Perhaps no one would have thought that the big hit in the headphone industry in 2023 this year is actually an open Bluetooth headset, and the words "I want to wear headphones and immerse myself in my own world" seem to be very old-fashioned. For in-ear headphones, we are more inclined to look at hardware parameters, such as driver units, resolution, sound field, and dynamics, so what functions should we look at when buying open-back headphones?
Open-back headphonesHow to choose
Wearing comfort
An important factor in choosing open-back headphones is that they don't fit in the ears, so in my opinion, wearing comfort is the top priority of open-back headphones, and if it's not comfortable, then there's no point in making it open. At present, the style of open-ear headphones is mainly divided into several types, namely ear clip type, Bluetooth ear hook type, TWS ear hook type, most of the open earphones are TWS ear hook type, among which the style of ear hook type is also more diverse, how to choose is more according to the suitability of personal ear shape and preference to choose.
Sound quality experience
Secondly, we can feel the sound quality effect of open-back headphones, open-back headphones are missing the physical noise cancellation that plugs the ears, so first of all, we must Xi the sound of headphones as your bgm. It is recommended to give priority to the resolution and sound field in a quiet environment when experiencing the sound quality, and then go outdoors to feel how much volume you need to be able to listen to (some open-back headphones are not recommended if you can't hear 100% of the volume outdoors), sound leakage and call effect.
Other features
The core of the earphone is the sound, but other functions can not be ignored, which is important for the convenience of our daily use, the parameters that can be paid attention to are: battery life (earphone life and charging case battery life), Bluetooth chip (determines the stability of the connection, to avoid intermittent listening), appearance (small and easy to store), etc.
Next, I will use this 100 yuan cost-effective open-back headphones I chose to wear Ling OSAs an example, let's talk about my feelings about using open-back headphones
WearComfort
Dai Ling os2 this shape is my favorite,The part hanging behind the ear is to play a role in stability and support,And there is no other element added on it,If you add other elements to hang behind the ear, the comfort will be more general,It is easier to press the back of the ear。 In terms of wearing feeling, the comfort is excellent, and the stability is also good, after wearing the earphones, there is no feeling that the front end is very bulky and the back end is very light, and the weight distribution of the earphones is relatively reasonable.
Sound quality experience
My requirements for the sound quality of open-back headphones are that the mid-bass audio is balanced in a quiet environment, so that they can be clear when used outdoors, and the sound leakage should not be excessive. The feeling of listening to this Dai Ling OS2 is a kind of surround sound (this is different from the feeling of putting a speaker around you), that is, there is a feeling of BGM in the ear, and the 360° enhanced surround sound field can feel the stereo surround sound and the sound is layered. When outdoors, adjust the volume to 50%-65% to make it easier to hear. But after all, in the early 100s, the sound quality of the three frequencies is relatively balanced, but when listening to rock and roll, etc., including the lower potential of the drums, is still missing.
In addition, on the issue of sound leakage, if it is in the office, the colleagues working next door can hardly hear the sound (can hear and only hear the other party listening**, but what is actually heard can't be heard), it is more bold outdoors, after all, there are many sounds around, the sound in your headphones is not clear to the people around you, so the open headphones are not next to the ears to put a speaker, this is still different, the sound is diffuse sound, Dai Ling OS2 is with DTS directional audio,** It is directional sound transmission into the ear, so there is less need to worry about sound leakage.
Other features
The Bluetooth version of the OS2 is currently the newer 53. Support AAC SBC encoding analysis, Bluetooth effective distance is 10 meters, basically the Bluetooth version of the headset of 1,000 yuan is also this configuration, so there is no problem in the stability of the Bluetooth connection.
The battery life is officially written to charge for 2 hours and the battery life is 24 hours, I use it for about 4 hours a day, and it is almost true that it is charged once a week, and it is OK.
Finally, I personally like the shape of the charging compartment, a small square, stacked earphones, can be easily placed in the pocket, compared with the rectangular charging compartment of other open earphones, the charging compartment of OS2 will be more convenient to carry.
2023 Annual Inventory Overall, Dai Ling OS2 is a ** in the early 100 yuan, and the sound quality belongs to the balanced sound effect of white boiled water, but the sound leakage suppression is better, and there is also a feeling of surround sound in the ear when listening. In Bluetooth and other functional parameters are up to standard, the setting can be comparable to thousands of yuan of headphones. In addition, in terms of the wearing comfort of the headphone shape, I personally think that it can score 95 points, and it will not squeeze the ears when worn for a long time, and the stability is high after wearing, so I don't have to worry about being touched when getting on and off the subway. As an entry-level open-back headset, the cost performance is still very high.
