森海塞尔 HD 660S2 耳机
有线耳机仍然吸引着那些喜欢最高保真度和长时间聆听而不是无线便利和噪音阻挡技术的观众。 Sennheiser 的 HD 660S2 专为这些人打造。它们采用轻巧的开放式设计和舒适的毛绒丝绒耳垫，超轻铝制音圈和通风磁铁系统可实现出色的音频再现。在低频时，它们产生的声压是其前代产品的两倍，从而产生更丰富、更准确的低音。除了携带袋外，德国设计、爱尔兰制造的罐头还附带 6.3 毫米和 4.4 毫米电缆，以及 6.3 毫米至 3.5 毫米适配器。

Smart Rope Jump Rope
Jumping rope is one of the best ways to burn calories, and now you can train and track at the same time with this smart rope. The rope combines form and function with comfortable 45 degree angled handles to help make this age-old workout more interesting. Other ropes on the market provide tracking, but none have a strand of bright white LEDs that are visible while you're jumping. View jump counts, calories burned, or the duration of your workout as the rope swings in front of you. All the data is then transmitted via Bluetooth to a smartphone app — meaning all you have to supply is some sweat and an epic workout soundtrack.
