Brain Tuners are based on brain wave studies using electroencephalography (EEG) technology to map different states of consciousness known as Delta, Theta, Alpha, and Beta. Delta is associated with deep sleep. Theta is associated with meditation and dream states. Alpha is associated with relaxed awareness, creativity, and heightened learning. Beta is associated with high alertness and focus.

When the Brain Tuners are simultaneously sounded – one in the left ear and the other in the right ear – the two hemispheres of the brain function together to integrate the two sounds, creating a third, different tone called a binaural beat. When the Fundamental Brain Tuner tuning fork is sounded with a Delta, Theta, Alpha, or Beta tuning fork the difference between the two tuning forks creates a binaural beat which is heard as a pulsation. The binaural beat gently signals the brain to shift into a different state of consciousness.

When we go through a 24-hour cycle, we shift into different states of consciousness determined by our life requirements. One can visualize a car that shifts into different gears as necessary to meet the requirements of the road, i.e. a low gear for pick up and climbing hills, a medium gear for slow driving, and a high gear for highway cruising. In a similar way, living our life requires shifting into “different gears” for different situations.

What are the Brain Wave States?

Beta

Beta state is associated with peak concentration, heightened alertness, hand-eye coordination, and visual acuity.

  • Peak-concentration
  • Heightened alertness
  • Cognition
  • Visual acuity

Alpha

Alpha state is a place of deep relaxation, but not quite a meditation. In Alpha, we begin to access the wealth of creativity that lies just below our conscious awareness – it is the gateway, the entry point that leads into deeper states of consciousness.

  • Relaxation
  • Quietly Alert
  • Introspective
  • Creativity
  • Visualization

Theta

Theta is known as the twilight state which we normally only experience fleetingly as we rise up out of the depths of delta upon waking or drifting off to sleep. In Theta, we are in a waking dream, vivid imagery flashes before the mind’s eye and we are receptive to information beyond our normal conscious awareness. Theta has also been identified as the gateway to learning a memory.

  • Waking-dream
  • Vivid imagery
  • Meditation
  • Memory
  • Intuition

Delta

Delta is associated with deep sleep and long trains of thoughts about nothingness or energy without form. During delta, we plug into our source, the Universal Energy Field, and use the energy to revitalize our mind and body.

  • Detached Awareness
  • Healing
  • Deep Sleep
    Using the Brain Tuners

    The Knee Tap Technique

    1. The method for sounding the Brain Tuners is called “the knee tap”:
    2. Hold your tuning forks by the stems with moderate pressure – not to tight and not to lose. Do not hold your tuning forks by the prongs because the prongs need to vibrate in order to create the sound.
    3. Gently tap the flat side of the tuning fork on your knee cap. Do not hit your kneecap. All it takes is a gentle firm tap and your tuning fork will sound.
    4. It is best to tap the Fundamental Brain Tuner on one knee and then the Delta, Theta, Alpha, or Beta Brain Tuner the other knee.
    5. Bring the forks slowly to your ears, about 3 to six inches from your ear canal, and listen to the sounds.
    6. Shifting your State of Consciousness
    7. Once you have mastered the knee tap method then tune into your current state of consciousness. Follow these steps:
    8. Consult the chart above and ask yourself what state of consciousness you would like to shift into.
    9. Select the Fundamental Brain Tuner and the Brain Tuner that matches the state of consciousness you want.
    10. Holding the Brain Tuners in your hands ready to tap, visualize and/or remember a positive experience for the state of consciousness you want.
    11. Tap the Brain Tuners and listen to the pulsation. Let go and allow yourself to shift.
    12. When the sound fades, switch the tuning forks in your hands and tap them again. Enjoy!

