Hey guys, so I picked up a pair of used Sennheiser HD 451 on the cheap, I pulled off the ear pads to give them a wash and noticed that the driver is covered by a circular "hubcap" that covers more than 50% of the driver. The question I have is, does this cause interference and can these...

So I've been go ogling around I thought I had discovered them to be the HD 200 Pro, after looking at the 451 they appear to be the same headphone :-/ are the 200 and 451 the same thing branded for different markets?

Hey guys, I have the chance to pick up these sennheisers for $5, it's so cheap so why not. But Ive never seen this model before and can't seem to find them online. Anyone know what they are?

I would agree with this. I bought the ZS5 when they were on presale, from one of the big Aliexpress sellers. I paid something like 32 euro, including silver cable. This was a good enough deal that I jumped into the pre-sale. But the price almost immediately dropped down to 20 and now 17 very...

I FINALLY received my ZS5 after waiting over 40 days, having ordered during the pre-order phase. I will post a more thorough review after a bit more use, but my initial impressions are very positive, they do sounds pretty damn good, and I was lucky enough to get the "premium" box with magnetic...

The 17track link has the same status, I'm ordering to Germany. So for you it's also gotten "stuck" at this status but was in fact already dispatched by air mail?

It feels like I've been waiting forever for delivery. I ordered over a month ago and this was the last status on tracking. Can anyone with more experience using Aliexpress shed some light on what's happening here? Looks like it's stuck at Chinese customs for 3 weeks:

What do you mean by this, that she's banned? By the way, I had been waiting since 23.05 for my ZS5 to ship, and they finally did yesterday! Hoping the shipment is fast.

I placed my order for ZS5 9 days ago, and it has still not shipped :/ Anyone else still waiting in the pre-order backlog? I ordered from Aliexpress seller ****.

I got a response from the seller **** about which cables you get if you order a silver or gold. They confirmed you will always get the original cable (whether you choose with mic or without) plus the extra silver or gold cable. I placed my order. Now the waiting begins... :upside_down:

In response to cable questions, does anyone know how these Aliexpress merchants sell the KZs when you select the silver cable when you buy the IEM. Do you get the silver cable as well as the original black, or only the silver? Because buying the default black and then a separate silver is the...

So what is the comfort going to be like on these ZS5? Looking at those angular edges makes me... uncomfortable. Any comfort impressions? Also, would anyone recommend the silver cable over the regular ones? I'm skeptical it will affect audio quality, but what about microphonics, comfort...

Thanks for your response. Have you compared the ZST with the Tennmak Pro? Which would you recommend? I'm looking for a balanced sound with good treble clarity. Thanks!

Hifiman re400s are going for about $50 on Aliexpress right now. How do they hold up the onslaught of recent chi-fi? And has anyone done any direct comparisons between the KZ ZST, and the Tennmak Pro? If they were equally priced, what would you choose? Might as well throw the re400s into the...

Hi all. How would the ZST compare to an earphone like the hifiman re 400? Has anyone done a comparison?

Thanks for that link! I obviously read the whole page, bringing back memories of late nights poring over detailed reviews of the fine nuances between headphones    But honestly it's so confusing launching into these comparrisons, and time consuming. The cable issue with the RE400 is a put-off...

No opinions about the RE-400, and IEMs around this price point?

The last time I was active I considered getting the RE-400, somehow that didn't happen because I was quite happy with my modified ZMF Fostex T50RP and AudioGD dac/amp unit.   Anyways, I got the HiFiMan email with the black Friday specials and the RE-400 is down to $79 dollar.   Suddenly I've...

Hey Taveren, unfortunately I don't. You know, I'm sure the 15 and 11 sound very similar, but if the T50RP is going to be your primary phone I would go with a 'brighter' amp, because the T50s are already very warm and lush in the mids. I think there's a chance they would sound too dark. As I...

Finally received my ZMF v1 a couple days back and have given them a lot of head time over the weekend with my NFB 11.32.   Initial impressions are very positive. I'm quite pleased with their bass response in particular, they really sound great for electronic music and synthesized...

Hi omid. It seems that you're quite set on going with Sennheiser, nothing wrong with that, but I'm sure you will get other suggestions within your budget. In have owned HD555 for many years, they are exactly the same headphone as 558 and a little cheaper. Surprisingly 555s don't get a lot of...

@stv014 Thank you for the very useful information.   @agdr Wow. You've done an incredible amount of work on that, it's very impressive. Definitely adds some good features to the minimal O2 design. I've always felt the O2 is somehow just 'not quite right'. It seems conflicted whether to...

Quote:   There seems to be growing consensus that orthos benefit from higher current, so I thought it could be an interesting modification for these kind of phones. There's been lots of talk of people strapping their cans to speaker tabs and the like. What would happen if you added even...

Quote:   How much does that component cost? And why isn't that standard practice? Have you heard this configuration?   Thanks for your response.

Hey guys.   DIY related question. How difficult, if at all possible, would it be to increase the current of the amplifier circuitry, ie. to increase the wattage. Is this feasible?   All of O2's competitors have greater output power in terms of watts per channel. I'd be interested in a...
