Unboxing the Monoprice Desktop Headphone Amp (PID 11567)

We have a brand new detailed unboxing post for you today! I purchased this with mine own money (that’s a GRRM-ism) when it was on sale at the Monoprice website. It is the Monoprice Desktop Headphone DAC/amp, with the unceremonious model name number of 11567. PID is just Product ID, it is not part of the name 🙂

The unboxing post below is in timeline order. We start with a sealed box and proceed to remove things out of boxes. Because there are many boxes 🙂 Opinion on how it performs and other measurements (weight, cable length, etc) will be in the upcoming review. Please feel free to yell at me if it doesn’t get posted in the future 🙂

On the pictures: please forgive the “potato pictures”. If I wait until I can take perfect pictures, nothing will ever get done and posted 🙂 I am using a lighting contraption with an LED light strip up top ~ you see that in the second picture below. I left it in the picture so you’ll know it’s that ~ you see parts of it in some of the other pictures below that may appear strange and out of the blue 🙂

This Week in Headphoolia #17: Sony Z1R measurefefe (up to 6/17/17)

Another week is in the books, and we have another This Week In Headphoolia round-up. Speaking of round-ups, Father’s Day is always a good time for headphone sales. We rounded up some of them


Headfi published their Sony MDR-Z1R measurements using their own setup powered by GRAS and Audio Precision, and their measurements are noticably different from the Innerfidelity measurements and Tyll discusses the differences at IF.

One next possible step is for the two to exchange headphones and measure them with their own setups. This could partially help resolve the question as to whether the two headphones measured are different, or the difference is in the measurement setups.


Often the price (and relative price) of a consumer good is assumed to have some correlation to the product’s quality. But that’s not always the case. This varies from product category to product category, but needless to say, it’s almost never a linear correlation, audio or not.

List of Smartphones Without a 3.5mm Headphone Jack

Even the best of futurists sometimes have a hard time beating a coin toss with their predictions, so I have no way of knowing where the headphone jack will be in five or ten or twenty or thirty years from now. At the moment however, it reigns supreme in smartphones, despite some high profile defectors to the Lightning cable (Apple) and USB-C (a few Android models).

Given the situation today, it is a lot easier to keep track of the smartphones that do not have a 3.5mm headphone jack, rather than keep track of all the ones that do (the vast majority of them). There is only a handful of defectors so far. 2016 created a mini panic, but as of mid 2017, the existential crisis that was predicted did not materialize.

Samsung’s Galaxy 8 co-flagships along with the LG G6 and Sony XZ*, Huawei P10 flagships continued to embrace the headphone jack. Heck, even the brand new iPad Pro 10.5″ has a headphone jack 🙂 But the year is not over yet, we are still waiting for the new Note 8, LG V30, Pixel 2, iPhone 8, Moto Z flagships.

LATEST UPDATE: June 14 in 2017 ~ the companies are listed in alphabetical order. Under each company, the smartphones are listed in reverse chronological order (most recent first)…

+ three days of coverage of the Los Angeles Audio Show at Stereophile

The videos in this segment compare and contrast open versus closed headphones. Before you scream “apples vs oranges”, note that one can compare anything with anything ~ as long as one understands what they are comparing 🙂
