When the Chinese New Year was near the Spring Festival, it was a small surprise. I quickly received a shipment worth buying. . . Unpacking: Familiar taste - it's worth it. Simple and atmospheric box The back of the box On the side of the box, scan code to pay attention to the official micro, you can understand the various information of the walker. Open the clamshell box, titanium black headphone body lying quietly, revealing a bit charming sexy. Textured black cardboard sleeves are securely inlaid with earphones and red and black earmuffs. The rounded, somewhat grand feel is the aluminum headphone storage box. Open the storage box, there are charging lines and other sizes of red and black silicone earmuffs, earmuffs have 4 pairs of red and black, reached 8 pairs, really rich, enough to adapt to a variety of different sizes of the ear canal Now. Family portrait Various sizes of adapter earmuffs, there is always one for you. Titanium black cavity, smooth atmosphere. charging Product parameters: CSR Bluetooth chip, support Bluetooth 4.1, Bluetooth 4.1 Needless to say, can make the wireless connection more stable, more clear sound quality. IPX4 level waterproof, this basic resistance to sports sweat. APT-X audio decoding, seemingly more and more Bluetooth headsets have begun to support APT-X, and everyone buys Bluetooth headsets will often look at this parameter. 250H standby, 8H battery life, this parameter to go against the sky. Appearance, manipulation and workmanship The W290BT feels really light, and it's no exaggeration to describe it with nothing, compared to the 13g:22g ratio of JABRA ROX in service. W290BT headphones have smooth, smooth lines and workmanship. The control part is placed on the bottom of the right ear like most Bluetooth headsets. In the official picture, the model misdirects the left and right ears, and I also try to look like it can also be worn steadily. The raised button feels good, pressing The sense of legibility is clear and neat, and the possibility of misoperation can be perfectly avoided. When the headset is operated blindly, each button will have a prompt tone to facilitate identification, which is the necessary humanized setting of the current Bluetooth headset. The wire is a soft wire. After being twisted, it is basically impossible to restore a smooth line. The aesthetic appearance is slightly lacking. However, it seems that the official use of the cord is purposeful, that is, there is basically no stethoscope effect when walking, and the cord is hung on the neck. When the upper wire is in a poor state, individuals still prefer ROX's hard wire, which naturally hangs around the neck but inevitably has a stethoscope effect. Left rox, right W290BT Bluetooth connection For those who have used a Bluetooth headset, you can operate the W290BT smoothly without looking at the manual. Press and hold the small dot button to blink. The phone can immediately search for the W290BT. After normal pairing, you can enjoy music normally. Great meal. W290BT supports connecting two devices, so it is also very smoothly connected to my gear fit2, but found that the device is always the last connection to normal use, connected to the second device after the first device can not connect W290BT For the time being, no reason has been found. Listen to the experience and gently insert the headset into the ear hole. According to your preferences, select a Lin Yinjia's Ain't No Sunshine (Live). Here you need to specify: The essence of the Bluetooth headset based on my mobile phone 320k of mp3 audio, loss or do not expect it. Mobile phone player uses QQ music, simply do not use any sound effects. One voice, very neutral vocal performance, neither cold nor warm, moderate and high pitched balance, bass slightly turbid, dive is not enough, the impression is deeper is the sound field is relatively wide, the resolution of the headset has a good performance, the The details are also expressed, and the technical nature of Bluetooth headsets is considered to be quite good. Another favorite youyouMA - Yo-Yo Ma's Bach Cello Suite No.1 in G Major, BWV 1007-Prelude, the song name is a bit long, not loaded, before listening to UM2 left must listen to the track, personal like the cello The feeling of sound. The cello has a large body, a huge box, and four characteristics of the four pianos. Its loudness, wide and wide sound is its characteristic, and it has certain requirements for the sound field of the headphones. In this repertoire, W290BT has played well the broad advantages of the sound field, showing the gorgeous and touching sound of the cello. Wear performance and endurance Lightweight measure put the W290BT as an in-ear sports earphone, this is not marked on the box of the earphone, the box is written "super comfortable stereo Bluetooth headset". Can sports headphones without ear flaps be worn in the running? Because I was busy during the Spring Festival, I couldn't make a running test. During the period, I was fully charged and went out to audition for two days. Because I was neither ear-hooked nor ear-winged, and occasionally I was not well-balanced, I would turn my headset directly. Tear off, need to adjust the balance on both sides from time to time, because the ultra-lightweight wearing comfort is extremely high, basically no sense of being hung around the neck (this is also buried hidden dangers, later table), if you do not appear to pull the headphones Still wearing a more stable. In terms of endurance, it is mainly used to listen to music to test. According to the number of tracks listened to, it can roughly support 4 hours of continuous listening to music. When it is inconvenient, it will turn off the Bluetooth headset. This is not to hope to save electricity, but because the headset does not have rox. The magnetic switch function is slightly inconvenient. According to the previous tests, there were still problems with the running tests, re-tests, and the inability of the two devices to be perfectly connected. However, because of an unexpected incident, they had to be suspended. Because it lost W290BT. . . One time to go out to eat, the 290 hanging on his neck was nothing but lost. Because the test plan has not yet been completed and I am unwilling to call the restaurant the next day, the front desk MM is very sure that there is such a thing but I need to ask the specific who kept it. I feel sorry for my heart and press the MM request later again. In the past, MM said it could not be found. . . Still not lucky, based on national conditions can only regret. Although regrets, found that W290BT earmuffs can even be compatible with ROX. . . Finally, it is said that you need to write a summary advantage: 1) The material of the earphone is excellent in workmanship, and the lightness of the body material is as comfortable as possible, and the cavity lines are smooth and atmospheric. 2) sound quality is remarkable, good resolving power, wide sound field. 3) The battery life is strong, and the continuous use time can reach 4H or even longer after incomplete test. 4) Simple but easy to use. insufficient: 1) Maybe for individual reasons, it failed to perfectly support the connection of two devices. 2) The headphone cable is too soft, perhaps for the purpose of avoiding the stethoscope effect, but the wire is not completely twisted. 3) Light, it is an advantage, but the headset does not have a magnetic matching function, but also directly led to the loss but no feeling, blame me slightly. The last thing I want to say is that as a domestic manufacturer, Edifier is really a pleasant surprise in headphone. If you re-absorb the various heads of directors in various fields, you will definitely have more progress. Come on! Domestic products should be self-reliant. Maximum bandwidth in the HDMI 2.0 specification is 18Gbps.
