We had a clinic come in last month needing to replace their old screener, and what they really wanted was something that could handle both air and bone conduction without the complexity of a full diagnostic suite, so I showed them the SY-G055-1 and they were pretty much sold once they saw teh frequency range goes form 125Hz all way up to 8000Hz on the air side, with bone conduction starting at 250Hz and topping out at 6000Hz.

Frequency error stays under 1% which matters more than most buyers realize—if you're trying to track threshold shifts over time, that tiny drift adds up, and the distortion is tight too, below 2.5% for air conduction and under 5% for bone, and the attenuation step is 5dB with a 1dB error tolerance which is actually better than a lot of units in this price bracket.

One thing people don't always think to ask about is the masking capability—it uses white noise for masking which works fine for routine testing, but if you're doing advanced stuff like Stenger or tone decay, this model isn't really suited for that, it's more for straightforward threshold testing and screening, and the 2 independent channels give you enough flexibility for basic contralateral masking without overcomplicating things.

It's CE certified so for European buyers that's usually fine, we keep stock on most accessories like the TDH39 earphones and the B71 bone conductor, and the USB data transfer is handy for pulling results into your system, though the software isn't the most intuitive thing I've ever seen.

Lead time is usually 2-4 weeks depending on the batch, and the MOQ is 5 units, but if you need a sample for evaluation our company can sometimes work something out, just ask.
We typically require a minimum order of 10 units for this model, but we can discuss smaller batches if you're just starting out.
Standard lead time is around 15-20 working days after order confirmation, depending on current stock levels.
Yes, the SY-G055-1 comes with CE certification, and we'll supply the certificate along with the shipment.
The <1% frequency error applies to both air and bone conduction across their respective ranges, so you get consistent accuracy from 125Hz to 8000Hz for air and 250Hz to 6000Hz for bone.
Store it in a clean, dry place within the 10°C to 35°C operating temperature range, and keep the earphones and bone conductor in their protective case when not in use.
