SL-E2 / IN-EAR STUDY
Drift / E2
Small form. Many experience decisions.
An in-ear audio concept for a coordinated brand collection. Tip fit, comfort, voice pickup and charging-case behavior are developed alongside the acoustic direction.
Plan this sampleDEMO / every specification, MOQ and schedule is illustrative.
EXAMPLE SPECIFICATION / NOT A PRODUCT RATING
Define the experience inputs.
- Driver concept
- 10 mm dynamic architecture
- Connection target
- Bluetooth 5.3 design route
- Acoustic scope
- Tuning + noise-control evaluation
- Runtime target
- 6 h playback at agreed settings; unverified
- Charging
- USB-C case-input concept
- Fit
- Three tip-size concepts
- Planning MOQ
- 1,000 sets / finish, illustrative
No ANC attenuation, hearing benefit, runtime or codec certification is claimed. Final features depend on platform scope and sample evaluation.
What changes with the brief?
- Tip set, case finish and markings
- Prompts and control mapping
- Acoustic reference and retail insert
Agree which platform functions are retained and which changes need a new engineering or sample review.
What should the sample resolve?
- Tip-fit feedback and seal-dependent response
- Voice samples in agreed noise scenarios
- Case charging, pairing and reconnect states
Methods, acceptance limits and reporting format must be agreed. No result or certification is implied.
What should the dossier retain?
- Listening reference and fixed sample settings
- Fit notes by tip size
- Voice and reconnect sample record
THE SAMPLE ROUTE
A session for each decision.
Appearance model → fit / tuning sample → device trial
Timing depends on the scope.
Illustrative first tuning sample window: 20–30 business days after platform review.
Tooling, firmware changes, materials, test scope and unresolved findings affect any real schedule. Request a program-specific quotation.

What has to be nominated before evaluation?
Listening reference and fixed sample settings. Attach a version identifier to the sample and consolidate review comments in one record.
Is the example MOQ a current commercial offer?
No. Material availability, configuration, tooling, packaging and capacity have to be quoted for the actual program. This demonstration does not sell the concept.
What evidence remains open?
No ANC attenuation, hearing benefit, runtime or codec certification is claimed. Final features depend on platform scope and sample evaluation.
