In October of last year, I wrote a Beats solo3 Wireless evaluation report, and in about the beginning of November, I changed hands at a price of 1,200 yuan. At that time, the lowest price recommended by the mother was 1,599 yuan. At the beginning, it was 2299 yuan, and the beats really dropped.

Prior to this, I also bought a Sony NW-A25. The reason why I did not buy the HN version was that she was shy. So for the noise-reducing headphones that have been in the water for a long time.

The outer packaging of the EX750NA is covered with a thin film to indicate that the product has not been opened yet can also be dust-proof.
▼ When tearing off the film, you must pay attention to the warranty card on the back. After you retain a good warranty card to enjoy the post-sale service of the Bank of China, you don’t really understand Dafa’s considerations and how good it is in the box. Should this user accidentally lose it, Go to trash.
â–¼ After tearing off the film, let's take a look at the design of the package and print the product sample on the front.
â–¼ can be used for smart phone hands-free calling feature.
â–¼ The top is hanging loop
â–¼ Label with production information at the bottom.
â–¼ The side is the basic information and accessories for the headset.
â–¼ The back is a detailed explanation of active noise reduction technology.
â–¼Bottom to turn on the headset
â–¼ After opening, see also multi-layer packaging.
â–¼ Finally, remove the inner package from the bottom.
â–¼ The inner package opens from the side.
â–¼The EX750NA is lying quietly on the bottom of the box.
â–¼ Headphones are fixed on the wire.
â–¼ The headphone cable is embedded in the side sponge tab.
â–¼ Lift the top of the headphones and place various accessories underneath.
â–¼ The accessories are divided into two layers. The upper layer is mainly the storage bag and the charging cable, and the lower one is the manual and warranty card.
The EX750NA is equipped with a standard aircraft plug converter. After all, the active noise canceling headphones are often used for commuting and traveling. For the aircraft's noise-making tools, the converter is indispensable.
â–¼ The charging line is quite satisfactory, Microusb interface.
The storage bag that comes with the EX750NA is very exquisite workmanship, with a magnet at the top, you can quickly stretch and gather.
(1) Warranty card
(2) Instruction Manual
(3) Silicone earmuffs + earphone clips
The EX750NA provides four additional earbuds, enough to meet the needs of people of different sizes.
â–¼ Because the battery box is too heavy, there is a situation where the ear plug is pulled when it is worn alone. A clip is very necessary.
The EX750NA cable differs from the conventional headphone cable in that the surface is not smooth, but has a strip of texture. This design can increase the friction between the wires and prevent the headphone cable from being tangled together.
â–¼ Because the EX750NA involves active noise reduction, the design of the switch is essential. There is a power indicator above the switch. The long indicator light indicates that the active noise reduction is on. When it is flashing, it indicates the power. When it flashes, it indicates that the current power is 75%-100%. Three times indicates that the current power is 50%-75%, and two times indicates that the current power is 25%-50%. , 1 shows that the current battery is less than 25%.
The back of the switch is the microphone and the remote control. The remote control can only control the pause and play of the song (click), cut the song (double click) and so on.
Three, headphone plug
â–¼EX750NA headphone plug
Fourth, the battery box
â–¼ Because the function of the MDR-EX750NA is more complicated, the battery box is much more structural and heavy.
â–¼ The bottom of the battery compartment can be opened for charging.
The interface of Microusb makes it compatible with many data lines, but due to the different current and voltage, in order to protect the battery's long-term work, the original data line is still the most secure choice.
Five, earplugs
The earplugs of the EX750NA are relatively finely crafted, but the gaps at the joints are still relatively obvious.
▼ Materials, the bottom is plastic, the top is metal, earmuffs are silicone. SONY Logo on one side and “L†and “R†on the other side
â–¼ The back of the earbud is the identification hole for active noise reduction. The earphone recognizes the noise situation through the back and bottom holes and intelligently selects the noise reduction mode.
â–¼ Silicone earmuffs soft texture, red outside the white, the official way to take the earmuffs is to take off the rotation, do not recommend the following figure this way, so I only show.
â–¼After removing the silicone earmuffs, there is still a layer of sponge in the sounding part, unlike other in-ear headphones, which are directly a layer of metal mesh. Deafness is relatively easy to accumulate in this area, a layer of sponge can alleviate this problem.
â–¼ The concave ring design allows the silicone earmuffs to be securely attached to the earbuds so that they do not fall off easily due to pulling.
Six, beam line
â–¼ The cable harness is a standard accessory for headphones. You can tie the cable at both ends to a certain position to prevent the headphones from shaking. Use the picture below.
â–¼ Specific Usage: Originally wanted to draw a picture of himself, who knows to find this masterpiece of soul painter and vividly posted it here.
Seven, with NW-A25 1. Bundle state
I chose the red section specifically to complement my big red NW-A25. The combination of the two is unsurprising and perfect.
â–¼ If the bundle status is perfect, the stretch status will be a bit pitiful. Since the EX750NA has both a switch wire control and a battery box, the overall size is too large.
â–¼ At the bottom of the corner plug plus a thief heavy battery box, it seems a little discordant, may be more appropriate right-angled plug.
[Active noise reduction function]
The active noise reduction effect of the MDR-EX750NA is nothing to say. After it is turned on, the whole world is quiet. It is a covert, but the loud noises around it are indeed greatly reduced. The MDR-EX750NA will actively choose the intensity of noise reduction according to the ambient noise. (There are three modes), especially in the canteens and trains.
The best and the coolest is in the kind of poor quality bus environment. The background sound is mixed with the rumbling sound of the car, the buzzing of the body parts, the noisy words of the surrounding people, and the whistle of other cars on the road. Feeling everything in the surroundings, after putting on the noise-reducing headphones, listening to Jacky Cheung's platinum collection and gold collection, it was a state in which the people were noisy and alone. Close the glasses, in addition to the bumpy seats, it is difficult to find that this is a public transportation off peak hours, more like a pickup truck swinging in the country road.
ã€Defects of noise reduction】: Headphones with active noise reduction, especially at the mid-to-low end, have obvious problems with noise at the bottom. The bottom noise of the EX750NA does exist, but in the noisy environment where the sound is turned on and the song is played after the noise reduction function is turned on, this noise is almost undetectable. In addition, when using the EX750NA while riding, you will feel obvious wind noise. This problem is relatively prominent. Even if there is music playing, the wind is still more pronounced.

