## Description

Sennheiser True Wireless Black 200 Series

Review: Completely disappointed - waste of money - I ordered these earphones as a gift, trusting a well-known brand, but I was very disappointed. One side of the earphone didn’t work, and since it was a gift, the recipient didn’t tell me, so I missed the return window. The quality is not worth the price. Honestly, you’re better off buying earphones from other brands like Boat, which offer similar or even better quality at a much lower cost. Don’t be fooled by the brand name—these are not worth it.

ゼンハイザーらしいクリアでバランスの良い音質が楽しめる完全ワイヤレスイヤホンです。 低音は量より質を重視した締まりのあるタイプで、中高域は透明感がありボーカルが聴きやすい。 装着感は軽く、耳にしっかりフィットする形状で長時間でも疲れにくい。 Bluetooth接続も安定しており、普段使いから音楽鑑賞まで幅広く使える万能モデルだと思います。
