    I've been using the Kenwood HS-5 headphones for 10 years or so. They are alright but would like to try some others. They sound pretty good. I use headphones ~85% of the time. If signals are strong I don't need them really but they are great when there isn't much there to hear.

    I think there are a few "great things" about using headphones:

    -They absolutely allow you to hear stuff you cannot hear with a speaker
    -They block outside noise
    -They block your own station noise from annoying the rest of the household!

    That last one can be very important for anyone who doesn't live alone.

    The HS-5s aren't bad. If you want to replace them, try Koss PRO-4AAs, which are available almost everywhere including all "pro audio" stores that sell musical instruments and such.

    Arlan Communications RadioSport RS20S headphones.

    These have 24 dB of isolation and are stereo (for transceivers with Dual Watch.)

    They have models with boom mikes, too.

    It might at first seem counter-intuitive, but Al with his military HS-16 phones has the highest chance of success on CW. The industry standard

    for commercial, shipboard, and military CW communications were heavy, "C-clamp" phones made by Western Electric, Utah, and Trimm. Standard

    set after WW II to modern times was Trimm Commercial, Trimm Featherweight, and the heavy Trimm Professional and Trimm Dependable.

    Look at any photos of experienced

    shipboard, commercial or Navy / Coast Guard Chiefs copying CW and you will see two things without exception: They're not wearing modern-style hi-fi cup-type

    receivers, and the headset receivers are not resting on the ear. The receivers are resting on the cheekbones. You hear the signal through bone conduction. That way,

    if an unexpected loud signal comes on and blasts you or you hear a sudden heterodyne, you're not gonna blow your ears out. You merely have to turn the audio

    up a bit from from where it would have been before, resting on-the-ear. Old-time Navy Sonarmen wore them that way for same reason.


    Lots of hams, understandably, are proud of their high-quality high-fidelity- reproduction , high-cost headphones. But if you're trying to copy a signal that is less

    than 100Hz wide, do you really want to be hearing everything from 100Hz thru 4kHz? Or maybe flat 2.3kHz bandwidth? The headsets above are not hi-fi and

    designed that way purposefully. Most have several peaks of natural resonance that further act as a desirable natural filter. Ultimately, the filter you need

    to cultivate is located between the ears. Doesn't run on 2 penlight cells. Noise-cancelling and runs on Raisin Bran.

    Pick up a good set of phones at a hamfest for $15 or less (Not more unless almost-new) And make sure it's got a good cord. The standard cords are made

    from tinsel-wire and difficult to repair ands impossible to replace. Good cord is worth more than the cans.

    Good luck out there, CW guys and gals.

    Where did you find these?

    I use a pair of JRC 'phones designed with a limited range for communications use. They cut out high frequency noise
    which distracts from CW signals.

    They cover my ears thus reducing ambient room sound. They are monaural. They may still be available new.

    I also have an inexpensive set of Telex on-the-ear mono headphones designed for speech reproduction use in
    schools. $15 including shipping new on ebay.

    The question of dual watch with stereo phones is relevant. For that use I use any of several hi fi headphones I have. All
    have the disadvantage of too great a frequency response so that high-pitched noise is evident where it is not with the
    limited-frequency-range phones.
