Clip On Over Ear Cans: Audio Technica ATH-EQ77.

These were given to me. The design is a good idea that unfortunately does not work at all well in practice. There is too much sound leakage in and out, the drivers do not fit next to the ear snug enough to provide any measure of seal. They cannot be used for serious listening due to this fault and therefore one can only hear the high frequencies mostly. Sorry but these only merit a 2 out of 5.

Manufacturer's Description:
ATH-EQ77 is Audio-Technica unique design Ear Fit clip-on headphones. Features a new "Wind-Up Mechanism" function that allows you to retract both and headphone cord and the neck cord. It is the first retract system on a clip-on headphone, so it is easy to carry and less tangle between the cords. Adopts neodymium magnet that gives high quality sound. Soft rubber support that gives you a total comfort around your ears. Available in 6 different colors, Black, Blue, Green, Red, Silver, and White.

    Earphones: Meizu PT850

    The Meizu PT850 earphones are completely uninteresting (plain Jane), plain to look at (in fact quite cheap to look at), they look like the usual give away ear buds of low quality that come with MP4 players that you don't expect to deliver any performance at all. Some places advertise them for US$10.00. I picked up my pair in fact for US$3.60 and probably the best $3.60 I have ever spent.The sound quality is unusually and surprisingly good for such cheap earphones, the bass rendition sounding like those of ear buds at many more times the cost, clarity and accuracy of mid and high ranges is sharp, crisp and crystal clear (not raspy but razor sharpness). Quite frankly I was quite surprised with the results from these earphones. I have both the Meizu PT650 and PT850.

    The PT850 has no frills, even the plug is not even gold plated, but who cares with astounding performance to price ratio, you can't lose. They come in white and black color, and I purchased a black pair. I have found that a very good synergy is made when match up yo the FiiO E3 headphone amplifier. Whereas the PT650 has a gold plated plug and a volume control on the cord.

    7 Range Sound Level Meter

    The photos below show one of the two different sound level meters that I own. The meter is used to measure sound intensity and for analysis of in room acoustical environment for optimal placement of components and and speaker and proves to be a very versatile instrument. If you are serious about obtaining the most from your hi-fi system the you should have one of these instruments in your armoury.

    This meter features include:

    • 7 sound level ranges - allowing measurements from 50 ~ 126dB (referenced to 0.0002ubar);
    • A and C Weightings - Let's you check using different ratings for acoustical analysis in different environments;
    • Slow and fast response settings - Choose from a delayed hang time meter response or a fast meter response;
    • RCA Output Jack - for connection to home system or other test equipment such as a spectrum analyser to check frequency responses at given locations;
    • Threaded Insert - allowing for stabilized mounting on top of a camera tripod for stability and accurate readings.

    Bionic Ear [CVETM-SBE001]

    Bionic Ear - 100 Meters Sound Distance

    My bionic ear CVETM-SBE001 set is a highly directional microphone with a directional parabolic dish to focus and amplify sound up to 100 meters. I use the bionic ear to listen to bird song and wildlife on walks. The amplified audio is delivered to a stereo headphone and can be outputted to a tape recorder. There is in built volume control as well as a digital audio recorder with playback function.

    • Sound Distance: 100 Meters Max
    • Built-in Monocular: magnification x8
    • Digital Sound Recorder: 12 seconds (new file records over last)
    • Headphone Jack: 3.5mm
    • Power Source: 1x 9V Battery
    • Dimension:
      Sound Gun: 175x280x55 (LxWxD)
      Sound Dish: 250mm round 60mm(D)
      Stereo Headphone: Adjustable Length 160mm~200mm
    • Manufacturer Ref.: VAWZ73LNX7EX


      Other Features:
    • Sound Band Adjustment: Expands/Narrows the cone of sounds picked up to find particular sounds
    • Sound Playback
    • Line in to transfer sound file to tape recorder

    Earphones: Sony MDR-EX700LP (top of the line).

    Yes these are the top of the line earphones from Sony. The impression one has when plugging and listening to the ear buds is that they are smooth as silk and the "Wow" factor on the musical impact although high is not one that is unforgettable. They sport no less then 16mm sized driver units. Although smooth, I did notice that there was not any gut wrenching bass and I noticed that Sony's new 'phones are far more concerned with the mid-range than the highs. Nonetheless the music was very delicate, refined and polished. Overall these are warm sounding earphones and would be suitable for vocals and folk music from my initial listening.However as with high end cans the burning in of the cans will likely make a dramatic impact on the optimization of the sound quality and this remains to be seen over the coming weeks ahead. After a listening session of 2 hours, I did not find any discomfort at all, isolation is good but they are not the best. There is room for the high frequency range to improve and I hope with further burning in that this will occur. Sony has supplied no less then 7 sizes of ear tips!


    Sony's High end Earphones at US$299.99

    Featuring 16mm driver units and a thin magnesium housing, these MDR-EX700LP ear bud headphones faithfully reproduce your favorite music with stellar results. The multi-layer diaphragm design makes even the most subtle sounds heard, while the seven included silicon ear buds ensure a proper fit.

