ONEsurround, the World’s only wireless surround without any power cord or speaker cable, is a tremendous breakthrough in surround system. Wireless system gives freedom of placement and storage. You can simply setup in a minute. Technically, wireless system can eliminate cable distortion and save cable cost.
Satellite speakers are battery operated. We maximize battery usage so that they can play loud sound and can have 100 hours play time. You don’t need to worry about charging.
An all-in-one firmware is loaded in a high integrated single chip, giving the shortest signal path and the simplest hardware. Video and audio are perfectly synchronized as our wireless speakers can perform on different channels at the same time with low latency and zero time slip between channels.
ONEsurround kit goes with a compact and powerful subwoofer. It is a twin driver design in a sealed enclosure. It delivers not only powerful, but also clear, fast and punchy bass. The ONEwoofer.6+6 can reproduce deep bass down to 30Hz, surpassing a ported 10” subwoofer. The ONEwoofer.8+8 can cover up to 50m2 room.

Today, none of the technology available can do true wireless surround because they lack the 2 prerequisites:
low power consumption allowing operation by batteries, and synchronized multi-channel transmission from source to satellite speakers
Bluetooth does not support multi channels and only works on a single channel carrying both L+R sound track simultaneously.
WiFi is poor in channel synchronization because the satellite speakers receive the sound tracks in sequence, resulting in delays among speakers and easily interfered by other signals (other WiFi devices) in the process, which further worsens the misaligned channel problem.
WiSA consumes high electric current, therefore cannot be operated on battery.
ONEaudio DECT technology surround system can do true wireless surround because:
DECT supports 6-channel concurrent broadcast
DECT is intrinsically accurate in timing and achieves channel synchronization within 0.5uS
Ultra low current consumption, 1/10 of WiFi and 1/20 of WiSA speaker - ONEmicro can play songs for 20 hours at normal volume or 5 movies at high volume
DECT technology can produce high-fidelity sound which is conducive to an outstanding surround experience
We have overcome deep-rooted problems :
Cable stray capacitance and inductance cause signal distortion, phase noise and destroy frequency response linearity. The longer the cable, the worse the distortion.
Our solution : ONEmicro is a wireless speaker, no speaker cable means no cable distortion.
Speaker drivers not in phase due to passive crossover circuit inside speaker
The out-of-phase problem destroys sound clarity. Unclear sound, especially blurs in the middle-range frequency, will be multiplied in surround sound playing when the satellite speakers play at the same time. That is why you would suffer from ear fatigue after watching a film.
Our solution : We use DECT technology and DSP technique, all speaker drivers are guaranteed in-phase and synchronized.
Shared supply power among amplifiers dampening sound effect
Manufacturers of AV amplifiers usually claim a high power for each channel. But that’s true only when talking about an individual channel. However, when 5 channels play loud sounds simultaneously, the power supply is shared among all amplifiers. The weakened power supply will clip the sound in highly dynamic loud sound play and dampen the exciting feel. This distorted sound will also become annoyance to the ears, especially after prolonged listening.
Our solution : Each speaker has its own high-capacity battery. No sharing of power supply ensures solid and vigorous sounds.
Manufacturer tend to use low-cost ported subwoofer in home surround system. Ported subwoofer has non-linear group delay and non-flat frequency response. Subwoofer is seldom designed to match with the satellite speakers, sound spectrum may overlap or become gaped.
Our solution : As good sound quality is of utmost concern, we have used in ONEwoofer a sealed enclosure design for a wide and linear frequency response and twin speaker drivers for powerful bass. ONEaudio surround has been created on the concept of an integrated system with components fully matched to each other for authentic surround sound.
Lack of flexibility in speaker placement
Good speaker placement is essential for the best surround sound effect. Current surround system requires planned wiring, usually tying in with a house renovation, making it difficult or impossible for subsequent readjustment to refine the surround effect. Or, the speakers could not optimally be placed as restricted by the layout of the place (e.g. the rear speakers installed at the ceiling).
Our solution : True wireless and compact size speakers promises ideal placement, and can be stowed away when not in use.
Poor vocal sound due to low quality amplifier and speaker to cut material cost
A surround system consists of 5 amplifiers, 5 speakers, 5 speaker cables and a subwoofer, a low-price surround system cannot afford qualitative materials to be used.
Our solution : We have invested more than 5 years in developing (i) an all-in-one firmware for loading on a single chip and (ii) a simple hardware design with minimal passive components. The saving in hardware cost is devoted to the high-quality speaker driver. The diligent software and hardware design is the key for ONEaudio products’ extraordinary performance at a low price.
Only DECT technology can do true wireless surround
Triple buffering, optimize each layer buffer, shorten latency
We use spread buffering technique to minimize latency. Each layer software are fine-tuned to the shortest buffer size, enough to overcome data jitter but didn’t induce long delay. We built each signal processing software module, make sure signal path is straight through and is well controlled. Together with RF protocol and decoder delay, total latency is 60mS, you never find sound lagging.
Separated speakers vs sound bar: is sound bar for genuine surround entertainment ?
Some people like sound bars because of its low price and simple setup, and because of this, are prepared to accept the mediocre surround sound effect of sound bars. We strive for the same advantages as sound bars but are not willing to compromise on sound quality. Sound bar is only a TV built-in speaker upgrade version. It never gives you a life-like three-dimensional soundscape. The ONEmicro 5.1 surround speaker system, consisting of individual front, center, rear speakers and a subwoofer, gives far more than a sound bar does.
Sound bar: closely-packed speakers within a narrow enclosure
The sound bar has very poor channel separation. Left and right channels got mixed up inside the sound bar enclosure.
Rear sound effect is created by sound reflection of side speakers in the sound bar, leading to sound divergence and hampering the 3D effect.
Slim-size sound bar does not provide sufficient acoustic chamber size to generate mid to low bass. To compensate for this, sound bar manufacturers commonly use equalizers which would impair the sound quality and even make the sound unbalanced.
Each pair of ONEmicro has its own responsibilities and definite channel separation. Sound comes from every direction, creating a 3D life-like surround sound space. To deal with the lack of mid-bass commonly found in small-size speakers, we have developed a bass-filling technique (see next section) by a uniquely designed wide frequency range subwoofer to fill up mid-bass. ONEmicro is a well-balanced speaker dispensing with the need for equalizers, the sound is therefore real and natural.
