◆ Why These Buds

🎵 11mm Wide-Range Speaker + 24-bit Hi-Fi

A bigger 11mm dynamic driver delivers controlled bass and crisp highs. Samsung Seamless Codec preserves 24-bit / 96kHz audio from your Galaxy phone, with a 9-band EQ for tuning to taste.

🤖 Galaxy AI — Adaptive ANC + Real-Time Translation

Adaptive Active Noise Cancellation auto-tunes to your surroundings. 360 Audio with Head Tracking for spatial sound. Galaxy AI delivers real-time interpretation directly to your ears, paired with a 6-mic array using DNN voice isolation.

🌬️ Open-Fit Comfort Design

No ear tips — the open-type Comfort Fit shape is built using ear-data-derived computational design, with a metal blade for stability. Ideal for all-day wear and ambient awareness without needing to remove the buds.

RETURN POLICY · 30 DAYS

Not happy with your order? You have 30 days from the day it arrives to start a return. Here's exactly how it works:

Returned Sealed: Items returned in their original factory-sealed condition get a full refund once we receive the package.

Returned Opened (when sold sealed): A 20% handling fee applies, since we can no longer offer the item as "sealed".

Returned Open Box / Used: Items sold open box or used can be returned within 30 days under eBay's "as described" rules. Item must come back in the same condition it shipped.

Box / Accessories Missing: If parts, the original packaging, or accessories aren't included with the return, we may charge ≥20% or refuse the return outright.

Account Sign-Out (where applicable): If the item is paired to a personal account (Apple ID, Google, Samsung, Nintendo), please sign out and factory reset before shipping back. We can't access items left signed in — they'll be returned at your cost or charged a third-party unlock fee.

Inspected on Arrival: Every return passes through a check before refund is issued. Items must come back in the same condition they were sent.

🔒 Warranty: Manufacturer warranty handling depends on the brand's regional policy — most international warranties only apply in the country of origin. For US-side coverage, consider an extended plan from CPS (Consumer Priority Service), a third-party provider we've worked with.

❓ FAQ

Q: What condition is this item?

Refer to the Condition Module near the top of the listing — it shows whether this item is sealed, open box, or used, along with the specific grade and any cosmetic notes. Every Omega listing is graded honestly.

Q: Is this a US or international version?

Most of our items are international (global) versions. Hardware is identical to US-spec models, but software regional defaults, packaging, and (for chargers) plug type may differ. The exact variant is listed in the model number under the product name above.

Q: Will this work with my device?

Check the Compatibility module up top for confirmed support. Most of our audio accessories work with both Android and iOS via standard Bluetooth. Watches typically require a specific OS (e.g., Android for Galaxy Watch). Chargers fast-charge devices supporting matching protocols (PD/PPS). If you're unsure, message us before buying.

Q: How do I pair / connect this?

Most accessories pair via Bluetooth or the manufacturer's companion app. Bluetooth devices: enable Bluetooth on your phone, put the accessory in pairing mode (see manual), and select it from the list. App-based accessories: download the app from the Play Store / App Store and follow in-app pairing instructions. Most pair in under 30 seconds.

Q: Is a charger / power adapter included?

Most modern accessories ship with a charging cable but typically not a wall plug adapter (eco-friendly packaging). You can use any standard USB power source. For chargers/power adapters as the listed product itself, the brick IS the product — see the "What's in the box" section for full contents.

Q: Is there a warranty?

International brand warranties generally only apply in the country of origin. For US-side coverage we recommend an extended plan from CPS (Consumer Priority Service), a third-party provider. You're also protected by our 30-day return window and the eBay Money Back Guarantee.

Q: When does my order ship?

Orders dispatch from our Miami, FL facility once payment clears. Tracking info is sent the moment the package leaves us. Carriers we use: USPS, FedEx, UPS (chosen by destination and speed).

Q: How do returns work?

30 days from delivery. Sealed → returned sealed: full refund. Sealed → returned opened: 20% handling fee. Open Box / Used: returnable per eBay's as-described rules. If the item is paired to a personal account (Apple ID, Google, Samsung, Nintendo), sign out and factory reset before sending back. Full details in the Shipping & Returns tab.
