Etymotic Research ER-9 Single Filter for Musicians' Earplugs (Clear)

Designed for use with the Westone's DefendEar Concert (Style 49) Musicians’ Earplugs. Etymotic filters feature a flat frequency response that allows musicians to hear their performance accurately while providing hearing protection. The ER-9 provides flat 9 dB sound reduction through 2 kHz and slopes down to 15 dB at approximately 8 kHz. It is the ideal attenuator for musical situations that may not require as much attenuation as the ER-15 or ER-25 filters provide.

Doc fetch goes through Layer's Aerospike pull-through cache; cache hit served the row without touching turbopuffer. The similar query asks Layer for nearest neighbors of the stored product vector — queries don't go through the doc cache, so no cache header is set.
