    The HF3 sounds like an SR225 class level Grado stuck into wood cups. I'm using TTVJ pads.

    The GO Blu charges from both the high speed (USB C to C) and lower power (USB A to C) chargers.

    I could care less about U&M and dislike that they "own" the town (hey, many Universities are growth businesses) but here is something to annoy you.



    There's always Baylor in TX. Pay Harvard fees to get a non Harvard education. Wannabe USC. Should read the WSJ expose of Baylor marketing practices in getting people who cannot afford them into their school with massive parent loans.

    Not enough IMO. For portable, really need something more muscular like iFi Micro BL.

    I've had my unit for about a week now, love the sound, however if I have the unit connected over Bluetooth and in my pocket the audio begins to break up quite quickly. My main use case was to be able to listen to my wired iems while on a Google meet chat, I have a USB mic set for input and the go Blu set to output, if I have any other audio playing than the call itself then I have to reconnect the device before I can hear again.

    Anyone else that uses OS X able to try this out as well? I've updated to the latest firmware.

    Other than the flakey connection and the call usability, I'm quite impressed with this little device, battery life and output power are impressive.

    Thanks, now wondering if it can drive Katos properly. They are specced at 123db.

    Thanks a lot for your feedback. As for break ups, can you please try with another smarpthone if possible? This would help in finding out whether GO blu's receiver is the culprit or not.

    ^ this is truth. while the JVC-FDX1 sound ok from either a iFi Go B or a Shanling UP4, it's merely pedestrian. I use either unit with my FDX1 for the last 30 minutes of late night drone listening before sleep, but nothing with real resolution or instrument delineation.

    for fun, plugged in JVC FDX-1 into the iFi micro iDSD Signature, and wham - really comes to life~
    Eco mode with IEMatch completely off.
    sadly for my Campfire Audio IEMs the iFi Go B has hiss and air with Solaris 2020 and Vega 2020, whereas UP4 is dead black.
    be wise about what gets paired with iFi G blue.

    IIRC note: the iFi GO B delivers more power than Shanling UP4, about same power specs as UP5.

    These JVCs are rated at 103dB @1mW, so nothing crazy, but perhaps they need a lot to be fully awake.

    Hmm, this is tiny enough to be tucked inside a large earcup or perhaps in between a suspension headband and strap to make your own "wireless" headset. I sort of did this eons ago with a Fiio A1 and some random clip dap.

    Yes, that's possible indeed. I used to roll with Sansa Clip+ fixed to Koss Porta Pro some decade ago :D

    Thanks for getting back!
    While the range is slightly better with an Android phone, having the Blu go in my pocket or covering it with my hands seems to cause it to stutter.

    Understood and thanks. I'll ask internally about GO blu's arange, whether it can be improved via a firmware update.

    Long time lurker, haven't posted in a while. My Sanza clip + is going poop and the ifi GO blu caught my eye. LDAC is nice since I have it on my phone. I'm wondering if this could replace my clip + since it's no longer being manufactured.

    Sansa Fuze and Clip were great DAPs at the time, but it's good to know that you enjoy your GO blu. How much of a change it is for you btw.?

    I've had a Go blu for about 2 months. I bought it to have a convenient grab and go setup for walks and other casual listening. My typical setup for this is Galaxy S8 > BT > Blu > MD Starfield, which does the job nicely. Certainly nothing exciting either pro of con soundwise, probably exactly what one would expect from pairing the Starfields with a decent source. (I do not hear any hiss with this setup, but YMMV. I hate hiss, but my ears have significant mileage on them.)

    I recently got into a jam when I had to work remotely for a week away from my usual spots and had failed to pack my usual BT headset. But I had thrown the Blu and Starfields into my work computer bag. I knew that the Blu has a microphone but had dismissed this feature as "how could it possibly be any good". I'm pleased to say that the Blu's microphone worked just fine, and that I was able to get through a busy week of calls and conferences with no complaints about the clarity of audibility of my end of the conversation with the Blu sitting unobtrusively on my desk. Unless ANC is needed, Blu+Starfield >> Sony WH-1000XM4.

    The Blu's Bluetooth implementation is first rate. I listen to multiple sources: Android Phone, Linux notebook, and my work Windows notebook. Pairing, connecting, and switching BT is distinctly easier with the Blu than with other BT devices that I have used. The WH-1000XM4 is a finicky PITA in contrast to the Blu. Great job with that ifi.

    Most of my gear is at my Madison location, which I've been away from for a while, so I do not have much other than the Starfield that I can pair with the Blu at this time (my kingdom for a 6.3mm F to 3.5mm M adapter). I did grab my Neumann NDH 20s off the shelf for some quick listening. The Blu drove the NDH 20s just fine; quirky tuning preserved, with no feeling that they are underdriven.

    I'm pleased with the Blu's functionality and convenience. And it certainly sounds fine, though I've not yet had an opportunity to challenge it with demanding, highly resolving headphones. I would be great for a grab and go setup, as part of a road warriors arsenal, or in a bug out bag. It might also be good introductory or stepping stone gear for portable listening, particularly if it does rise to the challenge of driving higher tier headphones. Because it is so versatile, one can enjoy in in a primary chain and then shed no tears when upgrading to something else, knowing that it will continue to be useful in a secondary role. At $200 the ifi Go Blu may not be an everyone buy it now bargain, but it is a good value if one has a use for its capabilities.

    Thanks a lot for your feedback and also for highlighting our BT implementation. It took us a while to make it work nice and sound great, so your take on it relly made our day! ;)
