Hotspot Engine Project In the past 2023, if you want to say that headphones are the hottest, I think the answer must be noOpen-back bluetooth headphonesThere are already a lot of popular models on the market, so which open-back headphones have better comprehensive performance and are more recommended? It just so happens that I have successively evaluated a number of open Bluetooth headsets, and their comfort is undoubtedly quite high, after all, they do not enter the ear, do not close the ear canal, no foreign body feeling, no ear canal compression, and there is no pressure to wear it for a long time, and some models are very outstanding in terms of sound quality, wearing, battery life, calls, etc. Next, I will share with you a brief science of open-back headphone knowledge, purchase skills, and comments on 5 very popular open-back headphone brands on the market! 
How to choose an ear-clip Bluetooth headset, I picked a few key points.
Comfort should not only be ergonomic, but also as light as possible.
Headphones are devices that often need to be carried around for a while, especially when working, studying, or traveling. If the headphones do not have a certain ergonomic design, it is easy to cause discomfort, and long-term wear may cause ear pain, the lighter the weight, the better, reduce the overall burden from the source, and the ears are better adapted to long-term wear. And now the trouble of wearing glasses is also something to consider, and the compatibility with glasses should be considered.
The sound quality is mainly concerned with the sound generating unit and acoustic technical background.
The sound unit can directly affect the sound quality, a good speaker mainly depends on the size, the openness of the entire sound range depends on the size, the larger the size of the sound unit, the better the sound quality foundation, the wider the sound field. Generally, around 15mm is already a large size.
Powerful brands will study their own sound quality adjustment technology, such as tuning, positioning technology, etc., these professional acoustic technologies are usually jointly developed and applied by acoustic engineers and audio expert teams to ensure that headphone products achieve the best performance in terms of sound quality, comfort and function, so generally small brands do not have the capital to support the research and development of acoustic technology.
Novices recommend choosing a big brand for more security.
When buying headphones, the first thing to consider is the professional strength of the brand. Choose a professional brand, these brands usually have rich experience and a professional R&D team, which can ensure the quality and effect of the product, and can avoid the quality is not guaranteed, the technology and strength of the general Internet celebrity brand are relatively weak, and the quality cannot be guaranteed, and these brands are prone to face bankruptcy, resulting in after-sales problems that are difficult to solve. The popular open-back headphone brands on the market include Bose, Nanka, JLB, Sony, Philips, etc., among which JBL and Nanka brand open-back headphones have a very good reputation and credibility, and you can start with reference according to your own liking.
The longer the battery life, the better.
For users who need to use the headset for work or study for a long time, the long battery life can improve work efficiency and learning effect. They don't need to interrupt work or study to charge the earbuds, and frequent charging will increase the number of charge-discharge cycles of the battery, which may lead to a decrease in battery life, so long battery life earphones can also extend the life of the earbuds in disguise.
Call quality requires a better microphone.
The key to the longevity of the headphones is whether there is an anti-attenuation design.
Nowadays, the quality of headphones is relatively high, so the quality of headphones is also getting higher and higher, with long-term performance stability, to avoid excessive wear and tear and decline in user experience. Therefore, a unified anti-attenuation design should be carried out on the chips and materials, which can ensure that the open-back headphones are not easy to loosen or deform during long-term use, and the sound distortion or sound quality should not be reduced during long-term use.
