Good value for money and average quality.

Ear hooks, there is no good choice for Xinqing limbs, there is a good ear hook called C60 in the Zhengzhi Dayin Branch, you can go and see it.
However, after slipping, you pick the low-frequency gain +3 for the equalizer, and then adjust it to see if it can satisfy you.
-
It might be better to turn the equalizer to rock....Personally, I feel that Heisener's headphones are good....But don't buy a fake...Heisener's bass is fantastic....

It is not recommended to buy for the following reasons:
The tilt angle of the nozzle is less than 35 degrees, which is not suitable for Asians to wear unsteadily, while Europeans and Americans have a wide ear canal and can be completely stable.
The sound quality is average, and the vocals are clear but not very layered.
With a 60mA battery, you can listen to songs for up to 5 hours and talk for 4 hours.
Meizu EP51, or Beats Power2 is recommended
-
You can listen with headphones, as long as there is a headphone jack or a place designed to plug in headphones, you can listen with headphones.
-
No, the headphone jack is for you to connect your phone or other devices as a wired speaker.

Budget? The difference between the expensive and the cheap ** headphones is too big. I've used the Edifier W280BT (about 150 yuan or so).

The manual went to ask the seller directly! You can't ask for instructions here.
Bluetooth headset pairing method:
The Bluetooth headset is powered off first, then press the power button until the red and blue lights flash each other, and then tap to pair on the phone.
Bluetooth headset has no sound:
After connecting, you should check the call settings and audio settings in the Bluetooth settings, so that you can play ** and listen to songs! If there is no sound, there is no check in the Bluetooth settings!
Bluetooth headphones are factory reset like this: follow the steps below:
The first step is to keep the Bluetooth headset on state. At this time, the indicator light is blue or red and blue alternately on.
Step 2: Plug in the charging cable and start charging.
The third step, at this time, you see that the indicator light has changed from the original "blue light on or red and blue alternately on" to a solid red light, that is to say, forced charging, causing the Bluetooth headset to directly change the indicator state, at this time, continue to charge for 2 minutes, the fourth step, at this time unplug the charging cable, you can test the Bluetooth headset has been restored to factory settings.
Note, although this method is a passive factory reset, it will not damage the Bluetooth headset, please rest assured!

The "pot" of the earphone is actually in the pot diaphragm fold ring, the new headphone diaphragm fold ring mechanical compliance is poor, resulting in a relatively large distortion, after a period of use, the compliance gradually improves, and the distortion will gradually drop to a normal level. For the headphone amplifier, as long as it is not turned off, it is burned, but for headphones, a certain power signal must also be fed to make the diaphragm vibrate constantly. New cars, machines, etc., before normal use, have to go through a stage called "running-in", so that the internal mechanical devices are fully coordinated and coordinated, and enter the best state in advance.
Similarly, the push unit of the headset (the speaker inside the headphone) is also a mechanical device, to be precise, it should be a semi-mechanical, semi-electronic combination, mainly composed of a voice coil, a diaphragm, a positioning ring (a metal ring that holds the diaphragm in place), etc. The mechanical part belongs to the paralytic system and consists of the diaphragm and the voice coil fixed to the diaphragm. A compliant element can be equivalent to a capacitance in an electronic component, where the capacitor stores electrical energy and the diaphragm and voice coil store kinetic energy.
The size of the headphone unit is equivalent to the parallel value of the two capacitors, the diaphragm and the voice coil, which is the key to determining the quality of the sound. The material used in the diaphragm and voice coil is a high-compliance material, and its internal molecular structure is unstable in the early stage of finalization, so the compliance size is also unstable. After a long period of movement, the distance between the molecules is lengthened, the uniform distribution of the compliance is increased a lot, and the overall compliance of the speaker is also increased a lot, and the most important value of the speaker is the lowest resonant frequency, which is professionally called f0, which basically determines the lowest frequency that the speaker can achieve, and it depends on the equivalent quality and equivalent compliance of the speaker, because the speaker is a mechanical resonance system equivalent to a resonance circuit on a circuit. The frequency of the resonant circuit depends on the inductance (speaker equivalent mass) and the size of the capacitance, the size of the fo and the inductance are inversely proportional to the size of the capacitor, so the greater the speaker compliance, the lower the f0 of the speaker, and the better the low frequency dive.
The change of compliance leads to the overall situation, and all the mechanical data of the speaker as a whole will change, such as the mechanical quality factor of the speaker, and the greater the compliance is equal to the increase of mechanical loss, so the mechanical quality factor will become lower, which is equivalent to the sound sounding softer.

Hello! ASUS's ROG Popularity GO gaming headset is a high-end gaming headset, and the gaming experience is very good, so buy it without losing money!
Original headphones: The sound quality has been improved, the most important thing is with in-line control function. >>>More
It can't even compare to half of the sound quality of MX500, there is basically no bass, the midrange is very thin, the treble is still lively, listening to ** is not good at all, the workmanship is good, it looks very high-grade, and it is not high-grade to use.