2. Sound source
â–¼ are basically lossless sound sources, California hotels and ferry two close to the master level.
Second, actually hear
Since the EX750NA has significant differences in sound quality when noise reduction is turned on and noise reduction is turned off, in order to present the best sound quality performance, the actual listening process is divided into closed and open noise reduction.
1. Triple frequency comparison
The triple frequency of the EX750NA I tend to intermediate frequency> high frequency> low frequency. The prologue in Ferry was relatively boring, and the female voice of “One I love†was not too toxic. Instead, “The Girl of Dabancheng†and “California Hotel†won my heart and could express the special charm of male voice.
2. Sound field changes
The EX750NA has undergone tremendous changes after the noise reduction is turned off and on, especially the sound field. When it is turned off, the music is boring and the sense of hierarchy is not strong. After noise reduction was turned on, the entire music was widened, and the distant echo made people feel as if they were in a larger listening environment. Did the feeling of “Drums of the Drums†after the opening of the noise be changed from a small music classroom to a performance hall?
3. Resolving power
I used the EX750NA to listen to the preparation of the symphony-water music overture (string music). The overall feeling is that after noise reduction is turned on, the sound field is wide, the resolution is improved, and various strings are intertwined and can also be Differentiate between similarities and differences.
ã€to sum up】:After all, the evaluation of sound quality is a matter of metaphysics, but after the noise reduction of the EX750NA was turned on, there was a noticeable improvement in all aspects. If you have to price the sound quality of the EX750NA, if you want to put aside noise reduction, I personally think that it is in the range of 300-400 yuan. After all, the EX750NA is a headphone with a noise reduction function. If it is too harsh on the sound quality, it is not 700 yuan.
(1) The headphones are exquisitely crafted with solid materials and rich accessories, covering 3 pairs of earplugs and a protective cover.
(2) The earphone's wire design is delicate, it is not easy to knot, and the bend can also be returned quickly.
(3) The active noise reduction function of the headset is very powerful. The three types of noise reduction modes are very humanized.
(4) When the noise reduction function is turned on after the headphone is turned on, the sound quality is significantly improved.
(5) The headset's long life is enough to cope with multi-day commuting needs.
2. The disadvantage
(1) The design of the headset was too complicated, the remote control and the battery compartment were divided into two parts, which led to the trouble of storage and added weight.
(2) The headphone's active noise reduction function still has a noise floor, and it is also obvious that the wind noise is too much when riding.
(3) In terms of sound quality performance, the three frequencies are not sufficiently balanced, both the low frequency and the high frequency are weak, and the female voice is not sufficiently toxic.
(4) Charge the headset longer
Second, improvement suggestions
1. In the next-generation in-ear noise canceling earphones, the battery part and the remote control part are combined into one and even one ear plug can be considered.
2. Further improve the active noise reduction function to reduce the effects of noise and wind noise.
3. The sound quality expects more optimization and adjustment, after all, 700 yuan headset has entered the ranks of light burn.
4. Can consider adding fast-impact function, product prices can also be relatively increased, after all, compared with the price of QC20 there is still a certain room for improvement.
Third, the evaluation conclusion Wikipedia
BOSE QuietComfort 20 (QC20) Active Noise Cancelling Earphones Best Noise Reduction In Ear Earbuds 557 Reviews14 Original 12 Good 55 Direct Links View Details My topic is "I did not expect that you are such a noise reduction headset" refers to the EX750NA price is only one-third of the QC20 still has a powerful noise reduction function, three kinds of noise reduction mode automatic recognition and activation, it is really cost-effective , At the same time relatively good sound quality performance and Dafa quality guarantees are a lot of points for this headset.
At the same time, there is no such noise-reducing earphone as the EX750NA. The design of the remote control and battery box is slightly different, lacks beauty, and sound quality is good but not enough to burn. So I think the next-generation Dafa's in-ear active noise canceling headphones still have huge improvements. Space, I'm willing to give it a chance, or look forward to the mother gave me a chance to experience the effect of head-mounted active noise canceling headphones - MDR-1000X.
