Noticed a very loud shriek from the phone (S7e) speaker while the DFB is connected and a call is received (ringing)
 
Is that a known issue? how to resolve that?
 
Thanks

Happens to me, only music comes through the headphones, not the system sound which still seems to come out of the phone speaker. Not really a concern for me (I'm using a std S7)

I'm interested in the Dragonfly Red, but have 2 questions:
 
1: Has anybody used one with a Chomebook? I'm assuming it would work, but I'd like confirmation
 
2: Does it have plenty of power for the AKG Q701?

 

[pinoyman]

1. it will work.
2. not enough power to drive even the K701. MOJO can however. 
but can drive most iems.

I'm not spending that much, isn't the MOJO like 3 times the price?
 
I don't listen that loudly. The headphone jack on my Acer Chromebook R11 has plenty of power to get the Q701 sounding good. I find it hard to believe it wouldn't have more power than my Chromebook's headphone jack. You've heard the Q701 with the Dragonfly red?

Um, are you sure about #2....

DFR will drive AKG K7XX to rediculous, deaf inducing levels at less than 1/2 volume on UAPP on my Samsung Tablet. On laptop, you only really need to use about 30% volume for the DFR and 10% on foobar2k slider in system volume mixer....if you do 100% on the DFR you would need like 3-4% on the F2k slider in volume mixer. With my Fostex TH-X00 Purplehearts I'm using 19% for the DFR and 6% foobar2k on system mixer on my laptop. Absolutely plenty of power to drive AKG' K7XX, and drives Fostex T50RP Mark III EASILY too...

Sounds good. I may get one in the future.

The DFR can apparently drive HD600's too. Is the 701 really that much harder to drive? I don't think so...

DFR powers my Q701 and T50rp mk3 without issue. Both reach deafening levels.

Red has enough power to drive my Q701 perfectly. Q701 sounds a little better (or different probably is a better word) with mojo though, but not 3x better - it is all in some details/nuances. I had mojo and returned it since I listen mostly to IEM (Westone UM pro 50) and df red does the job very well.

Even the DFB will send my K702 to a volume level higher than I could safely listen so the DFB should certainly be OK with the K701.

I generally have the DFB volume set at 20/44 so a little under 50% (generally listening to jazz), it may go a little higher for quiet classical pieces but never even close to max.

I use my DFB with my Chromebook (Acer C720), the only problem I find with the Chromebook is that the volume control jumps in 2% steps so fine control is difficult. I have my Chromebook in Dev mode so use Alsamixer to get fine single step volume control. I can see no reason why the DFR would be any different.

  iPhone 7 users, here's a workaround to listen & charge at the same time. This is an Apple made adapter. 
 

 

 
This adapter is also said to be necessary to avoid clicking noises.
 
Are you kidding? This simply Looks HORRIBLE!

Does anyone have RMAA measurment of DF Red/Black ??

 

[Epiteto]

I'm thinking about to sell my fiio x1 to buy a black dragon fly to connect via otg to my zenfone
Do you think dragon fly black, is better than a fiio x1 dap?
Thank you

To better qualify my statement using an Objective 2 amp as reference:

O2>M-100 - 7-8 o'clock on low gain
DFR>M-100 - 35-45% software volume (varies depending on song/player)

O2>Q701 - 10-11 o'clock on low gain
DFR>Q701 - 40-60% software volume (varies depending on song/player)

O2>T50rp mk3 - 1-2 o'clock on low gain
DFR>T50rp mk3 - 70-85% software volume
(varies depending on song/player)
