Single Vs. Double-prong Headphones

Thu Jun 15, 2006 1:44 am

While most airlines have eliminated the disposable hollow tube headphones, why some airlines use single-prong headphones while some use double? IMO it would make sense for IFE systems to all use single-prong headphones, as those are nearly universal on electronic devices.

On Delta, the Song aircraft use single-prong headphones, while the rest of the fleet uses double. With the new IFE system arriving, I would guess the fleet will switch to single-prong headphones, with the exception of the MD-90s.

Another question: Will Delta's widebodies use the Panasonic eX2 system? The eFX is used on the 757s, and is designed for narrowbodies.

LOL. Think about what you just said for a moment and see if the answer becomes apparent (and remember that most US airlines charge for the headphone rental). It's also why Delta (and maybe everyone else, I don't know) changed their policy from charging a headphone fee to charging an entertainment fee (2000/2001).

The Delta aircraft I used to fly in had single prong, and when the FA saw that I was using my own headphones, she barked that if she wasn't in such a good mood she would have charged me the rental fee. This was included in my letter to Delta where I pointed out, to their credit, the only good thing they managed to do on that flight was not crash the plane.

Delta's response was very good - kept me as a customer actually.

Just on the Delta front, the only good thing I got from flying Delta was a pair of headphones with a double-prong to single-prong adaptor (free because we sat on the ground for 3 hours while a "small" maintenance issue was "looked at")...

It seems to me that of the DL aircraft (all DL no song) I was on it was split two prong TS and single TRS.

Now a good reason for it? Since many airlines have changed to selling headphones (vs. renting) and making IFE complimentary...I can't think of one.

The Connexion by Boeing reps were passing out over the ear headphones
with retractible prongs as part of promo for pax on KE's SEA-ICN 777 flights
that have the CBB service about a month ago here at SEA.

On a recent SK flight, they passed out 3 prong headphones. I guess it had something to do with the noise cancelling feature of the headphones. Noise cancelling + earplugs = no noise.

DAL and others have used double prong for years in an attempt to get you to buy. Other carriers have moved to the single prong which matches your walkman headphones. However biz class on more than a few uses two prongs diff size as one is for the audio and the other is for the noise canceling.

There's noise, alright, and it could still be painful to the ear, but you wouldn't know it until it gets to that point, since the noise is still there, but no sound is produced, due to both the 'normal' noise and white noise cancelling each other's frequencies out.
