When Beyerdynamic's headphone DT48 was introduced in 1937, the word "headphone" did not exist, and the brand was revered as the father of headphones. In the following time, Baia also launched the world's first pair of quad headphones, the DT204, and the first pair of electrostatic headphones, the ET1000. Its classic products DT880/DT990 and T1 have also led the trend of headphone development, and the brand has a deep technical accumulation.
 
Because the amount of data transmitted by Bluetooth is much lower than that of wired transmission, the Bluetooth headset will not have too good sound quality, and the traditional HiFi manufacturers do not focus much in this field. BT is the abbreviation of Bluetooth, and BTA stands for Bluetooth Advantage. It is not difficult to see that Byron BTA's product positioning is higher. But the Byron BT didn't perform badly either, having been named one of the best in-ear Bluetooth headphones of 2018 by the review media PhoneArena.
 
Compared with the BT version of 869 yuan, the main upgrade of the BTA of 1499 yuan is the addition of a specially customized digital signal processor (DSP). Compared to Bluetooth headsets without DSP, there is less data loss and higher audio quality. The addition of DSP is also one of the main means to improve the sound quality of Bluetooth playback devices. In terms of specific performance, the BTA opening sound is amazing, the low frequency is tight and powerful, the sense of speed and elasticity are remarkable, although the sense of volume is not strong, but most pop music can do it. The mid-range vocals are strengthened, with moderate distance and slightly thinner high frequencies, but the density is good, and the resolution and the preservation of sound details are also worth affirming. The difference between BT and BTA is that the resolution is slightly inferior, but the overall performance is still outstanding compared to products in the same price range.
 
In other aspects, the Byron BT only supports aptX Bluetooth encoding, which is more suitable for Android phones, while the BTA supports aptX and AAC. Both BTA and BT adopt a rear-mounted wearing style, and the addition of magnetic design also makes storage more convenient, and the battery life of 7.5 hours ranks among the top in the same category. It is worth noting that BTA's unique charging base, users need to keep it properly, once lost, they will face the trouble of not being able to charge the earbuds.
