The Plantronics headsets has gained popularity over years due to its affordable and best sound quality. Designed to go well with your mobile device in a hands free environment, like driving a car.

Here I am comparing two models of Plantronics Explorer 50 and Plantronics M55.

This is due to the fact that M55 is almost double the cost of Explorer 50, so I must understand what is that I will get by spending more money ?

Both of these Plantronics headsets are within $40 budget range with features that are handy and well designed.

What makes them so special for review is the Deep sleep mode which allows the Plantronics Explorer 50 & M55 headsets to stay active for up to 3 / 5 months without the need to be charged !! [Deep sleep mode gets activated after 90 minutes idle mode]. It can be quickly reactivated too 🙂

Added to this is the Voice-activated commands which makes you real hands-free.

So recommendation is that of you are really hardcore ourdoor freak, then better to go for Plantronics M55 which will provide you most benefit of Deep sleep mode upto 5 months and standby time of 16 Days 🙂 but that too at cost of spending $10 more than Explorer 50. Also M55 is slightly lighter than Explorer 50.

Hope this helps
