Recently, friends introduced me to several small and flexible wireless headphones, after the pro-test, I think my friend's recommendation is very good, so I want to share with you these small-looking, in fact, wide sound range headphones, their noise reduction ability is also very good. Friends who have recently started the Bluetooth headset plan can take a look at the Bluetooth wireless headsets used in these several models.

Compared with the previous generation of products, the reduction of sound is about 60% improved, which is because South Carolina A2 uses a Bluetooth 5.2 chip and a 13mm super large dynamic unit, and even has the blessing of the exclusive SR sealing ring process and cavity vibration reduction technology, so the comprehensive performance of South Carolina A2 can have such a big improvement. The South Card A2, which does not lose the big-name headphones, is completely worth enough to reach the level of thousands of headphones, and even many digital enthusiasts and hifi enthusiasts spontaneously recommend the South Card A2.

On the left and right headphones of the Iron Triangle ATH-ANC300TW, there are two small MEMS microphones for picking up the ambient sounds.

The 7mm micro-dynamic drive unit allows Sennheiser Momentum TrueWireless to have a wide soundstage, even with dynamic output can be more abundant, as well as rich sound detail output. The frequency response of 5-21000Hz makes the bass of the headphones deeper and better, and there is a more high-frequency extension, which is really to restore every detail of the sound.
