XTONES

■ Item Description
Welcome to XTONES. We specialize in curating premium Japanese audio equipment and exclusive JDM boutique items for audiophiles worldwide.

Up for sale is the Melody Wings "Jupiter", an exceptional single dynamic driver (1DD) In-Ear Monitor that is rapidly gaining a reputation as the ultimate "audiophile beater" for everyday use.

Combining high-end aesthetics with modern convenience, the Jupiter features a beautiful, unique Natural Birch Wood faceplate and an ergonomic 3D-printed resin shell by HeyGears. Unlike traditional IEMs, the Jupiter is designed for the modern smartphone user. It includes a premium 0.78mm 2-pin cable terminating in a USB-C plug with a built-in high-performance decoding chip (DSP), allowing you to bypass your phone's internal audio and experience true high-resolution sound without needing an external DAC or amplifier.

Guaranteed 100% Authentic product sourced directly in Japan.

■ Key Features

10mm Titanium-Plated Dynamic Driver: Delivers a fast, tight bass response, crystal-clear mids, and an expansive, airy treble that brings energetic genres to life.

Built-in USB-C DAC/Amp: The included cable features an integrated audio decoding chip (supporting up to 32bit/384kHz) and an in-line microphone with volume controls for maximum convenience.

Premium Natural Birch Wood: Each earpiece showcases a stunning, one-of-a-kind wood grain pattern, giving it the look and feel of a boutique, high-end IEM.

Ergonomic 3D-Printed Shell: Manufactured using highly precise HeyGears PAU20 medical-grade resin for a fatigue-free, incredibly comfortable fit.

Shipments to the United States
For U.S. orders under USD 2,500 (item price, excluding shipping), we ship Delivered Duty Paid (DDP). Applicable import duties and standard carrier customs / import processing fees are handled on our side. You should not be asked to pay extra import charges after checkout. For dutiable items (audio gear, accessories, and similar), U.S. shipping rates may already reflect import-related costs—please do not expect a second import bill from the carrier on eligible DDP shipments. eBay Sales Tax collected at checkout, if any, is separate from customs / import fees.

Shipments to the European Union
From 2026, the EU applies new import rules for low-value parcels.

Item value €150 or less (excluding shipping): We ship with Delivered Duty Paid (DDP). Import duties and standard customs processing for eligible low-value shipments are handled on our side, so you should not need to pay extra import charges at delivery.

Item value over €150 (excluding shipping): Import duties, taxes, and related charges are not included and are the buyer’s responsibility, as before.

The United Kingdom is not part of this EU low-value rule.

Other countries
Import duties, taxes, and related charges are not included in the item price or shipping cost and are the buyer’s responsibility.

Our Guarantee:
If an item arrives damaged, defective, or significantly not as described, please message us right away. We will take full responsibility and work with you quickly and fairly to resolve it.

Returns:
We do not accept returns for change of mind or buyer’s remorse.

Customs & Unclaimed Packages:

Where import duties are the buyer’s responsibility, items returned due to unpaid customs duties or being left unclaimed will not receive a full refund. Any return shipping costs and resulting loss in value may be deducted from a possible refund. U.S. DDP orders and eligible EU low-value DDP shipments are excluded from this unpaid-duty case.
