Know before you buy
The Aspire 2 is built for the stage with a durable ABS shell and a hybrid driver configuration that provides a balanced, clear sound profile. It also features -20 dB of passive isolation, which helps block out loud ambient stage noise so you can focus on your mix.
Apex Core is a pressure-relief system that vents internal air pressure from the ear canal. This reduces listener fatigue during long sessions and allows for a more open, natural soundstage compared to traditional sealed in-ear monitors.
Yes. The Aspire 2 features a LID (Linear Impedance Design) circuit, which ensures the sound signature remains consistent regardless of the output source. With an impedance of 13 Ω, they are easy to drive from standard 3.5mm headphone jacks or professional audio gear.
The IPX connector is a proprietary, highly durable connection system designed to be more resistant to sweat and moisture than standard MMCX or 2-pin connectors. This makes the Aspire 2 a reliable choice for performers who move around or sweat during live sets.
By combining a dynamic driver for the lows and a balanced armature driver for the mids and highs, the Aspire 2 delivers a punchy, full-bodied bass response alongside crisp, detailed vocals. This hybrid approach provides a versatile sound that works well for both musicians and casual listeners.
The Aspire 2 uses a universal fit design shaped to accommodate a wide range of ear sizes. Because the shell is made from lightweight ABS and includes pressure-relieving Apex technology, they are generally comfortable for extended wear, though fit can vary based on the ear tips used.
