Q701 impressions thread - Page 601

post #9001 of 9012

So I bought a new Q701, proudly made in China.

 

Everything's great, except when I start playing music, there's always a high-pitched pop right before the music kicks in. It's not before every song, but only first time the headphones are played. And no pop until I disconnect the phones or no audio is played for a while. This happens on every device, my M-Stage, PC, and phone. The pop is loudest on my phone, then the M-Stage, then quietest on my PC.

 

I know this is a dud, since I've owned like 4 pairs of K70X in the past and none of them have had this issue. Rather, my real question is whether I should put up with this annoyance, and whether something like this indicates a problem with the wiring or drivers that may lead to further problems down the road.

 

Thanks in advance.

The pop happens when you press play, or when you plug/unplug?

On my phone, both when I plug it in and also when I start music.

On my amp and PC, only when I play music.

If it was me, I'd return the headphone immediately for a replacement. I don't care if it's a minor fault. If I pay for a new pair of headphones, I expect it to be properly new and working like one. 

 

Mine is made in Austria. Works perfectly after 4 years. In fact, plastic strip connecting the headbands are starting to crack but everything else is like new.

Return them. I have both Austrian and Chinese models and neither does this. I would say this is clearly a defect, and it will only grow more annoying over time.

Anyone here have any experience with Project Ember? I was going to use the Q701 when I buy it with a Lyr 2, but people keep telling me to consider this amp as it is a bargain. I'm still not totally convinced about it though and would still rather get a Lyr 2.

I recently exchanged my Denon DA-300USB for a Matrix M-Stage HPA2 USB (driving my Q701, as amp & DAC). It is a world of difference. A few pages back someone said the Q701 sounds harsh without a decent amp. I'd say that is definitely true. When 'low' powered with the Denon my Q701 gave a lot of highs, slightly recessed mids and really recessed (almost none!) bass. I wish I had been better informed when I bought the Denon...but well.

 

The M-Stage totally fixes the above for me. High, mids and bass are way more balanced now. Especially the harsh part of too much high changed dramatically, as both mids and bass are way more in line/balanced now. To me it was quite an eye-opener - it DOES matter how you amp your Q701. I enjoy my Q701 way better now than I did before.

I don't know. When at my desk I plug my Q701 right into the speaker outputs of an Emotiva Mini-X A-100, but I also use them plugged right into my HTC one M9. The M9 has a very powerful (at least for a phone) amp inside, but it is still nothing close to the power output of the Emotiva, but I still enjoy the Q701 straight out of the M9. It's at least 90% as good. I know I've said it before, but I think people blow the need for extreme amplification out of proportion. When plugged into the M9 I still don't exceed the 80% mark on the volume. It's got plenty of power to get them plenty loud and they still sound like a Q701.

This is exactly my experience with my Note 4 vs, NFB-28. Synergy is something I haven't played with as much, as my amp is basically wire with gain, but I think power really shouldn't do much.

You've just illustrated precisely why I always recommend a used M-Stage with Q701 over the supposed straight wire with gain so often promoted on the forums, which is anything but that. Some folks think that amplifiers only make the sound louder. That's true to a large extent. The question is, how well? Of course one can get fairly loud-seeming levels with the Qs and a phone. Mostly in the presence region. BFD. Full-range? Ruts-a-ruck.

Is your Q701 bass modded?   Either way, does your point depend on whether the Q701 is bass modded?
