Otherwise, it makes one question why a respected designer and manufacturer of mid- and high-end audio would release a product with such an obvious flaw.

+1

Perhaps Chord can fork another model without the bluetooth feature and save costs to us.
I personally avoid wireless where it matters most, audio, data xfer speeds, gaming.
Wouldn't bluetooth bottleneck the high quality of this product anyway?

I heard static when using BT when the only wire connection to the Hugo was good quality RSA cables out to a headphone amp, and when I switch input to USB the static went away.

Several people who have aptx codex have reported problems, so something seems to be up.  For many of us, the quality of bluetooth doesn't really matter, because the most common version of aptX codex is going to hold the Hugo back... it only goes up to 384 kbit/s, not good enough for me when doing serious listening.  In other words, the quality (or even presence of BlueTooth) has virtually no impact on my buying decision.  It's a "That could be cool.  Every now and again it might be useful."

Seems like there is near universal negative experience when paired with lower grade BT codex  (most iDevices users).  When I demoed the Hugo I had audible static when using BlueTooth.  I didn't comment on it at the time because it is very unlikely that I would ever use BlueTooth. I would use the Hugo via USB or optically connected.  I have come to expect sound quality limitations from BT, but my iDevices do pair with a number of other BT devices without the same level of static (though I have the same static problem with my Jawbone Jambox).

Hi Mark

Please don't misunderstand , I don't like the blue tooth connection too biggrin.gif
Like what already mentioned in previous page back , the best SQ from Hugo are :
Coax > USB high res > optical cable >> blue tooth

I just connected the Hugo to my iPhone via Bluetooth. Other than trying to figure out the four digit code there were no issues. Via onkyo hi fi player I streamed all types of music from flac to dsd. The light stayed red on Hugo so that shows lowest Rez. No noise or issues. Sounds fine to me. No buzz or hiss or background noise. So here is one Hugo unit that sounds just fine. Not as good as via HD USB or coax but for BT pretty darn good. No issues.

Pls quote what earphones/headphones and their impedance when you report if noisy or quiet bluetooth inputs.

 

Let me start:

UE18 pro 21ohms extremely noisy even if paused no music

Sony EX1000 32ohms less noisy but same effects as above

 

I suspect lower impedance earphones will notice this more easily

[edited with correct impedance for UE18 pro]

Some experienced member mentioned that the bluetooth shares the same frequency range as wifi and it will likely prone to interferences when use in a busy wifi area eg. office

Yes BT shares the same frequency as 2.4Ghz wifi but this happens even when no wifi signals nearby and I don't have the same issues on my other BT headsets.  Chord did mention they only use BT as a transport without a dedicated BT chip to decode the signal and routes it to their DAC so perhaps the Hugo is picking up extraneous noise then amplifies it.  I only use 5Ghz wifi so shouldn't have inteference from BT.  Plus the fact it's still noisy when I disable all wifi at home.

On another note, what headphones pair well with the Hugo, I'm using UE18 pros and have ordered the JH Roxannes but want to max my enjoyment from the Hugo so will consider full size cans.  My only consideration is isolation as I hate hearing outside noises.  I enjoy clarity and layering.  Feel free to mention any particularly worthy cans, thanks.

I put my own 3a/16pro on to a big battery and found myself at a whole different level sound quality wise. THE HUGO RUNNING ON IT'S OWN BATTERIES IS LIKE YOU RUNNING E85 IN YOUR CAR!

This is from the master class ppt. It seems chord has seriously considered the power problems.

I read the aumacoustic. The problem of batteries is addressed but not solved anyway. A USB to spdif converter and a power supply are introduced but the internal battery is still there... It's no way a modification to bypass batteries.

So, what are you saying?  There is no way to modify or bypass the Hugo batteries?  What about replacing the batteries.

I mean this "problem" comes from nothing but the solution adds some cost. I could be wrong.

Here is the confusing part, designers normally use battery as it is much cleaner than most PSU system out there, I think we are pondering on a non-existing problem.

It looks like there is an offer on Hugos at Unilet Sale that starts tomorrow at 9am GMT, you also get a free vertere cable.

The chord guys could only work within the available BT audio protocols that are current in phones today. ie it's a limited audio performance transmission medium that was designed into the Hugo as a last resort close range pairing choice from your phone in your hand to your Hugo in your pocket. It seems from your detailed descriptions that many of the issues lie within the realms of the transmitting devices and or software and The wish that a2dp could be as good as a solid link. Unfortunately at this time it can't! But next year who knows !
