Blue Blues 2 supports in-ear detection. In the process of playing music and video with headphones, take off headphones to automatically pause audio, and put on headphones to automatically resume playing.

For the specific operation and personalization settings of Charm Blue Blus 2, users can adjust them in Lifeme's exclusive App. For example, in the shortcut operation section, users can manually customize the touch and long press functions of the left and right ears. The left and right earphones are independent of each other, and there is no main and auxiliary earphones. After personalized adjustment, Charm Blue Blus 2 supports up to four different shortcut operations.

In the actual experience process, the touch feedback from Charm Blue Blus 2 is very sensitive. No matter it is three-click or long-press, the operation prompt tone will pop up instantly after the operation is over, because the operation time required for three-click and long-press is longer than that for single-click and double-click, so it is not easy to produce false touch in daily use. In Lifeme App, users can also upgrade their headphones OTA by upgrading the headset firmware feature, so as to get a better experience in time.

Meilan Blus 2 supports game mode, which has lower latency than music mode. With Bluetooth 5.2 protocol low latency dual transmission technology, the lowest latency of headphones can be reduced to 50 ms.

Noise reduction full-scene dynamic ANC intelligent noise reduction, is the charm blue Blus 2 brought this new function. In the noise reduction process, two independent microphones at the front and rear of the earphone body respectively collect the noise phase difference value between the outside world and the ear canal, and then phase reverse compensation is performed through the noise reduction chip AI calculation, so as to cancel the noise transmitted into the ear canal from the outside world. Blue Blues 2 noise reduction depth to 42dB.

Charm Blue Blus 2 has three separate levels of noise reduction mode, namely mild noise reduction, balanced noise reduction and deep noise reduction. Different noise reduction efforts can be provided for users according to their needs.

In the headphone noise reduction test, CTOnews.com selected two daily scenes: office and subway. The noisy office is the scene where I spend the longest time every day. When you listen quietly in the office, there are air conditioners, footsteps, keyboards, conversations, sudden cell phone rings, and even the squeak of seat twists. Although everyone at work tried to avoid making noise, all kinds of sounds intertwined, making the whole office far from quiet. First of all, we turned on mild noise reduction in the office. The moment we turned on the noise reduction mode, the air-conditioning sound that was running all the time disappeared, and the seat squeak was isolated from the headphones. Although the keyboard sound of other colleagues could still be heard, the ambient sound was obviously reduced a lot. If we play music or white noise in headphones, the sound in the office will be suppressed a little.

After switching the Charm Blue Bluus 2 noise reduction mode to deep noise reduction in the office, the ambient sound is further reduced. In deep noise reduction mode, even if music or white noise is not played in headphones, ambient sound will not interfere too much with hearing, but simple deep noise reduction cannot block high-decibel sounds such as cell phone ringtones. If you want absolute noise-free. You still need to play music or white noise in your headphones.

Although the office is the place where I stay the longest every day, in fact, the subway when commuting to work is the main position where I listen to music every day. Because I live and work halfway across town, I commute more than two hours a day on the subway. The noise level on the subway is much higher than that in the office. Subway electricity, stop announcements, conversations, even crying children and chatter.

After turning on the headphones in the subway for mild noise reduction, you can obviously feel that the ambient noise is reduced by one level, but if you don't play any audio in the headphones, mild noise reduction can only reduce the ambient noise, and it can't produce too much noise suppression. To be completely immersed in your own world, the song volume needs to be turned on at 3/5.

After converting mild noise reduction to deep noise reduction in the subway, the ambient noise drops again by one level, but if you want to completely suppress the noise, you still need music as an aid. However, in Deep Noise Reduction mode, the audio volume only needs to be turned on at 1/3-1/2 to completely suppress ambient noise. This volume is also more friendly to ear health. Compared with mild noise reduction or noise-free listening mode, deep noise reduction can exchange lower song volume for quiet ears.

The following video is the recording of Charm Blue Bluus 2 radio in subway and office scenes. Because the sound quality will be compressed to a certain extent during the radio acquisition process, it does not represent the real sound quality. It is only for comparison reference. It is recommended to wear headphones during watching the video.

In addition to ANC intelligent noise reduction, Charm Blue Blus 2 also supports two-way four-microphone ENC call noise reduction technology. Through hardware enhancement, compared with single microphone noise reduction of TWS headphones of the same category, it can filter the ambient sound more thoroughly during the call, and the dual microphone array equipped on both left and right ears greatly improves the accuracy of sound collection during the call. From the actual effect, when I use Charm Blue Blus 2 to talk to the other party in the subway, the noise on the other side of the phone will be greatly reduced, and the words in the call can be accurately recognized, neither the words will be missed nor the noise will cover the voice.

Sound quality Charm Blue Blus 2 adopts a new generation of customized 12mm frequency super-dynamic ring, softer TPU suspension edge, combined with bio-fiber frequency composite diaphragm, to help achieve more flexible high, medium and low frequency frequency response capability. The 12mm sound unit provides more bass detail than the 6mm and 10mm sound units commonly available on the market. In terms of frequency response range, Charm Blue Blus 2 is 20 Hz-20000 Hz, which perfectly covers the hearing range of human ears.

From the perspective of music experience, the medium and high frequency of Charm Blue Blus 2 is especially prominent, and the voice of the instrument is clear and bright; the timbre is warm but not stiff, with a certain sense of presence; the resolution is high enough, and the boundary between the voice and the instrument is clear, so that it will not be pasted into a piece. The Blue Lotus 2 has such a high performance in this price range that I am quite surprised.

In Lifeme App, users can also change EQ schemes to adjust audio output in various bands. The App presets pop, rock, classical and vocal schemes.

In terms of battery life and charging life, in normal mode of headphones, one-ear battery life is 6.5 hours, and 24 hours of battery life can be provided with earphone compartment. When the headset is in noise reduction mode, the one-ear battery life is 4.5 hours, and the total battery life is 18 hours.

After actual testing, listening to songs for 90 minutes in noise reduction mode, the left and right headphones were powered down by 30%.

Headphone battery capacity 45mAh, headset case battery capacity 400mAh. In terms of charging, Charm Blue Blus 2 supports wireless charging. Wireless charging is rare for headphones at this price point.

Summary Charm Blue Blus 2 inherits the high cost performance advantage of Charm Blue Blus series very well. Whether it is sound quality, noise reduction or delay, the performance of Charm Blue Bluus 2 far exceeds the price of the product itself.

If you focus on the sound quality of headphones when choosing TWS wireless Bluetooth headphones, pay attention to the noise reduction experience of headphones. The performance of Blue Lotus 2 will not disappoint you. More importantly, this headset does not have a high price and is not subject to ecological limitations.
