Since the original telecom giant Ericsson cited the AWEI Bluetooth headset in 1995, the Bluetooth headset has become an indispensable accessory for business people and sports enthusiasts. How to choose a Bluetooth headset that suits you needs to look for it according to your own needs. This article is to let us find the fun to share with our loved ones through a true wireless Bluetooth headset.

Before the beginning of this article, I would like to introduce you a concept, the true wireless Bluetooth headset:

The biggest difference between a true wireless Bluetooth headset and a traditional Bluetooth headset is that it uses the Multiplexlink multi-point wireless interconnection technology. As a new wireless Bluetooth headset, it realizes wireless connection between left and right ears. This kind of earphone completely abandons the wire connection outside, and the left and right earplugs can work independently, so the hands-free call can be mastered. When you need to change to dual channel stereo, open another earplug, and close it to automatically form a dual channel stereo mode. When sharing music, you will not be hindered by the wire, and it is more convenient to use.

  Body Start

The engineer uncle sent us a Roman Q5 Bluetooth headset from the Internet.

There are many things after opening! Headphones, headphone caps, data cables, storage bags and instructions.

Everyone came to watch the new Bluetooth headset.

Is this earphone still for one person? What about the others?

My father said, "Only by sharing can we be happy with our loved ones."

Dad came to talk about the Bluetooth headset: "This is the Roman Q5 Bluetooth headset, which is characterized by a dual ear true wireless Bluetooth headset. The headset works through the MFB one button. This work includes power on, power off, answering the phone, hanging up the phone, and replaying the phone. Under the MFB button, there is an LED light with different colors corresponding to different states."

Press and hold the MFB key to start the machine and continue to press and hold, the LED light will turn purple, which is the pairing state.

The LED lights flash alternately red and blue, indicating that the pairing is completed and can be used normally.

There is a white charging port cover on the top of the headset to prevent accidental dust or water stains from seeping into it.

The earplug part and the main body of the headset form an L-shaped structure, and the head of the earplug is made of white plastic material to form the filter screen of the Bluetooth headset. The main function of the filter screen is to adjust the sound pressure and frequency band, just like the headwear and earplug front screen.

There are L R words on the bottom of the headset according to the left and right ears, and the microphone is at the bottom. Both the left and right ears have microphones. This design can greatly increase the effect of the microphone on the sound. There is also a small hole at the connection of the L-shaped structure of the headset, which is mainly used to help regulate the sound pressure.

This is the headphone cap. There is no special bayonet on the headphone, which means that the headphone can be rotated 360 ° at will.

The headphone cap is installed on the headphone, and the effect is shown in the figure above. In addition, the cover of the charging port is also opened in the figure above. It can be seen that the charging port uses the standard Mirco USB interface.

The data cable is like this. One to two can charge two headphones at the same time. After the introduction of the basic information, let's have a test.

Actual test

Hello, everyone. The name of Xiaobian is Happy. The following tests are completed by this editor. The main tests are Bluetooth connection test, sound effect test, battery test and other tests 。

1. Bluetooth connection test

In the link of Bluetooth connection test, I tested three operating systems: Android, iOS and WP. Android and iOS systems can be connected normally, and WP system cannot scan Q5 devices.

For the dual connection test of Bluetooth headset, SONY and Meilan mobile phones are used. During the test, the left headset can be connected to two mobile phones at the same time, and voice answering can be performed according to the actual situation. After the left and right headphones are connected together, only one mobile phone can be connected normally. According to the voice prompt of the headset, when the phone 1 is connected, the left headset indicates that it is connected; When connecting mobile phone 2, the left headset indicates that the second device is successfully connected, which means that the left and right headphones cannot be paired and connected. When only the mobile phone 1 is connected, pair the right headset, and the second device is also successfully connected. The headset will also prompt the left channel and the right channel, so it can be judged that the left headset can be connected to two devices at the same time, but the second device can only be the mobile phone 2 or the right headset.

  2. Sound effect test

Cai Qin's "Ferry" was selected as the low frequency test of Q5; In general, listening to bass is based on the principle of not scattering and not boring. The Q5 has enough low frequency diving, and the sound is slightly tight, but it is basically enough as a non professional music headset.

Use Chen Baiqiang's "Just Like You" to test the high frequency performance of the headset. The high pitch of Q5 is not harsh and performs well.

Suzanne Vega's Tom's Diner is a very clean song with a pure voice to the end, which can test the performance of the mid-range voice. Q5 also performs well in the mid-range voice, with little clear sense of hierarchy.

  3. Battery test

During the battery test, use the USB smart interface of NetEase small box to quickly charge the 50mAh battery. After about 45 minutes, the headset is charged. During use, after listening to music for 3 hours and 5 minutes continuously, the left headset prompts that the battery is low, please charge. This reflects a problem. The power consumption of the left and right earphones is different. As the main earphones, the left earphones consume power faster than the right earphones. Recharging the right earphones also means that the right earphones fill up first, and the LED light turns blue.

  4. Other tests

This test includes wearing experience and MFB button status test. The wearing effect of the left and right ear colleagues can be seen in the figure above, or two people can wear it separately; The song will be played after wearing it. The barrier free distance between the two people is about 10 meters. The music can be heard normally. If the music is stuck at 12 meters, the device will be disconnected at 15 meters or 8 meters with obstacles. Normal running and jumping during wearing will not cause the Q5 to fall accidentally. The MFB button has completed the task perfectly in terms of testing the startup, shutdown, pairing, answering, and replay of the phone.

  Summary:

The Roman Q5 true wireless Bluetooth headset has completed the task well in the headset evaluation process. The stereo sound effect is high and the IF performance is rarely good; One key operation of MFB button is simple and labor-saving; The battery cruise capability is generally 3 hours of music playing to meet the needs of commuting and daily sports; The Bluetooth connection is stable, and the switching process between connected dual devices is normal; The voice prompt is up to standard, and there are corresponding announcements regardless of the status.

  Suggestions for improvement: 1. Since the left and right earphones can be divided into main earphones and auxiliary earphones, it is recommended to increase the battery capacity of the left earphones (main earphones) to ensure that the cruise time of the left and right earphones is basically the same. 2. When calling, you can refer to the mobile phone address book to broadcast the name. 3. If the charging cable can be transformed into a charging headphone box, it can be charged at any time when going out. I think the Q5 is perfect.

Again, the earphones that we need to know how to share and how to share with our loved ones are good earphones. I wish everyone happy.
