Heritage Audio has changed the game of headphone amplification with its revolutionary O.H.M. Amp, the first of its kind to offer a combination of impedance-matching amplification, three independently selectable input sources, and both 6.35mm and 3.5mm built-in jack connections to ensure you receive the highest level of sonic performance from your headphones. Whether you rock top-of-the-line cans or budget-friendly buds, this amp houses the necessary components for dynamic, crystal clear audio, including the discrete diamond buffers commonly found on Heritage Audio’s high-end R.A.M. System models, Burr-Brown op-amps for ultra-low distortion and high-fidelity audio performance, and the coveted Alps “Blue Velvet” potentiometer that gives all audiophiles full control over their output levels. As if the O.H.M. Amp wasn’t already bursting with top-notch sonic aptitude, Heritage Audio also included a thru output that allows for chaining options or Bluetooth receiver capability and a 30-volt power supply to provide dynamic range, adequate signal-to-noise ratio, and strong power delivery with low distortion at any impedance. A true trailblazer in the audio sphere, Heritage Audio’s O.H.M. Amp will push your headphones to their optimal performance level and deliver an exceptional listening experience.

Innovation at its core

Heritage Audio’s O.H.M. Amp is built around three foundational components to support your headphones in achieving peak sonic production: First, the O.H.M. Amp offers three top-quality, independent input sources — a balanced input, a gold-plated unbalanced RCA input, and a Bluetooth receiver with Burr-Brown DAC. It then allows you to dial in the impedance level that best matches your particular headphones, with a range beginning at “low” impedance output and capping at 600 ohms. Lastly, the O.H.M. Amp includes two independent 6.35mm and 3.5mm jack connections for your headphones, meaning that you can ditch those noisy, staticky third-party adapters in favor of direct audio bliss.

It's a good one, buy it.
Size: 16 AWG-100 ft
Actual 5 stars! OFC, copper stranded wire, takes solder nicely when tinned, stiff and pliable enough to stay bent. covering melts INTO wire as expected. I was hoping for a good deal and got one.

Not bad for money. But the spot lens is def a narrow spot
Color: 4.5inch Spot Light, Color: 4.5inch Spot Light
I did a direct comparison to BD squadron pro with spot lens. Pic one is 1 squadron spot lens, pic two is 1 auxbeam 4.5 Not a pair. Only one light each. Then the video is 2 squadron pro one with spot lenses the other with combo lens. Then both auxbeam 4.5. I wouldn’t buy the spot lens unless you have other lights or just trying to light a narrow beam a long ways. The fill light is not good. I say the brackets and the finish is on par with BD, not as deep as the XL80 but similar in size. The BD XL pro is def brighter with better fill even with spot lenses. I would say 4 of these would match the XL Pro at half the money if you have the space for four of them. But even 4 don’t match the XL80’s. But for 160 bucks it’s a good solid light.

Great quality, and very bright.
Color: 4inch Spot Light, Color: 4inch Spot Light
I installed 4 of these pod lights in the front bumper of my 2009 f150 (2 spot beam, and 2 combo beam), and I am very pleased with the overall build quality, and brightness of these pod lights. Installing them is fairly straight forward once you have them mounted where you want them, and they look great! I highly recommend these lights if you are looking to upgrade the lighting on your vehicle! The video I have attached is with the amber lens, and the picture with the lights on is without the lens. I prefer to keep the lenses on most of the time since it does add a layer of protection from the sun, and bugs/rocks while driving. I also do prefer the amber color for driving at night compared to the white.
