugs is also a little odd and odd, two-line arrangement, with a unit for each line (Dragon C820 is a dual-unit design), obsessive-compulsive disorder under the grip, although the line is relatively thick but soft enough.
The appearance is finished, talk about the most important part of the sound, what is an ear plug used? Some people may say that nonsense is of course listening to music. Actually, I would like to say that it is used to regulate one's own state and use the beauty of music to convey to oneself and adjust one's own state. This is the ultimate goal of listening to music.
Listen to music at night like to lie in bed, close your eyes, plug in Tianlong C820, I like to have a fluffy red and blue covers, wearing a very comfortable, will not fall.
Song selection generally opens Netease Cloud, according to their own state to select their own music, there is no fixed song, this I have to say that Netease Cloud is really intimate.
Just point one, it is the first foreigner's song, all in English, I do not understand its lyrics, but this is not important, the music I think consists of three parts: rhythm, melody, timbre; these three parts, I can feel that music is OK.
The sound of the initial guitar sounds, the speed is not uniform, and the rhythm is very close to the ear. “Wow!†sounds like a male voice. The voice is clear and clear. There is no obvious staining, and the singer’s saliva can be heard.
About half a minute, the singer's speaking speed became faster, and the speed of other drums accompanied by the instruments increased. The bouncing texture of the low frequency also increased. At this time, there was no confusion. The singer's voice followed the instrument. The rhythm of the walk, the tone will also increase. Listening to the heart is very comfortable and dynamic, and there is no previous feeling of stimulation.
There was nothing dyed in this song, the saliva song, the speed of rhythm changed obviously, and the melody was very simple. Although I couldn't understand the lyrics, I could hear it very well and the purpose was achieved.
The reason why sound will have these performances is also inseparable from its hardware design. C820 dual unit design, 11.5MM unit, this size is relatively large in the dynamic earplug, so that the dynamic area of ​​the vibration will also increase. In addition, the impedance is only 16 ohms, and the sensitivity is 115 DB/MW. It can be seen that it is very easy to drive the ear plugs. Even if the mobile phone has little thrust, it can push a 7788.
Disadvantages:
Someone will ask if this earplug is perfect? I will answer, it also has disadvantages,
(1) It is a two-line design. This design cannot be changed and loses the fun of changing lines.
(2) In terms of listening to a violin piano instrument, it has a glossy feel, but it is not bright enough at high frequencies. It is definitely not an instrumental musical instrument. Its instrumental performance can only be suitable for accompaniment and is more suitable for pop music. .
to sum up:
Finally, if you like to listen to male voices and like to listen to rhythm-rich songs (Europe and American pop, Chinese pop), Denon C820 can give it a try. I believe its dynamic will give you a feeling that you can enjoy music. Beauty, find a state that suits you.
Electric dc motors were the first type widely used, since they could be powered from existing direct-current lighting power distribution systems. A electric Dc Motor's speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings. Small electric dc motor are used in tools, toys, and appliances. The universal motor can operate on direct current but is a lightweight motor used for portable power tools and appliances. Larger electric dc motor are used in propulsion of electric vehicles, elevator and hoists, or in drives for steel rolling mills.
Areas of application: the electric dc motor rotor part of the armature iron core, armature, commutator, such as equipment, electric dc motor is suitable for most electronic products, such as electric screwdriver, laser, smart home, gas valve, etc
Applications:
Method of use: the best stable in horizontal plane, installed on theelectric dc motor output shaft parts, cannot use a hammer to knock, knock prone to press into the electric dc motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
Electric dc motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a electric dc motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
Electric dc motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
