Spy Earpiece: 5 Top Buying Tips

If you are due to start working undercover and need to purchase your first spy earpiece, there are several considerations to bear in mind.

The following tips will ensure you get the right product and therefore remain covert (i.e. avoid being spotted), hear exactly the information you need to hear, and feel comfortable wearing your earpiece all day long.

1. Smaller is better

The benefits of choosing the tiniest spy earpiece you can are twofold. Firstly, a minimal form factor ensures the piece remains hidden in the ear canal, keeping you covert.

Secondly, smaller earpieces are simply more comfortable; the smaller an earpiece, the more different user ear canals a brand or model is likely to fit without causing aggravation or pain.

2. Ergonomics

The best spy earpieces are not made straight, but feature a slight bend halfway down the length of the casing.

Often just an angle of 25 degrees or less, this bend ensures an earpiece can fit fully and correctly inside the ear canal without having to be forced (just pop it in and carefully twist into place).

3. Color it blind

Some earpiece providers provide only beige earpieces. Of course for light-skinned Caucasians these work fine, but for users with darker skin tones such earpieces can stand out and be noticed.

If you have the choice, always choose the casing color closest to your own skin tone.

4. Avoid interference and ground noise

Almost all wireless earpieces are based upon 'inductive' technology, with a full inductive earpiece system featuring:

· an in-ear earpiece

· an inductive loop (i.e. a flexible wiring loop that can worn under a shirt, built into the roof of a car etc.), which connects to the user's portable professional radio

· an optional wired or wireless Push To Talk (PTT) unit.

This approach is, on the whole, highly effective. However inductivity does have its quirks.

The two key issues to watch for are: EMI or 'electro magnetic interference' and ground noise.

EMI is caused by nearby electrical devices and installations and can disrupt the sound signal you hear. This makes it difficult to catch every word and can cause problems during sensitive operations. If possible, test different spy earpieces to assess their susceptibility to EMI.

Ground noise meanwhile is the underlying 'shhh' sound a product makes when active (turned on). Obviously this noise should not be distracting or confuse the messages you hear, however many users do like to hear a little ground noise (at a level, for example, that is just noticeable in a quiet room), as this assures them that the system is on and working.

Note: an alternative to inductive technology is newer 'transductive' technology. This uses much higher frequencies to completely avoid interference and requires its own special wiring loop system.

5. Avoid new suppliers

Buy your spy earpiece from an established suppliers with a solid track record and quality after-sales support and service. As with other products, choose a company you expect will stick around, as products that do not function from a company that no longer exists are near to worthless.
