The world's first high performance full balanced discrete class A headphone amplifier by Eleven Audio TM combines smooth detailed sound with the noise free black backgrounds. Amazing low level detail, smooth very real mids and vocals, and clear highs only begin to describe how good this amp is!

Internal user replaceable batteries dramatically reduce AC line noise to negligible levels. This amp will run for hours without AC power, or plug in for continuous play, with the same highly refined sound on either power source. Circuitry is designed to float the batteries on the mains at all times for pure clean sound.

Accepts only balanced XLR L/R channel inputs. Four channels of amplification straight through to a high performance balanced headphone connection with 1.5 full watts of super smooth sounding class A bias amplification. DC coupled means huge low frequency bass resolution, the Broadway sounds way larger than it looks and can drive nearly any power hungry headphone with ease.

Specifications:

  • Frequency Response: DC-100 KHz
  • Power: 1.5 watts @ 32 ohms fully balanced class A operation (amplifier biased full on at all times, no edgy crossover distortion typical of other amplifiers)
  • Signal to noise ratio 130 dB
  • Run time: Approx. 6 hours on full battery, indefinitely while connected to the external AC power supply
  • Inputs: Stereo balanced 3 pin XLR's only
  • High quality volume adjust potentiometer
  • Headphone Outputs: 4 pin balanced XLR and 4.4 mm Pentaconn
  • Batteries: Replaceable Li Ion 18650 x 4 batteries add to power supply filtering
  • AC Charge adaptor: 100-240 VAC, 50-60 Hz. (Unit has built-in battery management, auto-off on low battery, auto charge). Requires a standard grounded IEC C13 style AC cord (not included)
  • Dimension: 8.3 in W x 6.1 in D (plus volume knob) (212 mm L x 156 mm D, 190 mm including volume control), 1.9in / 48 mm H

Orange looking, but large capacity
Size: One Size, Color: Brown
I ended up returning this product, it looks more orange in color than what is pictured. Also, it doesn't smell like leather. On a positive note, it was inexpensive and did have a large organization capacity.

Best wallet on the market.
Size: One Size, Color: Nubuck Black, Size: One Size, Color: Nubuck Black
This is the only wallet I buy now. Over and over. I like simple wallets. No bifold. Trifolds hurt your back. Hard case are a mess that rub your credit card mag strips off from friction. I found this a few years back and have bought 3. I am a stone worker so mine get worn from the dust and grit in my pockets faster than normal wear and I need to swap them out every couple of years. I like the simplicity and the fact that the pockets are stitched the same depth so your cards stack like varying length stair-style tabs rather than all the same depth. Wallet is RDIF protection lined. I can put like 15 cards in this wallet and it’s still thinner than a bifold holding 5. I love it. I mean it. I haven’t found a better wallet than this one. They are very well-built. Picture shows wallet with 19 cards + 40 dollars. 3/4 of an inch thick.

Good Product
Size: One Size, Color: Smooth Finish Black
Good product although the leather is a bit stiff. Hopefully it will soften up over time. Fair price, fast shipping…

So far happy.
Size: One Size, Color: Glossy Nappa Black
As everyone has made clear, it holds credit cards very tight. Almost 3 weeks in & mine seems to be breaking in a little, but cards are still a bit difficult to remove. No complaints with money clip. One thing I thought was a dumb move on manufacturers part, was inside one of the card slots is a tag sewn into the seem. This makes things alot worse while trying to fit cards into all slots. The tag will catch on the cards & bunch up in the corner of the slot making things even tighter in that slot, plus all slots surrounding it. I was able to get a scissors in there enough to cut most of the tag out, without cutting the stitching itself....it made a big difference....enough to fit an extra card in & without it bulging up the wallet overall. Why would they feel it necessary to do this is beyond my pay grade. Its not like you can even see what the tag says until you cut it out.... I believe it was the name & logo....but Jesus, how unnecessary, & in the dumbest place one could possibly think of. Especially when EVERYONE comments on how excessively tight it is to fit cards in the slots & also be able to retrieve them with relative ease when needed. Overall I am happy with this wallet so far.... I'll be interested to see if it holds together over the long haul or if the stitching gives out in a year & has to be replaced. I will update this review as time progresses. UPDATE: Its almost to March 27 2023 & its been holding up great. No ripping or tearing stitching holding strong. Still holds cards really tight, but they are easier to remove.
