Balanced sound is key in moderation. We have two target audiences: First, moderators whose in-ears should be discreet. Preferably invisible. If this describes your needs, we recommend the extremely compact and customized HL2 (LPH) and HL3 series (silicone). The HL2104, in particular, stands out for its optimal sound.
If you need a compact option for good communication, we recommend the HL1 series with headset option. The HL1202 would be a perfect solution.
