Hong Kong's Electronics Golden Mile - Ap Liu Street (Aka Hong Kong's Akihabara)

Ap Liu Street in Kowloon, aka Apliu Street and also known as the Hong Kong Akihabara, is like a market place for electronics shopping and side stall flea market all at one location. It is located in Shamshuipo and you need to take the mass transit railway and get off at Shamshuipo station There are probably hundreds of stores on that street and the side streets connected to it. Then in the middle of the streets, there are stalls selling both new and pre-owned gear and junk (working and not working) as we as knock off electronics, hi-fi, headphones as well as legit. imported and Chinese made products . Here is a short list of the kind of products found in the Apliu Street:
  • audio equipment e.g. mixers, microphones;
  • amateur radio equipment (namely CQShop and Tung Shing);
  • automobile paraphernalia (specialty shops);
  • Backpacks (new);
  • camera lenses (used);
  • cameras (used);
  • cell phones (new / used);
  • clothing (new / used);
  • consumer electronics (new / used);
  • electrical appliances (used);
  • electronic parts (new);
  • fishing rods (new);
  • florescent light tube, different colors, shapes, and sizes (new);
  • hand tools (new / used);
  • handheld radios (FRS/ham/commercial/marine);
  • headphones and earphones (Real McCoys/Knock Offs/Chinese Brands);
  • hi-fi (new/used);
  • phones, wired or wireless (mobile/DECT/2.4GHz/5.6GHz -new / used);
  • photographic accessories (new);
  • pots and pans (used);
  • power tools (used);
  • radio-controlled toys (new);
  • remote controls for TV, hi-fi, air-conditioners (new/used);
  • satellite dishes and reception equipment (new);
  • security monitoring equipment (new);
  • telescopes and binoculars (new);
  • TV sets (used);

  • watches (new/used);
Whilst Akihabara in Tokyo has been shrinking in size in past years, Apliu Street in Hong Kong has been growing. It is a crowded place so keep your hand on your wallet and look after your valuables.

If you are making a purchase at on of the stalls along the street be prepared to do some haggling and you will get a price reduction.

A Word On Fake Headphones And Earphones.


So far I have not written anything on fake headphones in my blog. I have seen my fair share of fakes come out of China with branding such as Bose, Senn, V-moda, AKG, Audio Technica, Sony and Pioneer.

Inevitably if you are familar with the original product you would be able to spot the differences between the real and the fakes. As for sound quality, whilst sound quality on some of these fakes I have listened to are quite good in my opinion, they are still not the same as originals as the drivers and the materials are just not at all like the originals and performance will not be on a par.

Another way to spot a pair of fakes is the huge difference in price between the fake and the originals, you cannot expect that you are getting a genuine pair of headphones if you are paying on a fraction of the real price. Many of these fakes are being touted widely on ebay as the real Mcoy. So buyer beware, don't start making a big nosie and fuss if you paid under $50.00 for a pair of headsets that would cost well over $150.00. Let's face it, there just is no free lunch and you should not be so vain.

Even though we see so many knock offs emerging, I will take my hat off to those manaufacturers who are producing quality headphones and earbuds which are not knock offs and either have their own brand or in some cases no branding at very low prices. I have found some unknown headphones and earbuds selling for peanuts but the performance being in the upper price categories. Hi fives and kudos to those manufacturers who produce the high quality non-knock-offs at very economical prices.

But if you go and buy something cheap with a major brand name, I would not start to complain about your item being fake as you should really have known better. Just don't buy them if they seem unreasonably low priced. Just my 2 cents.

Wooden Cans: Unknown Chinese Wooden Earphones.


Saturday morning strolls though the hi-fi shops in nearby Shenzhen, one will be particularly lost if you are in one of the speciality shops that sell headphones, earbuds, portable amps. etc. It's just like being a kid in a candy store. There are just so many headphones and earbuds that your mind just cannot come to terms with. Inevitably these stores will separate the legit, the look alikes with known branding and less then legit and lastly the no branding or Chinese branding headphones and earbuds.

Well many Saturdays ago, I was in just one of these shops looking around the Chinese made earbuds and was looking at a pair that had the outer shell made of wood (the sign said that it was Teak?). Then this shop assistant comes up to me and begins to tout them saying "Very good, Chinese JBL Pro Standard", of course I thought this was typical hype.

He continued - "Try, try, you like", so I guessed what the heck and asked him to plug them in. I listened to them through a Little Dot Mk 1 which was connected to a Sony CD player and placed a Scott Hamilton saxophone CD which I had in my bag and pressed play. Immediately I was so drawn into the pace of the music produced by these wooden cans, it was unbelievable, the highs were so crisp and clear, so much detail could be heard. The sound stage was so well defined and not too large or small and seemed just right. My only feeling was the bass extension was slightly less then norm but quite frankly more then adequate.

