How do the PM-3's compare to Mr Speakers Mad Dog's? Their price points are close.

Hello Baradona, sorry, no experience with the P7 so I can not compare.

Hello GregH, I think these are a step up from the Mad Dogs 3.2. The sound signature is very different with the MD3.2 being subdued and very warm sounding but if fidelity is what you seek then these are a level up in my opinion. The MD3.2s are more of a kicked back sound and forgiving from what I remember, although with its sound sig I don't think it's suited for all genres like the PM3s are. The PM3s are a lively version of the MD3.2s, I wanted to write that in the review but chose to keep comparisons to a minimum. However I find the detail retrieval on the PM3s better as well as the lifted bass. I remember the MDs having a really flat bass, which to me felt really sterile and had not emotion.

Just weighed them with smaller audio-only non-mic cable on = 340 grams  total.
 13.0 grams for the cable itself. Unit's weight  is 327 grams then.
 
Fun trivia

This is odd, sure weighs heavy when holding or wearing it. I would think the he560 is lighter but the numbers shows otherwise! I wonder if the weight placement has more to do with it than distribution, or both!

Soundsgoodtome,
It's all about the fidelity. The best phones I have are a pair of Etymotic ER-4s which are very flat. Some friends felt there wasn't enough bass but I find them nearly perfect, especially tucked under a helmet while riding a motorcycle playing Mannheim Steamroller's Fresh Aire I or Billy Idol's Mony Mony (surprisingly good while hitting the twisties!).
I do read some negatives about the soundstage, including in your review. Would you say it's more related to the fact they're closed-back rather than a particular problem with Oppo's design?
.

Hey, a fellow rider! In that case then it's a matter of your personal taste. I had the Ety HF5 which are suppose to be the cheaper version of one of their higher ends (maybe the ER4P?) and to be honest I found the sound quite boring enough to send it back, so maybe we have different tastes? The soundstage isn't as bad as some make em out to be but to be honest I think it's just hard to find faults? They are closed back after all and doesn't sound anywhere near closed in as say the Beyer DT1350. I believe the Mad Dogs are on the same boat with the soundstage being closed, although I don't really recall that aspect of the MD's sound as much as the frequency response.

I honestly think that I could've foregone the mention of the soundstage, it's really not that problematic but it isn't open back. Compared to the HD650 which isn't really great in the soundstage department for an open-back (at least through an solid state), the PM3s aren't that much more closed in.

The ER-4s are exciting to me, although as my vocabulary is growing (I'm spending too much time on this board) I would say they run a bit to the bright side. I ride a Suzuki GSF 1250 "Bandit", btw. It's a standard with a ton of low end torque. I like pulling in the twisties and the Bandit really gets it there. It was also much less expensive than a comparable BMW!
 
Okay, so now my budget is $300-400...now I understand the board's motto, "Sorry about your wallet."  Sheesh, I just got here!  :-D

Very nice, I have a CB919 and quite familiar with naked bikes. Yes, very much sorry for the wallet. When I first got in the hobby I had an e17 and dt880 and was content. That is until I heard otherwise and then it was all downhill from there. Or is it uphill? Still trying to figure that one.

Don't forget to enjoy the music!

yea, headphones with suspension designs actually feel lighter even though their weight is heavier due to the way the weight gets distributed. Hifiman quotes the HE-560's official weight at 375g, but I do agree that when I wear the HE-560, they 'feel' lighter on my head than the PM-3 due to their suspension strap design.

A very informative review, I like how you described the sound signature, especially the bass and sub bass. Reviews such as yours, makes me want to immediately purchase the PM-3.

Thanks! I suggest either auditioning a set or trying them at a local shop but I can also say you can buy these without hearing them and chances are you're going to be pleased by your purchase.

Good review. Perhaps you could amend the review text to state that they wear, feel heavier on the head, than some phones that actually weigh more?
 
Also as a fellow naked rider, that means a naked bike, not a naked rider, Z750S, I have to say that I would never even think of wearing and listening to IEM's while riding. Extremely unsafe. Not recommended, and I've been riding for more than thirty years.

GS,
Not to get in an argument about riding but I'll disagree with you here. I believe riding without ear protection to be very dangerous, especially after decades of riding. Even inside a helmet there can be significant wind damage to your ear drums. Thus, rather than wearing ear plugs I ride with a good pair of IEMs and maintain a safe volume. I can still hear traffic, etc.

C'mon, no arguing of riding fundamentals here. Some people can listen passively, some get too distracted but always follow your local laws about having something blocking surrounding sounds and piping music into your ears. IMO hearing protection is absolutely crucial, just like a helmet is! I've been riding for 10 years on/off and about ~40k miles.

Amen to helmets and safe riding. I've been on bikes for 40 years and always gear up before the ride.
Speaking of gearing up: since you now have the PM-3s when are you getting that "nice DAP or portable DAC/AMP"?

I don't own the pm3 but was able to listen to it for a week via the PM3 tour by Oppo. Which btw is still open for registration, you just have to meet the criteria.

SGTM,
What is/are your main, go-to headphones?

Hifiman HE560 are my reference.

I should have gone with this headphones and saved $300 instead of going with the el-8 for planar magnetic headphones.

As with the PM-1 and PM-2, I would not characterize the treble response on the Oppos as "rolled off", but rather not unduly emphasised.  The treble is extended and detailed.
