We ended the last piece by saying that you shouldn’t use the featured product to guard the life of America’s president. However, we’ll begin this piece by saying that, if you are looking to guard President Obama this summer, then you’re getting closer to the right idea with this earpiece.

The GP340 covert earpiece is a serious piece of equipment. This earpiece comes attached to one of those curly receivers, the kind you’ve seen Agent Smith wearing in The Matrix movies. The GP340 earpiece is a device designed for use with the Motorola GP340 range of two-way radio devices.

This is an understated earpiece that you use instead of making your presence felt, when subtlety and understatement are the aims of the game. If you’re concerned with security or protection, then the GP340 could well be the earpiece for you.

Earpieceonline lists this bad boy for £27.50, so it’s only a couple of quid more than the GP300, but it’s a couple of quid worth paying, especially if you value discretion.

There’s also no need for any kind of adaptor when you buy the GP340 earpiece, this model has a multipin plug that can connect directly to any Motorola two-way radio. In addition, there’s a built-in ‘push to talk’ button and microphone, but it is considerably smaller than the one found on most other models.

The GP340 earpiece features the same sprung clothing clip as our last model, a surgical grade acoustic eartube (as well as a spare tip) and a Kevlar-reinforced cable. It also comes with a snazzy drawstring pouch as well. Add to that a 12-month warranty (included in the price) and you’re definitely onto a winner.

Sound-wise, the GP340 earpiece provides clear, reliable sound and performs well in trying weather conditions.

However, the GP340 earpiece is not quite a top-range product, it represents fantastic value, for sure, and it works fine for most purposes, but if you have specialist requirements, then you should probably stick with this series and see what else is out there.

Overall, the GP340 earpiece is an excellent product that offers fantastic value for money. It would do a good job in most situations and comes pretty highly recommended all round.

Next episode, we take a look at the CP040 earpiece, a device specifically designed for use with the GP300 and, um, CP040 radio series. If you’re still looking to guard The President, you might want to skip that one and go straight to part four.
