Hi, I visited this site extremely rarely in recent years. I canNOT find any shopping Guides for headphones, say under $100, buds, foldable, etc Where are the latest Christmas (2019) Shopping Guides or Recommendations?

Thanx. I will follow your suggestions. Incidentally I've found this: here iPhone Not Charging? Clean Your Lightning Port and What to Do When Your iPhone or iPad Isn’t Charging Properly ( … Check Your Charging Block, Inspect Your Cable)

My 7-year old ODAC is :L3000: as dead as a door-nail as was Old Marley in 'A Christmas Carol'. PS.1 What is life expectancy of the ODAC (or the O2 amp)? P.S. 2 I have the O2 and ODAC as two separate units from JDS Labs. Everything is quiet, no hiss, buzz, or any kind of sound. Therefore, I...

Thank you very much. So, certainly teenagers with or without golden ears, or even audiophiles, would not hear any difference. By the way, I have forgotten to mention my setup: laptop (Windows 10) ----> ODAC ----> O2 ----> Beyerdynamic DT 880 (250 Ohm) On another matter. Last week I did...

Hi, I have bought both the Triad P/N WAU12-200 - 12VAC, 200mA and the current one 15VAC, 500mA from you for using in the USA. Not having golden ears, I do not hear any difference in sound quality while using either of them with my Beyerdynamic DT 880 (250 Ohm; 2005 Edition) headphones. Are...

Hi, Thank you for the link. Incidentally, recently I checked out the Logitech M570 Wireless Trackball (no. 4 on the list). It's large but that trackball feature is a pain in the neck - I returned it after a couple of hours of struggling with it. That trackball is so clumsy for me. By the way...

Hi, I've got the JDS Labs O2 amp as a standalone unit which I had bought in Feb 2013. I have just bought a new Tenergy 9V NiMH Battery 2PK and would like to replace the old batteries ( which were installed in Feb 2013 by JDS Labs). Since this is the first time that I am planning to install the...

Hi, I am a novice-casual video game player. I have got large/big hands. I would like to buy a gaming mouse (say, in the rage of $40-60) for sim racing: Assetto Corsa, Project Cars, Grid,... I also play flight simulator games: DCS World (F15,...), Falcon BMS 4.33 (update 3), Ace Combat Assault...

  Hi,     I am not experiencing any  popping sound when the 02 gets low battery. Simply, at a certain point the batteries are 'dead' and the O2 is absolutely quiet. - No popping sound, hiss, buzz etc. et all.  Is this normal?    Ha, ha, ...   This is exactly as if I turned the O2 off.  ...

  Yeah, thanx for the following advice:       I've heard that people put their batteries in the refrigerator when they don't use them for a long time.

  Thanx a lot for your comments.   By the way, I've edited  my previous post because of this:     From http://www.head-fi.org/t/737065/review-sansa-clip-vs-clip-zip

      Thanx to H20Fidelity  and  castleofargh.   You both explained things that I had not known at all.   Although  this thread is about rockboxing Sansa DAPs: Clip+, Zip, ... I think that the batteries-related stuff is relevant here for the following reason. I have read on this site...

Reading about  all that drama caused by  rockboxing the Clip+ I am postponing rockboxing  of my Clip+  until  further notice.       Well, I've got  battery related questions:   - In terms of the  the Clip+ batteries' longevity  is it better to run them down - until the Clip+ shuts off on...

As a rule of thumb always    include the O2 (along with the ODAC) in your search for an amp under $300 (or even much more expensive).    I'm using my DT 880s (250 Ohm) with the JDS Labs O2 along with the ODAC and my Toshiba Satellite laptop.  I am really very happy. The system sounds great...

No, you are terribly wrong. The O2 and ODAC are very popular here. Way over one year,  I bought them from JDS Labs  - what a great place to buy  -  and I am very happy. I'm using the O2 and ODAC  with my Toshiba Satellite laptop and the DT 880 (250 Ohm) cans. The system sounds great.  ...

Yeah, Germany's best team in the world! Congratulations.   Although I am not German I am happy because finally a European team won FIFA World Cup  outside Europe -  in South America -  more importantly,  in Brazil.   In the final, Argentina tamed Germany. I was surprised. I thought that...

    You were very close to winning your bet, if only Ozil  had scored in the 88th min.   Instead we have Germany beating        Brazil  only  7:1

The 'old' age of the Holland's  attack-players  could be a disadvantage in their sixth game:   Robin van Persie  -    30 years old Wesley Sneijder   -   30 years old Arjen Robben       -   30 years old Jan Huntelaar       -  30  years old Nigel de Jong       -   29 years old   (and also...

In 1974, FORTY years ago, Germany defeated  Holland 2:1 in the FIFA World Cup  final. Shall wee see Germany vs. Holland in the final again? But this time without Johannes Cruijff,  "Johan" Neeskens and Gerd Mueller, Franz Beckenbauer, ...!   Will Holland take revenge on Germany or the...

  I second it. Belgium was a much better team. The USA is not  there yet.

    Hi, if it is slightly bright at all, it is pleasantly bright, to my ears. I enjoy   the ODAC and the O2   with my DT880s very much.

    So is it 50 mA or 125 mA?     Sorry for being  curious.

  I am very glad that I've found your post. Very informative. The most important for me is this:       I am not interested in any surge protector (with filters) any more.   Thanx.

  Thanx, this ENOB explains a lot. Let me ask a naive question. Does ODAC have a 24-bit DAC chip? Assume it does, then what kind of noise is causing the loss of about 5 bits: generated by the ODAC's  electric power circuitry implementation and parts, ... or some other noise/distortion ... ? -...

  Hi Purrin,   My ODAC sounds excellent from my modern Toshiba Satellite (the S-series, released June 2012), so the USB power is good (how good?)  in this particular  case.   Anyway, one can use the ODAC with the Vaunix hub   (recommended by Currawong) or the iFi iUSB, and so on. What...