The shop assistant then proceeded to produce a real pair of JBL earbuds and also a pair of Shure earbuds and let me compare the three pairs. I just could not believe it, the wooden buds beat them all and it was basically no contest. So I asked him, how much for these wooden so called Chinese JBL Pro earbuds. He told me the price and it blew me away, take a guess? No idea, they were $5.00. Who could argue, so I took away two pairs. These are some of the best stock earbuds in my collection which consistently blow the $150 plus cans out of the water. In fact they look a little like the JVC HP-FX500, except the JVC use a different type of wood which is much darker and retail for about US$130.00. All I can say is amazing, and worthwhile spending the $10.00.

We shall be seeing more and more high quality Chinese earphones and headphones emerging in the near future. I don't really care if there is any branding or not, it's the quality the leaves you bewildered. Not much on specs, very brief:


Specs wise:

104 dB/1mW
from 8Hz to 28kHz
drivers are 9mm

Earphones: Sony MDR-EX90.

The SONY MDR-EX90 earphones are noise-isolating earphones with awesome, stereo sound. Street price is US$89.00 per pair. The major critical difference between this earphone and the others in the Sony MDR-EX series is the size of the drivers. This earphone uses 13.5 mm drivers, whilst the MDR-EX81, MDR-EX71 and MDR-EX51 all use 9 mm drivers.

Larger sized drivers yields distinct improvements in sound clarity, and greater efficiency.with lower drive levels. These earphones are rated at 106 dB/mW whereas all the ones with the 9 mm drivers are rated only at 100 dB/mW ( a 6 dB improvement!). With about 3dB we would all hear a clear difference in the volume level.Testing out the earphones the human voice came out more naturally and I could hear deeper bass and clearer highs with more overtones and longer resonances. The mid range is sweet and listening to saxophone was particularly enjoyable. The highs are crisp and not shrill and the lows are deep and rich. The in canal ear buds are very comfortable and do not hurt after protracted periods unlike some others.


The use of 13.5mm drivers gives IMHO gives far better dynamic range and significantly better bass extension besides delivering more natural sounds.

They are in my opinion, a better buy than the Etymotic ER6 which I have listened to.The rubber is softer and much more comfortable than the Etymotics which always end up irritating my ear canal to no end. The MDR-EX90's produced warmer, more pleasant sounds then my Shure or Eytomotic earbuds when compared.

Specifications:

Type: Closed, dynamic
Driver Units: 13.5 mm (CCAW adopted), dome type
Power Handling Capacity: 200mW (IEC)
Impedance: 16 ohms at 1kHz
Sensitivity: 106dB/mW
Frequency Response: 5 - 25000 Hz
Cord: 1.2m, Oxygen Free Copper litz cord
Plug: Gold-plated, L-shaped stereo mini plug
Weight: 7 g (without cord)

Technical Details

  • Stylish and convenient stereo headphones
  • Neodymium magnets deliver excellent sound; 13.5 mm driver offers wider dynamic range
  • Metal housings cut vibration
  • Three sizes of earbuds included to fit your ears
  • Hard leather case holds your headphones; 1.2 meter cord for ease of use

Full Size Cans: Sony MDR-V900 Studio Monitor.

The Sony MDR V900 Studio Monitor Headphones are no longer in production, but some of these headphones are still available if you do a search on the web. Originally priced around $150, they are now going for under US$100 and are considered a good buy. There are variants to the V900, so make sure that you are getting the Studio Monitor. There is one version which is even more up market known as the MDR-V900HD which is even still available via Sony at over US$250.00.


The frequency response for the Studio Monitors are quite wide - 5 Hz ~ 30KHz, some people have commented that there is a slight booming of bass around 70-80Hz. In reality the Studio Monitors are quite flat and allot is depends on the "quality" of the source equipment. The headphones are very comfortable and the sound reproduction from them is excellent. Bass and treble extensions are dealt with quite well and the headphones score a 4.3 out of 5.

Studio Monitor Series Headphones

incorporates state-of-the art engineering design to produce excellent sound quality and wearing comfort to accommodate high end consumer or professional applications.

Circum-Aural Earcup Design

in the natural shape of the human ear positions the driver unit at a correct distance from the ear canal and creates a sealed resonance chamber over the earlobe itself, reducing pressure on the ear for a more comfortable fit, especially during extended listening sessions

50mm Aura-Nomic Designed Driver Unit

is positioned within the earcup at an angle which directly corresponds to the angle of the opening of the ear canal for the most natural listening experience possible

Neodymium Magnet

is small, yet five times more powerful than a ferrite magnet of comparable size, to provide a better headphone without increasing the overall size and weight of the driver unit; The stronger the magnet used to provide the return energy of the voice coil and diaphragm, the more accurate the driver unit will be in reproducing the entire sound spectrum

Oxygen-Free Copper Voice Coil

construction provides exceptionally high power handling capability of up to 3,000mW

Amorphous Diamond Evaporated Diaphragm

stiffen the drivers to maximize their tonal qualities while minimizing additional weight for much more natural sound

Fun Cans: Audio Technica ATH-ON3 Portable Headphones.

