Frequently Asked Questions:

What is included in the price I pay?
  • The HUM Pristine (along with whatever customisations you may have selected)
  • Included accessories (earwax removal tool, case and stock cable)
  • 1st set of ear impressions (ear moulds) done at our partnering audiologist, The Hearing Centre
  • All shipping costs involved for the transport of your ear impressions to HUM and your HUM Pristine to us
  • Shipping costs of sending your product back to HUM for refits/repairs
What is NOT included in the price I pay?
  • Premium customisation options
  • Subsequent sets of ear impressions done for any refits should it be required, even if the error is on the audiologist's side.
  • Repair costs for damages not covered by HUM
Are there any hidden costs that have not been reflected in the price I pay?

Apart from the points listed above, NO! As mentioned above, the cost of ear impressions and shipping will not be factored in as an additional, hidden cost. It our goal to be as transparent with regards to the price you pay for your HUM Pristine.

How long will I have to wait before my HUM Pristine are ready for collection?

You’ll have to wait for 6-10 weeks. This includes the building time of 4-8 weeks, as well as shipping time of 2 weeks to and fro HUM.

How long is the warranty for my HUM Pristine?

HUM warrants your Pristine from manufacturing defects for a period of 1 years. There is a 30 day warranty against fit issues.

Why 2 unit 2-way crossover?
The cavity in our ears are not large enough to accommodate a phase favorable crossover even if it is a 2 units 2-way design. Adding more drivers would just overlap the frequency response range that could be easily handled by 2 drivers or less, therefore, phase would be mixed up due to the lag between different drivers. Inevitably, interference occurs, boosting unwanted signals or cancelling certain signals which leads to unwanted noise and loss of detail.

Having more drivers in an in-ear monitor increases mismatching of drivers. Driver matching is always necessary and having more drivers tends to lead to a larger difference between L/R channels resulting from the presence of more electronic components i.e. resistors, and drivers may not be perfectly volume matched. Soldering, and uncertainty in manufacturing tolerances of other components also contributes to unmatched frequency response.

While a smooth frequency response curve may not guarantee good sound quality, it will point out that the product doesn't have flaws.

In the case of the HUM Pristine, less may be more..

Why not ceramic capacitors?

The performance of a ceramic capacitor is affected by temperature, voltage and frequency. It is common for the capacitance to decrease by 10-20% over time, which is fatal to the performance of its original role, which is the cutting off of frequencies. Despite higher costs, film and electrolytic capacitors are always a superior choice, where good temperature stability and AC response are always guaranteed.

Why don't HUM use WIMA capacitors?

This is a common question from audiophiles. We have tried almost all available capacitors, but WIMA doesn’t perform well (low profile series) on crossover application, whereas MKP10 can’t be inserted into the earphone.

What kinds of electrolytic capacitor is Pristine using? ELNA/Nichicon/Rubycon?

While there are hundreds of electrolytic capacitors that fits our requirements, many of them sounds weird, including some high grade 'audiophiles series' products. We removed the sleeves of capacitors to keep it confidential, and as long as it performs well and works, why care?

Does the 99.99% copper hooked wire really affect the sound so much? It’s very short.

Anything in the signal path including solder, connectors and IEM cables do, so of course the internal wires makes a difference!

Why Amphenol MMCX connectors, and not molex/emerson/ etc.?

After countless of comparisons, connectors made by Amphenol sounds better.
