The Sony BT140Qs are some of the top rated, affordable headphones to incorporate Bluetooth wireless technology.
I ordered these to try out, and now I am absolutely relying on them. The sound quality is mediocre compared to most wired headphones, and this is definitely the tradeoff for the Bluetooth capability. However, the battery life is fantastic considering their size, coming in at around 4-5 hours.
I use these often with both my iPhone 4 and my MacBook Pro. They’re great in situations in which you are walking around and need your hands free. I’ve used these for everything from doing dishes to pull-ups. The signal from the iPhone is definitely far weaker than the MacBook Pro and has difficulty passing through the body, which means I need to keep the phone on the same side as the right earpiece which has the antenna.
On the other hand, it goes through a wall or two pretty well. All in all, I’m very happy with these earphones, and enjoy taking advantage of the wireless versatility.
