The perfect in-ear monitor for anyone looking for a balanced, full-spectrum sound. The A4t delivers an immersive listening experience with a dynamic mid-range and powerful bass. It's a great option for single-instrumentalists and moderate mixes.
The A4t is the entry point for our exclusive tia™ technology, which provides an amazingly lifelike clarity and musicality to the sound signature.
Current lead time is 4 weeks from the time 64 Audio receives the impressions. You need to visit an audiologist to get your ear impressions made first. By purchasing from Bloom, you receive our attentive lifetime support. We'll assist during each step of the process. Keep in mind, all custom earphones orders are final.
