1. Can I change the cable on HPS1 headphones?
Yes, you can use any dual 2.5mm jack headphones ready cable to connect them.
2. What's the difference in sound quality with or without pillow?
The quality of audio on headphones is not affected if you use dedicated headphone amplifier. If you use a signal splitter than the sound is affected. The main affect is a lower volume at the same settings. Psychoacoustically the sound with BSE pillow is much reacher, extended to the low end.
3. How flat are HPS1 studio headphones?
We designed earcups acoustics based on the science of sound with many trial and error prototypes. The design is now fully rounded earcups that makes as little sound waves bounces as possible. It's a fully balanced acoustic chamber. Together with studio grade driver we achieve a flat frequency response. The sound is rich from low to hi notes. We followed the IEC 61672:2003 (BS EN 61672-1:2003 ) A weighted standard as closely as we can and reference by ear with industry standard HD650 and DT 770's. Our HPS is a mix of both this products.
4. Can I use the pillow on any amplifier?
Yes, you can connect the pillow as a subwoofer speaker to any amplifier. Just be careful with specs limitations. So if you have an amplifier you can use bridged to mono or simply a left channell to power the tactile pillow. But we do recommedn you buy a BSE pillow with our recommended amplifier. The transducer in a pillow is 35W at 8Ohm. Note this.
5. Does the headphones come with an amplifier?
No, we don't sell headphones preamplifiers with the headphoines. You can use them on any source - from I pod, pad, PC, sound cards, phones etc,... It's a standard 3.5mm or 6.3mm jack input. (TRS) If you use it with the pillow you have to split the signal in case you only have one output available.
6.Why are headphones earcps made of wood?
Wood is a go to material for any acoustic instrument. From pianos to guitars. Headphones benefit greatly from the use of acoustic materials. Plastic is used by other brands just to cut costs and shorten the production cycle. Wood is way better choice. And yes, it looks better!
7.If my amplifier does not have a low pass filter, can I still use it?
Yes. BSE pillow can reproduce more than just 80Hz. With higher frequencies the pillow will act as a membrane and vibrations will become airborne. Meaning you will have more sound leakage into your environment. At the same time you will feel wider frequency range and that could be of use in some studio scenarios. For example mixing upright bass, male vocals etc.
8.Are there any costs with signing up for a test drive?
Very little. We send you our gear and if you like it and want to buy it, there's no cost for testing. You simply pay for it and keep it. If you just want to test it and are not sure of buying just yet you have to pay for standard shipment costs from your country to the next tester. This costs vary but are aprox 20€ for EU and about $30 in US. If the cost of sending in to the next tester is higher than the cost of sending it back to OLLO, than you can send it back to our headquarters in EU. Agreed case by case.
