Specs before marketing

Battery life, latency and weight are measured by us on the unit in the box, not copied from the manufacturer's sheet.

What we check before we list

Battery life, timed

We run the battery at 50% volume until it dies and publish the hours we get. On headphones the gap to the official figure is usually two hours.

Latency, measured

Milliseconds from tap to sound, on Android and on iPhone separately. Under 80 ms is playable, over 200 ms shows on video.

Spare parts

We only list devices whose battery or cable can be replaced. Every page says which part we keep in stock and what it costs.

Every batch goes on the bench on arrival

We take ten units from each batch, switch them on, charge them fully and pair them with three phones. If two in ten show the same fault, the batch goes back to the distributor and the page stays "out of stock".

2-year warranty

On the invoice, for private customers. We do not ask for the original packaging for a repair.

In-house service

We repair on site; the device is not sent to another country. Average turnaround is nine days.

Firmware tracked

We publish the version shipped and email you when the manufacturer releases a new one.

Compatibility, batteries, service

How do I know it works with my phone?
Every page gives the minimum Android and iOS version and the audio codecs supported: SBC and AAC work everywhere, LDAC and aptX only on some Android phones. If a device needs an app, we also say whether it works without an account.
Can the battery be replaced, or do I throw the device away?
On everything we list the battery can be changed, and the page gives its part code and price. A lithium-ion battery loses around 20% of its capacity after 500 full cycles, so with daily use you notice it in the second year.
How does the warranty work if it breaks?
Write to us with your order number, send the device with a courier we pay for, and you get a service number you can follow in your account. In the first 30 days we replace it outright, without repair, if the fault is a manufacturing one.
