Warranty

One year, handled by people who answer email.

Every product sold by TonePier is covered for 12 months from delivery against manufacturing defects. Because we sell through the official channel, your serial number is valid for manufacturer warranty service — no gray-market asterisks.

What's covered

• Drivers that fail, channel imbalance, dead DAC/amp channels
• Buttons, jacks, sockets and screens that stop working under normal use
• Batteries that lose more than 30% of rated capacity within the first year
• Stock cables and chargers for 90 days

What's not

• Physical damage: drops, crushes, bent pins, chewed cables (dogs love cables; warranties don't)
• Liquid damage, including sweat corrosion inside IEM shells
• Wear items: ear tips, foam pads
• Units opened or modified outside an authorized service center
• Products bought from other sellers — we can only stand behind what we sold

How a claim works

1. Email support@tonepier.com with your order number, a description, and a short video or photos showing the fault.
2. We triage within 2 business days. Most issues are diagnosed straight from the video.
3. First 30 days (DOA): we replace the unit outright and cover shipping both ways.
4. Day 31–365: repair or replacement, our call based on parts availability. You ship to our US returns address; we cover the trip back.

Brand-backed service

[PENDING NEGOTIATION — keep or cut per final agreements:] For FiiO, SIMGOT, Moondrop, Shanling, SMSL and HiFiMAN products, warranty service is additionally honored through each brand's official US service process. Where a brand runs its own US repair center, you may choose to deal with them directly — your TonePier invoice is your proof of authorized purchase.

After year one

Out-of-warranty repairs: we'll quote parts and labor at cost through our service partners. Old gear deserves fixing, not landfill.
