Founded in 2013, 1MORE is one of the enterprises in the Xiaomi ecological chain, and the words "1MORE DESIGN" can be seen on the packaging of many Xiaomi earphones. Although it has not been established for a long time, the three-unit coil iron earphones and four-unit coil iron earphones launched by 1MORE have won numerous awards, including the United States "Consumer Reports" and Japan's VGP, and many authoritative institutions and media have praised these two earphones, and the evaluation is even higher than the products of many old manufacturers, which shows its strength.
 
1MORE's strength is also reflected in sports headphones, with its iBFree Sport Smart Sports Headphones scoring 76 points in the US Consumer Reports, tying for the top spot in its category with the Bose SoundSport Wireless, Jabra Elite Active 65t and JLab Epic Air. In Headphones Addict's feature article "Workout Headphones with the Best Sound Quality", 1MORE iBFree is considered to be the most cost-effective product.
 
iBFree has been removed from the official sales channel, replaced by an upgraded version of iBFree, which is still priced at 249 yuan. Compared with the basic version, the appearance of the upgraded version has not changed much, and the improvement is that the waterproof level has been upgraded to IPX6, and the Bluetooth version has been upgraded from 4.1 to 4.2, and it no longer supports aptX, but supports AAC Bluetooth encoding.

The battery life is 8 hours, and it takes 2 hours to charge, and the overall performance is excellent, but unfortunately it does not support fast charging.
 
The iBFree Plus uses a larger 10mm diameter aerospace metal composite diaphragm, which makes the sound fresher than the basic version. Its low frequency volume is sufficient, the layering and density of the midrange have been improved, and the recognition of the vocal position has been greatly improved. In terms of instrumental music and spatial expressiveness, the upgraded version has also been improved, the stimulation of the instrument is greatly reduced, and the basic quality is very good.
 
The iBFree Sport smart sports earphones, which won the first place in the "Consumer Reports" in the United States, are different from the upgraded version of iBFree in that they have added a mobile phone APP, which can record the distance, route, calories burned and other data of running. In terms of appearance, configuration and sound quality, iBFree Sport is almost the same as iBFree upgrade, but the battery life is shortened to 5 hours, and it does not support waterproof, only supports in-line control and dustproof.
 
1MORE's most gorgeous sports earbuds are iBFree 2, which supports Tencent's Dingdong voice assistant, which can obtain data such as exercise duration, distance, heart rate, step count and calories burned through verbal questions. Of course, these data can also be viewed in the mobile app. And iBFree 2 comes with 4GB of local storage, so you can listen to songs without connecting to your phone.
