Foreword: The reason for the purchase of Sennheiser started with the purchase of a beats tour 2.0. Because usually there is no high requirement for the sound quality, you can listen to a ring while running. The original friends who purchased beats told me that the quality of the beats was a bit of a problem, because I was cautious about using it and I didn't have any quality problems that my friends said. With the gradual increase in the use of time, beats problems began to gradually appear, first of all, the volume control will be poorly contacted, after the sale to repair the new. The second new volume key presses the volume addition and subtraction to pause, and after sale, the sale gives me a new headset. However, it was the last one that made me really disappointed with the beats. Just after I was given it, the right ear speaker did not ring during normal use, and it was no longer used. There is also no attachment to beats. Also for everyone to buy beats to mention a wake up, after-sales attitude service is no problem but really can not help but the headset has been bad. Sennheiser was a surprise for my girlfriend on the occasion of the Tanabata. Taobao search link directly on the basis of the needs of everyone to choose I think that other versions and the country's price is not the difference between the choice of the State Bank Because it was not at home at the time of delivery, it was already opened. The woman’s ticket tells me that this is true by comparing what it’s worth to buy the god’s authenticity article. The configuration of the headset is finished with everyone talking about the use of headphones: First of all, because I am not a professional headphone appraisal staff or practitioners, the assessment of the headset may not be so correct, welcome everyone to submit their opinions. 1. Since the headset is worn over the ear style, there is no stethoscope effect in the ear. 2. The reference object is tour. For the sound quality, bass does not have beats, but it is also just right. If you listen to the original song, if you listen carefully, the vocals and the instruments inside are very clear and not mixed. For my everyday wear is far enough and exceeds my expectations. 3. It was very inconvenient to carry the headset box so that later it went to Taobao to purchase a new headset package. 4. Two-year warranty, there is no worries about the use of this headset. 5. The earphone cable can be replaced to avoid damage to the earphone. The earphone cable does not feel very solid. But overall, the earplugs gave me more surprises. This is where I missed or said something wrong with IE80. Please also give us more advice.

Unusable tour 
The state of the box after opening 
Because I had to take a piece of rice, I put it in again. "A metal brushed earphone box inside the box just started to feel plastic but it was metal. There are headphones and an accessory silver tray 
The box is particularly good looking, but it is not convenient to carry. 
The four plugs that were not the same at the beginning were forced to be consistent because of obsessive-compulsive disorder. 
Tuner on the back of the box. 
The earphone box is a drawer type magnet attached. 
Headphones are just enough to fit into a sponge-like headphone box, no more or no more, without shaking or rubbing. 
The work of drawing the metal on the headphones feels great, but the wire makes me feel a little unsatisfactory. 
Inside the silver box there are headset instructions, earhook, replaceable earbuds, and clips. 
All accessories at a glance, next to the earhook is to adjust the bass-sized tuning stick, there are other value-friends say no use I think the role is still quite large. A total of 10 pairs of 20 ear plugs (including two pairs of memory sponge plugs) made me feel no matter what the ear is enough.
