Control your performance with the professional universal in-ear monitors 64 Audio Aspire 4, specially designed for musicians and live music professionals. In a new form factor, priority is given to ergonomics without sacrificing performance. Aspire was developed by the same innovative team responsible for creating industry-leading audio equipment, known by the company 64 Audio.
Features:
- Frequency range 20 Hz - 18000 Hz;
- Filter: -20 dB;
- Sensitivity: 104 dB;
- Impedance: 11 Ohms;
- Dynamic bass, clear mid frequencies, stage depth;
- Hybrid configuration: one dynamic driver and three balanced armature drivers distributing different frequency ranges.
Bass instruments sound very smooth on the Aspire 4. Everything in its timbre is very elegant and clean. Although it may not vibrate as strongly as desired, the low frequencies remain incredibly transparent. This provides a very dynamic bass that will satisfy most tastes.
If the goal of Aspire 4 is to set the standard for musicians and studio professionals, then the mid frequencies will tell you about it the best. There are very few drops in the mid frequencies, as the frequency response remains mostly flat. The lower mids and main frequencies are the most balanced with each other, but it seems that the response slightly decreases before sharply rising in the upper mid frequencies.
The high frequencies mostly show good control, but some frequency bands leak and create sharp peaks.
The patented 64 Audio technology is seamlessly integrated into the headphone housing. The pressure relief channel provides controlled ventilation through acoustic filters. Aspire 4 users benefit from the flagship 64 Audio technology with -20 dB isolation. 64 Audio rightly noted that any IEM headphones have one drawback inherent in their advantages. All emitters in such solutions operate in a closed volume, which affects both the sound and the user's hearing.
The Apex Core technology aims to reduce listener fatigue by reducing excessive air pressure on the ear canal. This ventilation allows musicians and music enthusiasts to use headphones comfortably for longer periods.
