The mobile phone is now a standard for manpower and above, and then the mobile phone accessories: headphones, but also along with the increase in sales

Although the headset naturally comes with honey "HIFI" attribute, but for most consumers, the headset is a sound-absorbing, easy to carry, comfortable to wear accessories, can not hear, do not need any sound quality, not to carefully Feel what analytic, what transient, what sound field

Before the headset is used 3.5mm interface, but with the release of the iphone 7, canceled the 3.5mm interface on the Apple mobile phone, we do not discuss the purpose and advantages and disadvantages of doing so, just say that this will make Bluetooth headset Better to sell

However, due to the convenience of wearing (no line trouble), Bluetooth headsets sometimes have sports attributes, but due to the diversity and complexity of sports (who knows what sports you are doing), sports headphones are in motion. The first thing that needs to be ensured is that it does not fall off. What's next is what is waterproof, sound quality, and a bunch of heart rate detection functions.

Rambler, a veteran audio brand, has a variety of glorious histories in the field of audio. He mentioned that Ramblers will all think of his audio, used more or less, or seen it. However, Rambler is not only associated with this, but also in the field of headphones. Frequent force, big headed flagship, small in-ear phone plug, he has involved

What I received today is Edifier's Wireless In-Ear Headphones. Look at the old stereo brand. Under the complicated usage scenario of sports, what kind of answer will be given. At the price of RMB 300, what kind of choice will be made?

â–¼ Big New Year's mailing, it also SF fly, SF praise!

▼Tear the courier bag and see a cluster of foam that is tightly tied up by the mysterious “value” tape.

â–¼ The side of the gap can see Edifier's brand LOGO

â–¼ After you break the seal, you can see the front cover of the headset. The above is the hook, brand LOGO, the middle of the huge product color printing, the following is the model and information

â–¼Headphone name is called: Ultra-comfortable stereo Bluetooth headset, model is W290BT, the following four tags in turn represent Bluetooth, microphone, 10m maximum connection distance and support APTX codec technology. The most obvious feeling of this APTX technology is that the delay is small. Before using car Bluetooth, Bluetooth audio to listen to WeChat voice is always delayed, resulting in endless listening or inaudible, with this Bluetooth headset, 1s voice can easily listen to complete

Apt-X is a digital audio compression algorithm based on sub-band ADPCM (SB-ADPCM) technology. The original algorithm was proposed by Dr. Stephen Smyth in the 1980s. Developed by Audio Processing Technology (now merged with CSR) and named apt-X. Originally used in professional audio and broadcasting. In recent years, apt-x in the Bluetooth wireless audio transmission field has greatly replaced the SBC (Sub-band Coding) due to its low latency, good fault tolerance, and high sound quality. Currently available in the apt-x family are aptX Bluetooth, aptX Enhanced, aptX Live (launched in 2007), and aptX Lossless (launched in 2009). apt-X has the following features:

Required bandwidth: 10Hz to 22.5 kHz, 56kbit/s to 576 kbit/s (16 bit 7.5 kHz mono to 24-bit, 22.5kHz stereo)

â–¼ side is the brand and model

â–¼Back is the introduction of colors and various parameters, the color I received is pale gold and white

â–¼ detailed parameters, Bluetooth 4.1, battery life 8 hours, charge 2 hours

â–¼ There is a two-dimensional code on the other side. This two-dimensional code is not an app, but the Edifier's WeChat public number.

â–¼The earphone is a side-opening design, magnet adsorption, strength can also be reversed will not open, after opening the lid there is a layer of matte plastic cover, it is very beautiful

â–¼ Open the frosted plastic cover, you can see the headset, four pairs of headphones and a storage box

â–¼ The top layer of foam lifts up, there is a layer below

â–¼All contents, manual, warranty card, Bluetooth headset, earphone cover, storage box

â–¼There are two packs of earphones in the storage box, there is a charging cable, the earphones in the storage box are all super small

â–¼ The charging line interface is Micro USB

â–¼ The top of the storage box is not cushioning sponge, but a preparation material, texture clear

▼The color of the storage box is a kind of gray-green feeling. It has a cold touch and a faint brushed feeling on the surface. There is a line on the back that reads “A Passion For Sound”.

