Grados are not really designed for outdoor wear. They could be re-designed for such, but they'd need to build in strain reliefs, jacket the cables, shorten the cable a bit, and find some way to keep water out of the transducers without losing the "open" quality that make Grados sound better than closed headphones.    For the life of me, I don't understand why the major manufacturers do not jacket their cables and put on strain reliefs. It would extend the life of the...
My Martin built Turbulent X driver 'phones are in the shop for re-wire, and I hope to have them back later this week. I sent them off to Jason Ambrose for a full re-wire and am getting a strain relief added in.    The Sovtek Military Spec "audio" tubes are incredibly smooth, stable, noiseless, and designed for much harsher conditions than they can ever experience in a Little Dot MK II. Stuff designed to be dropped at height into the ocean, on a weather balloon etc. are...
The cord frayed at the splitter and I returned them to Koss after registering them on the warranty page. Enclosed a check for $9 US and a brand new pair showed up in the mail in a plain box and a plastic bag about ten days later. These are my "outdoor" headphones--the Martins don't leave the house. The Koss PortaPro are so comfortable that I frequently fall asleep wearing them. Sound quality is good though certainly not up to the level of a Grado or Ultrasone.   They are...
I have spent more than a thousand hours with the same pair of Soviet 6BE6 tubes in my LDIII, , fed by a Turtle Beach DSS2, a Carver TX11a tuner or an IAudio 10. Headphones are my Martin Cocobolo shell Turbulent X cans. The electricity is via a dedicated 15 amp circuit with a Tripplite hospital line conditioner.   Power tubes are Soviet 6N6P mil-spec matched set from the 1970's. These have been in this amp for the past two years.   For Big Band, Swing, Folk, Spoken...
As an amateur radio operator, I have more than a few receivers and most of them can be overloaded by switching power supplies and wireless routers, which generally scream all the way from 10 KHz to 30+ MHz. Computers are a rich source of harmonics, odd and wandering digital noises. In cracking open more than a few computer cases, one can see the places where the various filters would be if the manufacturer had included them.   All of this is perfectly legal under Part 15...
The notes say he used Turbulent X drivers. I have never heard any of the other transducers in the Turbulent line, so I have no way to compare them. Given how many differences there are between the Alessandro MS1 that are my previous cans and the Martin headphones, it is impossible for me to state with any certainty that the drivers are the most relevant change. It could as easily be the cups. What's there from the cable in the audible range (40 Hz to at least 18 KHz) s...
Steve Guttenberg at CNET says the Mad Dogs are excellent with two different tube headphone amplifiers he has tested, so I suspect the LDIII would excel with these cans as well.
Pictures will be posted as soon as they can be shot and gotten back from developing and scanning. I shoot 120 size film (6x6 cm) with my Rolleicords and 4x5 inch sheet film in a Press Camera.
My first purchase was a Koss Portapro for travelling. Grados are not suitable for the Streets of Seattle. Much better build quality and durability than the Skullcandy phones that fell apart after ten months of gentle usage.
The Martin cans arrived late this week! Phenomenal quality construction. The red and black cocobolo chambers are magnificent, as are the bare aluminum mounts and the leather headband. Turbulent X drivers inside. The wiring is basic- black 22 AWG silver plated copper with a Paiiliccs 3.5mm plug.   The bottom line though, is how it all works as a unit. It is beyond anything I could have wished for. Listening fatigue is absent. Sibilance is not relevant-it isn't there....
