Earaku G2 headset: a buying guide for calls

**Bottom line:** The Earaku G2 (model J065) is an open-ear Bluetooth headset marketed as call-only, with a boom microphone. It is aimed at people who want to take calls and join web meetings on a phone or PC without blocking their ears — not at people shopping primarily for music sound quality. Be aware that the supplied information contains a specification conflict and several unverified points. **Who it fits:** Buyers who value an ears-open fit and want call features — a microphone, mute, and two-device multipoint connection — at a low price. The listing price is shown as ¥2,997 against a list price of ¥2,980 [S1]. **Who should skip it:** Anyone prioritising music sound quality, passive isolation, or independently verified comfort. The product calls itself call-only [S1], and the supplied information contains no music-quality claims. **Specification caution:** The supplied spec table lists the headphone type as "on-ear" and noise control as "active noise cancelling" [S1], while the description describes an open-ear design and ENC (environmental noise cancelling) that reduces surrounding noise at the microphone [S1]. These are likely different things from earbud-side ANC that blocks sound for the listener; do not assume isolation from the spec table alone. This cannot be settled from the supplied information and remains unverified. **Treat as manufacturer claims:** Up to 11 hours of talk time, roughly 300 hours standby, Bluetooth 5.3, a 270° rotating microphone, mute, two-device multipoint, about 28 g, a Japanese voice guide, and a one-year warranty are all seller statements [S1]; no independent test results are supplied. Real-world talk time, connection stability, and microphone pickup quality are unverified. **Check before buying:** The supplied information does not establish supported codecs, charging connector type, water resistance, the exact terms of the warranty (beyond initial defects), or whether a Japanese manual is included. For English-speaking residents of Japan, an English manual or app, and the language support of the local support channel, are also not stated — ask the seller. **Summary:** The call-focused concept is clear, but the terminology conflict between the spec table and description, and the absence of independent verification, are real weaknesses. This is a product for people who want a call microphone and an open fit, not isolation or music fidelity.