â–¼The front is the LOGO of the walker. The opening way of the storage box is to open from the side

Although there is no content in the manual, but this instruction has to be seen

â–¼ Headphones do not use a separate design on the left and right units on the tall, but the left and right unit cord connection

â–¼On the headset line, it is also indicated that only the 5V adapter can be used for charging, but cannot be charged with the fast charging charger. Could it be said that when the headset is charged, D+D- and the signal will cause a wrong handshake?

â–¼ light white gold cavities, electroplating cavity is very bright, female ticket said this feeling is called "Bulingbuling" feeling, the unit has a ambler in the middle of the LOGO

When I flipped over, I noticed that the feeling of “Bulingbuling” was not a whole. Fortunately, the gap between the dividing lines was small, but this design should be considered for wearing comfort. The electroplating touch is not very good, especially After shedding

â–¼ in-ear design, look at the direction of the catheter tilt, it should be the lower outlet

â–¼ The earphone's catheter is not long, it is very comfortable to wear, there is no QJ feeling, but this earmuffs is loose

â–¼A strainer prevents foreign matter from entering

▼ There is a small ring at the position of the unit. There is an “L” on the ring. It does not touch any inexplicable bulge.

â–¼ But the right unit is offline

â–¼Wire control, there are two arrows, an origin, feedback is very unclear, there is a light in the middle, bright blue and red

â–¼The back is the MIC hole

â–¼Dust plugs with a lightning sign on the side

â–¼ After opening, you can see the charging port

â–¼charging effect

â–¼ Press and hold the dot to power on, then try to connect one plus three phones

â–¼Turn on Bluetooth and you will see Edifier W290BT. Click to connect

Try changing apples

â–¼Apple can check the power, this is still very reliable. In addition, this switching connection device is also very fast and easy to use.

â–¼ unit cavity can also be, is not small, can be very comfortable to wear, that is, this earmuffs is relatively loose, easy to remove when wearing or carrying, remote control whether it is placed in front or behind, feel all In general, the effect of the stethoscope is obvious

â–¼ After the hand is reached, there is no charge, and 50% of the volume is used for about 7 hours before the power is turned off automatically. Then, the charge current is about 0.1A. Therefore, there may be compatibility problems with some mobile power sources. Charging takes 2h2min, is still relatively fast

â–¼ The call response is very sensitive, the call effect is clear, the line control is very clear whether it is placed in front or behind, but no noise reduction function, noisy environment, all noise will be recorded

To be honest, the sound quality of this Bluetooth headset is still very good, soundproofing is good, tri-band equalization, the sound field is relatively large, parsing in general, vocals are not posted nor far away, low volume is relatively large. Quietly listening to the song, the headset's voice is also worth 300, in addition to the interpretation of the point of difference. However, during the exercise, it will ring

â–¼ As a main sports Bluetooth headset to say the last sport. First of all, it is said that wearing, daily mild exercise, walking, fitness, cycling and the like is not a problem, that is, after turning a little bigger, it will be loose, you need to choose a slightly tight earmuffs, but the tight earmuffs After a long time, it will support the ear, this is more embarrassing, if there is a kind of professional sports earmuffs, to prevent the rotation of the earmuffs, you can effectively avoid this situation. Then I said that listening to music is comfortable. Although it sounds like it is heard after exercise, the stethoscope effect of this headset is simply too serious. Not only does this in-ear design have a stethoscope effect, but the cord is also placed on the front. , or on the back will collide with the clothes friction, all kinds of sound will rush into the ear, the tri-band equalizer in silence is gone

Aside from selling all kinds of rhetoric, it's all about rogues. The first thing to be sure is that this headset is a highly finished product at a price of RMB 300.

Bluetooth 4.1, support APTX technology, responsive, small delay, also supports switching two devices, continuous listening to music for 8 hours no pressure, charging 2 hours to full, tri-band equalization, loud field, clear calls, very beautiful storage Box, these are very good points, and the price is competitive at $300.

The consistency of the pale gold-white cavity is too bad, and the shiny electroplated and pale white plastics are severely cracked, which is very worrying about the lifetime of the electroplated appearance; the remote-controlled key feels very poorly, without wearing headphones, It is difficult to distinguish whether it has been pressed simply by the feel of the hand; during the movement, the movement of the headset will cause the headset to rotate, resulting in loosening or even falling off; the stethoscope effect is very serious, if it can provide a professional sports headset headset cover will feel effective to solve this problem, It is this cavity that may need to be redesigned.

thank you all!