The Audio Technica Onto ATH-ON3 Portable cans were originally purchased for the purpose of using them for use on my transceiver for late night chats because they were small, uncomplicated and easy to use. But testing them I found that they were quite a like able set of headphones for portable use also on my daily commutes and easy to store. sound is also quite decent and bass response is quite good going down to 12Hz. The sound stage is actually quite wide with these cans. The price is quite low also at around US$19.00 and they come in a large selection of colours. I found the lime green with brown ear pads to be quite attractive so opted for this color.

    News On New FiiO E5 Headphone Amplifier.

    News direct from FiiO factory on the E5 sent to me by PM today. Recharge batteries included, metal case for better RFI Shielding (No photos at present time though) and under $20:

    Dear Steven:
    Thanks for your interesting in our E5, the detail information now are available in head-fi, you may read the thread! and about the retail price, I can tell you what would happen in china mainland market, it will be about 16USD , but about the oversea market or ebay, consider of the shipping cost, I can't tell you the price!

    So, you can see ,the price is very reasonable for a metal case , with a MCU controller inside, rechargerable-battery, and upgrade sound quality!

    Also, we are thinking about maybe we can develop a desktop DAC with headphone output, digital amp , so those people like music can uses laptop PC/mini PC as a digital music source! of course, We will keep the price in a reasonable price level!


    Thanks and best regards!


    2008-09-18

    James Zhong (FiiO)

    They are also thinking about a DAC unit version, would that be the E7?

    Modifying The Koss PortaPro Headphones.


    I am not going to make an introduction to the Koss PortaPro Headphones as most Head-Fi buffs worth their salt would already know about these portable headphones already and most likely own a pair in their arsenal of of headphones. But quite briefly they have been around since Adam was a boy and the retro styling has remained the same and is almost timeless. They are famous for being able to deliver punchy bass for a set of very light weight headphones, others have tried and died! You can check out the Cnet video I posted earlier in the month on an introduction to the PortaPro heaphones.

    What I have always hated with these sets is the el-cheapo foam pads which they use for ear pads, they are uncomfortable and do not last very long. So today after work I decided I would go and buy some leatherette type ear pads and fit them to the PortaPro replacing the el-cheapos! So here are the pics of the conversion, before and after:

    Photo 1 above: The new leatherette pads before insertion.

    Photo 2 above: The Koss PortaPro's with the el-cheapo foam pads before removal.

    Photo 3 above: The Koss PortaPro's with the new ear pads in place.

    With the conversion my ears don't hurt as much using the PortaPro headphones and the end result also provides better external sound isolation making the whole listening experience much better then using the el-cheapo foam pads. There is less sound leakage and therefore I am hearing also more detail at lower volume levels then before.

    Fun Cans: Cans In A Can


    The following earbuds have no maker's name or model to go by and they were given to me as a gift.

    There are even no specifications except that the frequency response is from 20Hz to 20,000Hz and that is it. I was told that they retail across the border from here (10 mins. on the MTR east route rail to Shenzhen) for only US$6.28.

    As for sound quality, they are slightly better then a pair of stock ipod buds but I would say are in the vanilla category.

    The packaging is another story and is as cute as can be, I really don't think I will be using them for any serious listening but they are quite a nice fun pair of cans in a can for packaging. So I have named them "Cans in a can" for obvious reasons. A nice novelty and conversation piece over coffee with some head-fi friends.

    Full Size Cans: Pioneer HDJ-1000




    Well what can I say about the Pioneer HDJ-1000 full sized cans, they have unbeatable sound, great comfort maybe not, lightweight no/foldable for storage/travel yes. The phones were designed for professional DJ use. The price range is around US$150 to US$170 for a pair so you need to really shop around and get the best price.


    Apart from the great ambiance, sound stage, air and timbre recreated by these cans, the full impact of the music can be rendered like recreating a masterpiece painting in your ears and not before your eyes. The down size is that I consider them bulky and uncomfortable for protracted periods of listening. They do win hands down on the sound isolation department and cut out outside noise. I do use these for mixing and burning of CD tracks. These belong in the winners arena.

    Out of a 5 I will give these cans 4.7 rating, deductions for not being comfortable for long durations. The bass impact is incredible on these headphones sinking in deep into the lower registers and holding tight all the way without feeling muddy. A real sonic experience, the mid range is so utterly sweet and refined.

    General Specifications:

    • Manufacturer :Pioneer

    Entry Level Headphones: JVC HA - RX 300

    I have been asked by some friends about what would be a good pair of entry level full sized headphones to consider. So today I wish to talk about my JVC (Japan Victor Company) HA - RX 300 full sized dynamic earphones. I have not seen much talk about these headphones, but they are worth a mention as they are light weight, well designed and exhibit a very good bass and mid range response, upper ranges does not stand out and glare. These headphones are easy on the ears and are great for general easy listening.

    These are definitely a pair of cans for those starting at entry level at around US$18.00 on the web, the design and looks are good and the sound is definitely a 4.3 rating out of 5 for a pair of low priced range cans. A difficult act to beat.

    So what are the disadvantages, there is slight coloration in the middle and lower registers (I would expect this as normal for cans in this price range), but hey remember we are talking about a pair of great looking entry level cans for the starter at under US$20.00 who wants something sleek, good looking easy to use and great for general music listening.