    Great Instructions, Straightforward Assembly
    Color: Black
    I just received this chair today, so my product review is mostly on the packaging, instructions, and assembly. The product was well-packaged, and it was obvious when I unboxed it that a lot of care and thought went into packing it in the most efficient way that would also protect the parts. I was positively impressed with the packaging. I was also incredibly impressed with the instructions and assembly process. I am used to cheaper products where the parts only half fit or important components are missing, or where the instructions were confusing and unclear. This chair's instruction manual was very clear and concise. The diagrams were easy to understand and neat. The screws came labeled and separated and also included the scew types and sizes/lengths, which is handy in case you need to pick up extras at a store somewhere. But they also included one extra of each type of screw, washer, and cover, which I appreciated during assembly. (I didn't find myself worrying what would happen if I dropped a screw, which is something I would normally be distsracted by while working.) The only things I would take points off for were these: 1. The instructions said the chair came with gloves for assembly, but no gloves were included. That was fine with me, but why mention them if you won't include them? The instructions even later say not to use the chair if not all components were present...but all the important ones were, so I assembled it without gloves (as I probably would have done anyway, since it was for me and not another person). 2. It matters which side of the seat is the front, but the sticker was confusing. The instructions show a sticker placed on the side that is the front, and that is where my sticker was placed. However, the sticker says "FRONT" and has an arrow pointing somewhere. In the instructions this arrow pointed to the front. On my seat, however, the arrow pointed to the back. So am I supposed to believe the sticker placement (it was diagonal, so it looked haphazardly slapped on) or the arrow? On that particular step the piece you are screwing into the seat can fit both ways, but thankfully there is a later step where it becomes obvious which side is the front vs. the back. (The arm rests can only be attached to the back.) So I wish that had been clearer up front, but otherwise it was okay. Recommendations for assembly: - To attach the wheels, apply firm, direct, straight-down pressure. I tried screwing them on at first but you just push. Make sure they go in the whole way like the picture shows. - When they say to tighten the screws to only 60%, it's a helpful tip, because you can't fit the armrests on both the seat and chairback at the same time with the screws completely tightened. Just tighten them enough to fit the pieces on, then later you can tighten up the screws. So far I find the chair to be very comfortable and I'm exceedingly happy with it. The lumbar support seems like it could potentially be a little chafy or scratchy, but I'll give the chair a chance before deciding if it's problematic or not. Like I said, I only got the chair today, so I can't speak much to its long-term comfort, durability, or longevity. But I was so impressed with how easy and straightforward they made the assembly that I had to write a review to show my appreciation.

    It's okay
    Color: Black
    Appeared to be a super comfortable chair. Purchased for my mother to work from home and the material is apparently slightly itchy and the arm rest isn't quite comfortable. It was pretty simple to put together but it did take some time.

    An Actual Nice Chair for a Decent Price. +2 for the Tool.
    Color: Black Grey
    Welp, My old chair finally broke, so It was time for a new one. I ended up coming across this chair here, and I couldn't really find anyone talking about it online. I decided to give it a shot since it was on a good sale for Christmas, going down to 99$. I'm going to be honest, I am pleasantly surprised. The cushioning for it is a little firm, but that is perfect for me. Its pretty average when it comes to office chairs, but having the added lower back support is a great touch. I have no complaints about it. The one thing that I am actually really happy about isn't on the chair. Don't get me wrong, over the week I have been using it, It has been nothing but great. That thing is the actual tool it came with. Its a basic Allen key, but the top of it is a molded handle instead of a "L" piece of metal. It made the already easy process of putting together this chair even better. Even after this chair has ran its course like all other chairs, I'm going to still use this tool. So yeah, I think 5 - stars pretty accurately describes how I feel about my chair.

    Comfortable chair that works great for long hours
    Color: Black
    I’ve been using this office chair for a few days and it’s been very comfortable for working and longer desk sessions. The high back design and ergonomic support help maintain good posture, while the cushioning stays comfortable throughout the day. The chair feels sturdy and stable, and the 330 lb capacity gives it a solid, durable feel. It also rolls smoothly and quietly, which is nice when moving around the workspace without creating a lot of noise. Overall, it was easy to assemble, looks professional, and offers great value for the money.

    Very Comfortable Ergonomic Chair - Great for Long Work Days!
    Color: Black, Color: Black
    I’ve been using this ergonomic office chair for a couple of weeks now and I’m genuinely impressed. For the price, it offers excellent comfort and support. What I like: • Very comfortable padded seat and backrest — I can sit for 8+ hours without back pain. • Good lumbar support and adjustable height/armrests. • Holds up to 330 lbs easily (I’m 240 lbs and it feels very stable). • Smooth rolling wheels and sturdy base. • Easy to assemble (took about 20 minutes). The mesh back breathes well and doesn’t get hot. It looks professional in my home office too. Overall, this is a solid ergonomic chair. If you spend a lot of time at a desk, I highly recommend it. Would I buy it again? Yes, definitely.
