LeTV announced on the afternoon of April 20 that the Le 2 Series mobile phone announced the cancellation of the 3.5mm headphone jack and replaced it with the CDLA standard (Continual Digital Lossless Audio) proposed by LeTV. The headset has an independent lossless music codec, trying to create music beyond HIFI. Experience. This "imitation iphone7 in advance" approach, grabbed Apple's rice bowl, played the idea of ​​digital streaming media. Regardless of the wrestle of the parties behind us, we only talked about the cancellation of the headset hole. We found that Sony Dafa had a strong sense of enthusiasm in this revolution. They had released a number of Bluetooth headsets (mostly sound quality) before LeTV and Apple. Lossless); my new arrival of this Sony MDR-EX750AP cable plug is clear evidence, because it also recently launched a Bluetooth version of the MDR-EX750BT plug, had to admit that the two hands are ready to play very pretty.
The packaging of the Sony MDR-EX750AP is actually worthwhile, because Sony has always been very conservative in its packaging style. It has always been the same, with a box or girdle outside, and a layer of hard inside. Paper box.
On the back of the package, there is a simple emphasis on the plug unit and the wire control. The small in-ear size is simple but not simple. A 9mm drive unit is wrapped in the streamlined profile, and a sufficient distance between the drive unit and the sound tube is ensured to achieve high Resolution sound quality experience, seamless minimalist design is to let the small size burst out of the core elements of sound quality.
Sure enough, as I expected, there is a box, the color of the box shows the color of the headset, it is learned that Sony MDR-EX750AP launched a total of yellow, red, green, black, red five colors for users to choose. My non-blue non-green in my hand, abbreviation grass blue (laughing, commemorative? Or I have color blindness).
It took a little thought on the fixing of the headphones, and it had a metal clip to fix it. The two headphone units are like two hip flasks with sleek gangs.
Sony MDR-EX750AP standard accessories are not too many, four pairs of different sizes of silicone earmuffs (SS, S, M, L), a headphone cable length regulator (wound up to 50CM) and A carrying bag.
As a portable device, the headset bag is very necessary, Sony MDR-EX750AP headset bag to get rid of the traditional closure of the rope, took a new magnetic suction seal, it is also more convenient and simple.
The clear sound quality comes from these two aluminum “bottle gourdsâ€. The high-rigidity aluminum cavity can smoothly transmit low-frequency and clear mid-high frequencies and suppress vibrations, reproducing high-quality sounds. We will talk about it later. Sound quality features. You can use it to hear sound quality much higher than that of a CD, the buzz of pop music, the pulsating jazz rhythm, the drumming of rock and roll, and the use of advanced sound quality techniques to pamper your ears.
Headphone cable adopts advanced silver-plated OFC (oxygen-free copper) material, which can reduce the loss in signal transmission and increase the high frequency, presenting crystal-clear treble. As a portable device, the SONY MDR-EX750AP headphone cable has a jagged, wear-resistant design that is durable, while reducing the worries of winding, more robust, more durable, and easier to use. In addition, Sony MDR-EX750AP is equipped with a one-touch mobile phone remote control, fully compatible with iPhone, Android, BlackBerry mobile phones, support for hands-free calling and switch songs, but does not support adjusting the volume, which brings some inconvenience.
Not only does the 3.5mm headphone jack feature a pull-resistant T-shaped plug, but it also enhances protection on the headphone unit. The anti-pull protection mat wraps around the outlet for a short distance.
The official recommendation I use Dafa NW-A25 player with the Sony MDR-EX750AP to use, to see how honest I am, to the fever to this point, Dafa let me dry I will do. The last time I listened to SONY NWZ-A15+XBA-A2, the partner's impression was deep, the original sound was reproduced, and the hierarchy was clear.
The feel of the Sony NW-A25+MDR-EX750AP is generally satisfactory. If it is based on value theory, most people in the same price range will still choose Dafa's equipment. The voice is very natural, clear and unrefined. The "female wife" added a bit of dullness, and the "girls" added a bit of embarrassment. In short, it gave me a very pleasing, natural and refreshing charm.
I listened to Long Meizi's "You Are the Happiness I Want". This song is one of the best songs on the coolbox list. The sound of the instrument before the tune is a bit mean, giving people a clear, comfortable feeling until the voice is heard. After that, there was “level†and “distance†with the sound of the instrument, and it was felt that the vocal power was more important, and naturally it was on the front. IF (human voice) is exquisite, natural and remarkable, especially for females such as Longmeizi. The rhythm of the drums and cymbals brought by the accompanying accompaniment is good, although the treble (or high frequency) given by the instrument is not prominent and not bright, but it is enough to hold on to the character that is not disappointing. For a plug, this is enough.
Then he listened to He Yihang's "Whoever gave love to pain," and the male voice is also good. I bet if there is a feeling of drinking a cup of boiled water if you use the flat plug on your mobile phone or mobile phone to listen to the song. , Heartache + upset, why is this? Details are not enough, musical instruments, accompaniment, men's tears mixed, people are extremely annoying! Although they are all in line with the heartfelt mood of “what love has given to the pain†(haha, laugh again), this pain is a “perverted†heartache. Change it to NW-A25+MDR-EX750AP and listen to it. The taste of authentic “heartache†comes, and the levels and details are rich. After the separation of instrumental sound, accompaniment, and man’s tear, it’s not annoying. It hurts (because I heard the emotion). The song has a special feature. You can hear men and women singing and you will realize more about the performance of vocals.
Summary: Three-band equalization, low-frequency is not disappointed or unassuming, high-frequency is not outstanding and does not give up, be rated as a superb student with excellent overall quality, more resistant to hearing is its place. The low, medium and high frequency bands have a good separation, especially the emphasis on vocals, making it more forward, and the performance of the instrument is more focused on the level of some, guitar, piano, violin and drums give me a sense of distance and A sense of shock can be felt. NW-A25+MDR-EX750AP is still OK in the density and resolving power of IF. However, once it receives a non-HiFi mobile phone, it will feel insufficient. The details of the phone use is not very rich, perhaps this is also the official recommendation NW- The reason why A25+MDR-EX750AP works seamlessly matches is called a dedicated package for listening to pop music. IPhone, vivo, OPPO and other mobile phone HiFi plugs are not to be missed.
