Are you serious? Just my luck bro!!
@Tumyum According to John you can control the volume with your phone.

When a device, such as a USB DAC, is connected to any host, in this case a Google Pixel phone, a process called enumeration takes place between the host (Pixel) and peripheral (USB DAC). According to Google's own documentation, enumeration is, "The process of detecting which peripherals are connected to the bus, and querying their properties..." In layman's terms this is a conversation between the phone and DAC, that enables the phone to determine the capabilities of the DAC. A standard enumeration would identify for the host, what sample rates the DAC supports, its power requirements, and the DAC's default and maximum volume levels (if the DAC has volume control).
Enumerating the volume level is where many Android phones don't follow the agreed upon standards. Keep in mind that some Android device manufacturers and third party app developers have solved this issue. Google, as the creator of the operating system, has elected to not solve the problem. In this specific case, when the DragonFly Red is connected to the Google Pixel phone, the DragonFly tells the Pixel that its default volume is 41. The DragonFly Red has a 64 step digital volume control that defaults to step 41, so as not to ruin ears or equipment when it's initially connected. In its infinite wisdom, Android reads this default volume setting as the DragonFly's maximum volume. Thus, there's no going over step 41 out of 64 when turning up the volume.
Digging deeper into this issue, reveals a larger issue. When Android adjusts the volume of the DragonFly or any other USB DAC, it's doing so in software, not the DAC's built-in hardware volume control. You can see that the Pixel adjusts its volume from say 0% to 100%, but this is only working between step 0 and 41 in the DragonFly Red USB DC. First we have Android's inability to distinguish between a default volume and maximum volume upon enumeration, then we have Android's inability to operate a hardware volume control on a USB DAC. Both of these fairly simple and very standard items have been done for many years in OS X / macOS, Windows, Linux, and iOS. Android uses the extremely popular Advanced Linux Sound Architecture (ALSA) that is used by nearly every Linux-based audio device you and I have ever used. But, Google has elected to remove many capabilities in its version called tinyalsa. I can see sliming-down software to work on a phone, but stripping out what many consider essential was a frustrating move by Google.
As part of my research I contacted Google about this and another issue I'll discuss next. I received a fairly fast response and inquiry asking for additional information to pass along to the correct team member(s). I laid out the details of what was happening with lack of hardware volume control and the strange default / maximum volume issue. I received the following one sentence response, "We currently do not support enumeration and control of external volume controllers but we're continuing to extend our USB Audio support in future versions of Android."
My interest in using a official Google phone, with the official Android OS, has taken a serious hit. It's my understanding that a limited number of non-Google phones have heavily modified versions of Android than enable hardware volume control. However, most phone manufacturers don't enable hardware volume control.
It's entirely possible that AudioQuest could release a firmware update to set the default DragonFly Red volume to step 64 (maximum), but that opens another can of worms. AQ would be compensating for a shortcoming of Google, by introducing something it doesn't see as a best practice. given that Android has a 69% share of the mobile phone market, followed by 26% iOS, 2% Windows, and 2% Java, AudioQuest's hand may be forced by Google's lack of interest in making its operating system meet the standards that every other major OS has met for many years.
yes I'm absolutely sure you can have a volume control on your phone but it is of course dependant on the player apNope, I tried the Mojo with Poly at the show and I could NOT bypass the Mojo and just use my phone to increase the volume to any level I like. I love the idea of having the Mojo+Poly, put in my pocket, and forget about it. Just me and my phone like the old day! The Poly cannot just let me bypass the Mojo and control everything with my phone, including increase the volume on the Mojo. It made sense that by do this, the color marbles volume will change and I don't see how the Poly could do this. I hope I'm wrong and I love the idea, I did try but no luck.
John from Chord, are you sure??? You can control the volume with your phone and no need manually press the color marbles to increase the volume? Please clarify because I tried but no success but you said it could, I'm hoping that I'm wrong here.

Most fitness clubs, spin classes and weight rooms I've been to in past ten years have demographic under forty and therefore means members with less arterial plauque, less wear on joints. Socializing and acceptance within peer groups seems as important as actual exercise at this stage of life. After forty drop-off in fitness club memberships is big. Swimming has wide demographic as water provides buoyancy against gravity making exercise much easier on older joints. Unscientific observation is many American adults would rather watch activity (professional/college sports) than participate in exercise. Take-out food should be an infrequent treat and not a lifestyle diet. Thinking Atlanta, GA would lose five percent plus of state revenue if watching sports and buying takeout food were removed
The Poly is not available to purchase yet is it? I cannot find it online in the UK.
I cannot find the Poly for sale online anywhere.
I can see the Hugo2 online at Audio Sanctuary, but nowhere else.
It is as if CES 2017 has bypassed the attention of the HiFi trade. Maybe dealers will wake up in March, when volume production starts.
