so, with my new powerbook, I wanted to buy some bluetooth headphones.
I did search the forums, but all the threads were somewhat old.
so, now I ask again, are there some good "Hi-Fi" BT headphones yet ?

if so, any experiences with them ?

thx.

Ooooh, if there are I will buy them in a freaking second!!

I really enjoy music, I currently have a ver good pair of Sony headphone, yet -as with all Hi-Fi headphones- they have a ~3m cord. My powerbook has built-in BT. I would really like to get rid of the cable

No BT headphones exist. It will be a while before you get wireless HiFi BT headphones. All we currently have is IR headphones.

beleive me.

end of story

These are the only ones I know of...

Those don't count. They are a combination of a mp3/wma headset that also doubles as a BT "headset" set for a computer. Although technically one could transmit music over BT with this system, it will sound like a telephone call as that is all the BT headset profile supports. The music must be played "locally" on the headset - which if you ask me, looks like a real crappy one.

This brings me to my final point. There will be no BT HiFi headphones until there is a profile to support it, or a company comes up with a proprietary hack, which is unlikely.

They need to work on the streaming technology because the Bluetooth 1.1 spec chipsets in our PowerBooks don't have enough bandwidth to support uncompressed audio, so there needs to be some extra steps inbetween. That plus as mentioned above no current profiles exist for hi-fi audio over BT.

One could easily piggyback and audio stream on a BT serial connection - max is something like ~768KB/sec. One could get a few good AAC stream on that in theory! - The problem lies in the custom hardware required to play an AAC stream from a serial port and whatnot. By no means impossible, just more than companies are willing to do right now apparently...

My guess is the problem is with battery life. Current BT headsets only last about 2 or 3 hours. Considering HiFi headset would draw more power...

I might be wrong, but I think I read somewhere that BT has a peak bandwidth of about 76x KB/s ... a stream of uncompressed audio, ie.a CD ... is sustained 172KB's/s ... apparently BT enough bandwidth for it.

I might be wrong on the peak bandwidth though.

Bluetooth's peak data rate is 768 kilobits/sec, or less than 100 kilobytes/sec. Uncompressed CD audio is 1,411 kilobits/sec, or 172 kilobytes/sec.

ok...shout at me if im being really dumb here but cant someone bring out headphones that use WiFi to pass the music across without wires?

Surly low power WiFi would transfer music across at a bandwidth that gave excellent quality sound

just a though

[normr]

Heck,

I just wish someone would make a BT trackball already.

[Crusoe]

Dees Guyzes seem to have a chipset and released a model some time ago, no link on where to buy though they have a sales@ email.

I'm looking for something that using BT to transmit to AC powered speakers preferably with BT built-in (don't want to deal with recharging batteries). Have another thead in periphs with no results.

Bump. There have been a rash of new ones, some from the same OEM:

Toshiba,
HP,
Logitech

and iCombi, Bluetake, and others. The only thing is that all of them are Bluetooth 1.2, which should provide barely adequate streaming audio--which I've also read about on Apple's discussion boards. But the question remains, does anyone have experience with reliable, great-sounding, battery-friendly, and good-looking headphones/headsets? Or any combination of these qualities? I suppose we are waiting for Apple to update the PowerBooks to be more compliant, yes?

Update Oh. Uh, Om Malik seems to have paired his Toshiba just fine. Um.

I am curious why can't we use the Sony-ericsson or the Nokia BT headset, though they are not Hi-Fi.

[brokenjago]

Aren't there any Wi-Fi earphones? Am I going to have to make one out of an Airport express or something? (that would be hilarious looking... I might actually do it, if there's nothing decent avaliable.)

I have been following this technology for some time. The problem is that Apple PBs, iMacs, etc., with built-in Version 2 + EDR BT do not yet support the A2DP profile required for HiFi over Bluetooth. Apple will likely have to release a firmware update to support this profile. My guess is that this will happen when BT comes to the iPod. A few Version 2 + EDR BT USB adapters from Toshiba, Princeton and others do support A2DP and headset profiles on PCs but Apple (in its infinite wisdom... err stupidity) does not allow its BT Firmware updater and BT software to support the headset profile (on them. The only supported third-party adapter from D-Link is Not version 2 + EDR and does not support A2DP. So although there are BT HiFi headsets coming on the market (Toshiba's is very nice), they can't work either with Apple's built-in Version 2 BT or third-party adapters on Macs. This is an amazingly stupid state of affairs for a company big in music and entertainment that was so far ahead in putting Version 2 BT in its machines and then deliberately cripples the functionality.

[iomatic]

So you're saying it's still stereo, just not very good quality? Om says it works, so, it works, just not well... is that the correct picture?

[rocky2]

It's not stereo unless you can find a third-party BT USB adapter (maybe Porto BT Adapter 2.0) that is at least BT Version 1.2 (and preferably version 2) that supports the A2DP and headset profiles AND that is supported out of the box by a Mac without built-in BT (can't have two BT devices in one Mac) AND that is paired with headphones supporting the A2DP profile (new Toshiba hifi stereo headset).
Using the built-in Mac BT hardware will NOT give stereo because it does NOT support the A2DP profile. If Apple ever releases a firmware upgrade for its built-in BT hardware to add A2DP profile support, stereo will be possible.
Using the only Apple-supported third-party D-Link USB BT adapter (DBT-120?) will not work because it does NOT support the A2DP profile (and likely never will).
There is a report in the Apple Discussions (BT Othr Devices) about someone getting audio from iTunes out of a SE HBH-620 headset (BT version 2) from the Porto BT Adapter 2.0 (version 2) which is a good sign but a request from me for more information on the specs of the BT adapter have yet to be answered.
