Summary: I've only had this set for about a week, but the field testing has turned out quite satisfactory. Mind you, this is a very inexpensive headset combo, but it works very well and feels very comfortable. I have worked several hams and their comments to a man were "don't change anything". Good crisp full range audio in the mic, and the phones reproduce the incoming audio as well as any I have previously used.
Summary: Big difference between these headphones and the Heil traveler dual. I'm using the Koss headset for the 10m contest, using the Kenwood 480 with CW filters and with the Heil I had the sound between 12 and 1, switched to the Koss and dropped it down to 9 and I was able to hear stations that I couldn't with the Heil. On voice I get reports of a hum on my audio with the Heil but when I switch to the stock hand mic it goes away.
Summary: I haven't tested durability because they weren't put under much use.
Pros: I bought these 4+ years ago as my second headset ever and it worked well for that short duration before I upgraded to something better. Gold plated jacks, folds up easily, comfortable, good oval ear cups. Now for the sound quality, I recommend these for customer service, vocal applications.
Cons: I DO NOT recommend these for music or gaming. They have no bass punch and the treble gets really piercing at high volumes. I would consider them "hollow" sounding.
Summary: I bought this for my HF rig. The Microphone is a ELECTRET and needs a supply voltage for operation. It works great with my 746pro Xcvr. The reason for Good instead of Great is that the headphones squeeze my head. I will see if there is an adjustment [bending ?]. I get great audio reports using the TX EQ suggested by Heil.
Summary: They're pretty nice, I guess. I use them in my university German lab. I mean, I didn't get much chance to test them, but they sure make people shouting things I don't understand sound nice. They also seem like they've been around for forever, so I guess they're probably pretty durable.
Summary: The SB-45 headset provides solid performance for the price. You CAN pay more, but you won't get better value for the money you spend. Earphone receivers are clear, and full range. Microphone is HOT and clean, you may want to reduce your input volume to avoid over-modulation, but properly set the mic works well and is clean and clear. Durable build quality - not the strongest available, but should last a long time with reasonable care.
Summary: Very nice product. Very comfortable. Blocks out backround noise very well. Great acoustics----Exceptional bass Only reason I gave it a 4 out of 5 was because it doesn't have an on-line volume control.
Summary: As I mentioned before the cord is not substantial, but my desktop sits on top of my desk so there is little risk of it getting caught or tugged on to cause damage. Others may have a different experience in terms of the cord, but for me it's been perfect, just wish it was slightly better insulated.
Pros: The price, especially considering the quality. I'm nearing the one year mark on owning my pair and have yet to have any issues with this headset. Initially I had concerns about the integrity of the cord, because it is really thin. This usually means the headset should be prone to shorts after extended use. However this has not been the case to my great delight.
Cons: No major cons so far. Some folks may not like how warm their ears will get in these as well as how difficult it is to hear -anything- else even with just moderate volume. I have missed my door bell several times for this reason..haha.
