Jawbone ERA

Best price: £79.99 (without charging cradle)

It might be small and dinky, but the Jawbone ERA delivers just as clear audio as its peers with huge boom mics. Owing to its compact size, the unit is comfortable to wear – you’ll forget you have it in after a while. The maker claims that it cancels background noise as it only picks up voices based on movement in the user’s jawbone, hence the name. We liked the neat charging cradle, but this costs extra.