    Armband Digital AM/FM Radio: GPX A2099RSYEL

    Was out walking in Kowloon and came across a GPX A2099RSYEL AM/FM digital stereo radio with neck band earphones for US$9.90 and so bought one. This is a nifty little LCD digital scanning tuner with lock an 5 programmable memories. It also has a DBBS switch to create extra bass. Comes with armband. Nice little radio for jogging and hiking. The sound from the supplied earphones are actually OK but of course not hi-fi quality.

    Sung by-Deborah Holland

    Your Life

    Day After Day
    Everything that you do
    You do the same old way
    I can show you the World
    In a different light
    Keep your Heart to yourself

    Come to me
    When you're Lonely

    Come to me
    When you're Restless
    'Cause I've got something just for you

    You can wait
    Your whole Life
    For the Sun to rise
    When it finally comes up
    It's gonna hurt your eyes
    I can show you the World
    In a different light
    Keep your Heart to yourself
    Give your Soul to the Night

    Come to me
    When you're Lonely

    Custom Made Stereo 3.5mm to Stereo 3.5mm Using Oyaide PA-02 PCOCC Cable.

    I have just made a length of interconnect with two high spec Canare 3.5 mm stereo jacks on each end and a 1 foot length of Oyaide Electric PA-02 PCOCC Cable. This is used as interconnect between headphone amplifiers and source equipment such as CD player or MP-4 player.


    Oyaide PA-02 Cable Details:

    PCOCC-A

    PCOCC copper is a material that includes very few impurities and insures very low levels of signal disturbance. Because of its low incidence of grain boundaries, the signal passes without impediment or distortion. Heating and cooling the PCOCC wire under controlled circumstances yields a densely re-crystallized, highly pure structure called a μ conductor. The resulting product with a mirror finish applied is called PCOCC-A copper. This highly advanced product is made possible by the combined application of high technology and traditional Japanese craftsmanship.

    Structure/Insulator

    For PA-02, we employed traditional balanced type shield wire structure and triple-layered inverted concentric structure which insures maximum density and uniformity of wire structure and infilling of internal space and preventing deformation among the wires.

    For its insulation material, we employed formed polypropylene which is a low-dielectric material and insures reduction of loss of signal transmission.

    Outer sheath

    In addition to PCOCC-A conductor, the halogen-free sheath developed specifically for audio applications is applied for PA-02 with assistance of Furukawa Electric. This RoHS compliant sheath has excellent vibration damping property and high transmitting capability by ideal compounding ratio of materials.

    Earphones: Splendor SP-107MV Soft Aircushion Earphones (from Korea)

    A friend sent to me an intriguing set of earphones from Korea called the Splendor SP-107MV Soft Air cushion Earphones. A run on yahoo and Google did not find anything about them? They are open air dynamic type air buds and the novelty about them is the inner tube like silicone ring which runs the circumference of each driver (what they deem to be their soft air-cushion). The packaging seems up to date styling with little English and mainly in the Korean language.

    They have a volume control on the cord and the cord is grey silicone rubber of 125cm length with a gold plated 3.5mm stereo jack. Plugging them in and listening to them did not yield any interesting findings. I found the design uncomfortable and the placing of each ear bud in each ear had to be very carefully aligned in order to obtain the proper and wanted frequency response from them. The sound is light and undramatic, I would venture to say bland and uninteresting.

    At first hearing they do not appear to show promise, just only a little bit better then the general run of the mill ear buds that often come with MP4 players. Generally the music was uninteresting and unenlightening. Bass extension did not seem to be there. All in all they did not create an interest for the listener to listen to the music. I will however let then burn in for 15 to 20 hours to see if there is any further improvement. But the general discomfort and the difficulty in proper alignment means that it is difficult to replicate consistent tonal performance each time. Given the above scenario it is difficult to even give them a solid 3 out of 5, I would say 2.8 is a max that I would give.

    They are a novelty since they are a gift from Korea, the only thing is that they are not made in Korea but in China. Well one more pair to my ever growing collection. Pressing them against the ear canals was altogether a different story with the whole frequency range opening open, the bass extension was there, the punch to the music became more evident. It is obvious that the drivers are of good reproduction quality, it is just the ear bud design that let's the performance down. If these drivers were in a better casing I think it would be a different story! Anyway, I will let them burn for some hours.

    Their Specs:

    Type: Open Air Dynamic Type (Air Cushion)
    Frequency: 18~25,000Hz
    Sensitivity: 110dB/mW
    Max power: 500mW
    Imp.: 32 ohms
    Plug: Gold plated 3.5mm stereo Plug
    Cord: 125cm with volume control

    Running further searches I found:

    US Patent 6731772 - Cushion cover for preventing pains in using earphones

    US Patent Issued on May 4, 2004

    Abstract

    The prevent invention is related to a cushion cover to improve adherence and to prevent pains when wearing earphones which deliver sounds of various portable small-sized recorders, radios, etc. by inserting them into earholes inside of earflaps for a long time. The cushion cover which covers the circumference of the insertion portion of earphones in the present invention is composed of the fixing-in portion which is grounded to the above insertion portion, the ear connection portion which is grounded to the inner earflaps, and the air chamber which absorbs the pressure added to the fixing-in portion and connection portion in order to soften adherence to earholes.
