I just bought the Sony MDR XB500 headphones, and I want to find out how to burn this machine. I like

Sony has used its unique technological advantages and innovations to create the best Bluetooth noise-cancelling headphones on the market. Not one of them. For a long time, when it comes to noise-cancelling headphones, people naturally think of Bose.

A few months ago, all of them** rated the QC35 as the best noise-cancelling wireless headphones on the market. The Sony MDR-XB550A launched by Sony this time has a huge advantage over Bose QC35 that cannot be ignored, and people have to admit that Bose has been left far behind by its opponents.

1. Touch control.

Wireless headphones use touch to perform operations such as volume and song change is nothing new, Philips' mentally retarded SHB7110 adopted this design hundreds of years ago, and Samsung also released one two years ago. But in general, there are not many headphones on the market that have this characteristic.

Touch control has a lot of advantages over buttons, just raise your hand and swipe it, and the operation is very smooth. And it doesn't have to be done with your hands, and it can be easily controlled with other parts of the body (such as feet). Traditional push-button operation requires a finger to press with a certain amount of force, and another finger needs to be held in the opposite direction to fix the earphone, which is not convenient in many cases.

2. Quick Attention Mode

Press and hold the right earcup with the palm of your hand (or the handsome gesture of touching with two fingers that is common in movies) to turn on the Quick Attention mode (the quick reminder mode translated by Sony China is too much). In this mode**, the volume will be turned very low, and the microphone will pick up the outside sound and play it back inside the headphones, even more clearly than if you had taken them off directly.

When listening to a song, having to stop** or even take off the headphones because you need to talk to others can't be more annoying, and this feature perfectly saves the experience of wearing headphones when you go out.

3. Ambient sound mode

Compared to the Bose QC35, which can't turn off noise cancellation when Bluetooth, Sony thoughtfully provides 4 modes, which are controlled by two buttons on the headphones. In this way, when you go out, you can listen to ** with headphones and talk to friends at the same time, which is quite convenient. And in noisy environments such as subways, using ambient sound voice mode will also be clearer than directly taking off the headphones to talk233MDR-1000XThere are only three buttons on the 233MDR-1000X, two are used for mode switching, click the power button will inform the power through voice, and press and hold to turn on and off to enter Bluetooth pairing mode.

The three buttons have protrusions of different lengths, and it is easy to tell which button you are touching during blind operation.

4. Industry-leading noise reduction effect.

5. LDAC & APTX support.

The bass is intensified, the treble is muddy, but it seems to be quite electronic, and it is not easy to harsh. It's quite classical, it's more ugly.

These headphones are enough to watch movies, but listening to songs is not cost-effective at this price, I just happened to have one. The advantage is that it has a beautiful appearance, is comfortable to wear, and is quite light. The disadvantage is that the sound is not transparent enough, the bass is quantity but not of high quality, and the vocals are a mess, and the treble is forgotten.

There are too many options within 400, JVC HA500 is good, not expensive, Edifier H840 is OK, and Qinyin's XMETAL Bluetooth headset is also OK, which can be wired by Bluetooth.

The Sony Headset MDR-XB550AP is the same as the Sony Headset MDR-XB450AP, focusing on the volume improvement of low frequencies. Since both are the same in the choice of driver unit and diaphragm, the actual sound effect will be relatively close. As an entry-level headset, most manufacturers will pay attention to the improvement of low frequency, because in the three frequencies, the low frequency increase is the easiest to feel, and most manufacturers just improve the volume of low frequency, Sony headset MDR-XB550AP is an overall improvement in low frequency, although the low frequency volume will not be too large, but the dive is deep enough and elastic.

How to cook headphones:

1. First of all, the full frequency is opened, the purpose is to open up the headphones, the method is to use a variety of different frequencies to continuously **, generally continue to boil for one to two hours and then take a break, but the volume is not too large, there will be obvious effects after about ten hours. The bass performance of the original headphones has also been significantly enhanced at this stage, but because of the limitations of my sound card Shizhou Han, the signal of the pot headphones I made can only be up to 11025 Hz, but it is definitely enough, the sound that adults can hear has a vibration frequency range of about 20-20000 Hz, the sound wave with a frequency lower than 20Hz is called infrasound, and the one above 20000Hz is called ultrasound, and infrasound and ultrasonic are an inaudible sound wave. But I had an experience of trying out these audio signals at a friend's house (using a big speaker) at the beginning to play those frequencies that most people can't hear, to see if any of them had golden ears, but then my friend's child (about 4-5 years old) ran out of the room and shouted something so ugly, so that it proved that children have better ears than adults.

Note that it is best not to listen to the signal of the headphones, as it will be uncomfortable. )

2. What you need to do is to make a sense of boiling ** (especially high-quality headphones will be of great help), most of them use some high-quality audio vast pure ** sounds, personal favorites, sad cities, happy hotels, etc., the use method is the same as above. At this stage, if you listen to too many pop songs, you can also change the flavor and listen to these pure **, which will give people a very comfortable feeling.

3. At this time, you can choose your favorite music**, and you can play it more fully in **this genre**. In fact, after the earphones are used for a long time without boiling, the sound quality will also be improved to a certain extent. However, it has never been able to open up the Qijing Baimai and boil out the ** feeling, and the sound quality has not been fully exerted, so I said that the old headphones should also be cooked, but the effect is big and small.

Precautions for cooking headphones:

1.When burning the machine, pay attention to it, if you are not sure whether the volume is too loud, find someone to help you listen, if you can't hold on the headphones for 10 seconds (non-preference reasons), then the volume is too loud.

CD1: 5min white noise, 1min glass smashing, 30min violin, piano concerto, 2min 80-25khz sweep, 5min white noise, 3min Apollo 13 takeoff, 2min 80-25khz sweep, 10min symphony, 5min white noise, 10min big drum.

CD2: 15min pink noise, 15min 20-20kHz sweep, 5min kick drum, 15min white noise, 5min sweep, 5min kick drum, 15min symphony.

The parameters of the XB500 are as follows:

Product Type: Dynamic headphones.

Wearing style: Over-the-head.

Rated power: 1500MW

Frequency response range: 4-24000Hz

Product impedance: 40 ohms.

Sensitivity: 104db

Unit diameter: 40mm

Empirically speaking, it is definitely possible to push, but it is estimated that it will be very difficult.

The volume may have to be turned on above 70%, and it may not work well.

With an impedance of 40 ohms and a sensitivity of 104dB, the XB500 should be quite difficult to push.

My experience comes from the XB700, although the XB700 unit is larger, but the impedance is only 24 ohms, the sensitivity is 106DB, I have this headphone, from the parameter point of view, it must be better than the XB500 push, but I use iAudio 7 and E30 and other flash *** push is just like that, the volume should be turned on to a large level, and it is not so laborious to push with IPC.

In addition, Sony's *** has always had a small thrust, and the B152F is only an entry-level ***, so the reasoning knows that it naturally can't be pushed very well.

Therefore, it is not recommended to match it like this, if it is B15F, it is best to push the earbuds with low impedance to be more appropriate, I hope to choose carefully.

Tell you, it's absolutely no problem to push the XB500, although the impedance 40 looks high, but the rated power is less than half of the XB1000, I tried both headphones with the Sony B162F, and the result is that the 40 ohm XB500 is significantly better than the 24 ohm XB1000.

The B series may not be able to push well, you can try the A series and E series.
