Shure is well-known in the field of microphones, and in the field of headphones, it is known as the "Big Four Manufacturers of Moving Iron Headphones" along with Interme, UE and Weston. Since its inception in 1925, Shure has been deeply involved in the field of moving iron headphones, and has several technologies to avoid the physical defects of live iron headphones. And all of Shure's earbuds fit snugly into the inner ear for great comfort. Shure's transparent cavity design is also a highlight, and the delicate engineering inside the headphones allows users to see them at a glance. From the scene of the Grammy Awards to the stage of popular variety shows such as "I Am a Singer", performers can be seen wearing Shure headphones.
 
Shure's Bluetooth earbuds belong to the SE Sound-isolating Earbuds family. Its Bluetooth earbuds are generally named after "SE three-digit BT1", such as SE846-BT1. The three digits in the middle of the model, the first digit indicates the grade, "8" is the highest at present, and "1" is the lowest; The second digit is the number of headphone units; The third position indicates the number of generations of the product. For example, SE846 represents the flagship 4-unit 6th generation earbuds. In addition, the model number of Shure headphones is occasionally written as SE846-CL-BT1 and SE846-BLU-BT1, etc., with the English letters in the middle indicating the color, CL (Clear) is the transparent color, and BLU (Blue) is blue.
 
Among Shure Bluetooth earbuds, the highest positioning is SE846-BT1, with 4 moving iron units of the top configuration, the price is 6888 yuan. And it is equipped with two technologies that are first used in Shure headphones, "low-frequency filtering technology" and "customizable frequency performance". The former uses ten precision-welded stainless steel plates to form a 4-inch high-quality acoustic transmission path, resulting in undistorted low-frequency performance. It can be understood as a "labyrinth box" design in the speaker, that is, the use of airflow circulation in a small cavity to improve low-frequency performance. This technology avoids the problem of unnatural low-frequency elasticity of the moving iron unit. The "customizable frequency performance" is actually the design of the replaceable catheter, which simply means that the attenuation of the high-frequency or low-frequency part of the sound can be achieved by replacing the conduit to obtain a different listening experience. Among them, the white tube gives a brighter tone, the black tube has a warmer tone, and the blue tube is installed in the headphones from the beginning for a balanced tone. Other earbuds, such as AKG's flagship earbuds K3003, also have an interchangeable tube design.
 
In terms of actual hearing, the SE846-BT1 has made great progress on the basis of the brand's consistent tuning. There are no obvious shortcomings in the three frequencies, the low frequency volume is sufficient, the elasticity is excellent, the mid-frequency density is high, relatively thick, suitable for playing back male voices, and the high frequencies are not bright, but very full. Overall, SE846-BT1 can be called a "fever reducer". In other aspects, the SE846-BT1 has a wide range of luxurious accessories, including 8 pairs of ear tips such as foam ear tips, elastic ear tips, yellow foam and three-section sleeves, as well as a carrying case, earphone cable, adapters and polishing cloth.
 
Shure's other products, SE535-BT1 use 3 moving iron units, the price is 3888 yuan, and SE846-BT1 has the same rich accessories. SE215-BT1 is 1 moving coil unit, and there is a special edition SE215SPE-BT1, both of which are award-winning models of VGP 2018 SUMMER, and the price is 1298 yuan. The difference between the SE215SPE-BT1 and the SE215-BT1 is that the former optimizes the cavity structure at the rear of the unit, which allows for greater airflow and better low-frequency performance. The 449 yuan SE112-BT1 is Shure's most entry-level Bluetooth earbuds, and it is also the winning model of VGP 2018 SUMMER Bluetooth earbuds. The SE112-BT1 uses a single moving coil driver, and the main difference from Shure's other Bluetooth earbuds is that the cable cannot be changed.
 
In other aspects, Shure's Bluetooth earbuds have reached an excellent battery life level of 8 hours, and a fast charge of 2 hours can listen to songs in 15 minutes, which is also excellent compared to similar products. And they can both connect 2 devices at the same time, and neither supports aptX or AAC Bluetooth encoding.
