我用低端的sp500n，看B站感觉不到延迟

廠方更表明已經改良左右耳機的配接天線，務求帶來更穩定的連接。

Almost perfect. Bit bulky and bassyWF-SP700N 01/05/2018 by EUsynthpop (USA)
Pros:
- Great sound quality, though low end is too strong
- Companion app with EQ presets to level off the bass
- Multiple modes of noise cancellation
- Excellent fit
- Strong stable connection

Cons:
- Big and bulky. Look like giant beans
- EQ presets only, no custom adjustments
- Slight latency when watching videos. Lip sync is off
- Case cover slides to the side so it doesn't provide any downward pressure on the buds to ensure contact with the charger.Show less

连接稳定性加强了
看视频延迟还是有一点
