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.

Effective but may be uncomfortable
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I have eczema on my feet and use a prescription cream that I leave on overnight. I often have a problem sleeping in socks but the silicone feels cool on my feet. The only drawback I have is the opening of the socks feel very tight around my ankles making them uncomfortable on me. I wish the opening was a bit more flexible.

Burned my already sensitive feet, too big
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
Feels icky, and the heat gets trapped and literally felt like my feet were being burned by these. The bottoms of these feel prickly and they are way too big. You have to sit still and cannot walk in them.

Just as good as paraffin wax
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I might prefer these socks over paraffin wax. They are comfy and very moisturizing. I use these socks once a week to keep the heels and soles of my feet moisturized between pedicures. I rinse with warm, soapy water then hang to dry. They are hard to walk in, but there's a saying printed in the socks that's says something to the effect of "take a break, stay off your feet" lol I love that as a reminder to put my feet up and relax

Love these!
Color: Pink & Beige, Size: Small(fits up to size 7)
Love these! As I write this review, I’m sitting in my recliner with these on. I have had other silicone socks in the past and would like to share a few of the things that I have learned. These fit great! The others were 2-3 sizes too big because you could not order a size. I wear a size 7 women’s shoe. I got the smaller size. I walked around my apartment in my old ones and they got kinda yucky. Now, I sit in my recliner, put them on and chill for a few hours. I now take them off and put in a ziplock bag so they stay nice and clean (no cat hair!). I use them once a week usually on Saturday or Sunday as I’m a working girl. Also, I use Auqaphor before I put them on and put cotton socks on after I’m finished. Your feet will be SO soft. This is not a one and done…I do this every week especially during sandal season! I know this was lengthy and I hope you got some tips.

The answer to calloused feet.
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
If you have dry callused soles, these are your answer. All my calluses left and my feet were very soft. They should not be walked in unless you are very, very careful as you will slip and fall. I stopped using them for a while and all my problem calluses are back, even when I use lotion at night. They tell you not to sleep in them, I don't know why. I do put these on at night and end up taking them off later as they're not comfortable to sleep in.
