Blackberry passport silver edition and external audio DAC FiiO E17

The FiiO E17 works on my BlackBerry Passport silver edition running OS 10.3.2.2474! I connected it to an USB to go cable and could hear music e.g. from the Spotify app (Amazon Android app store).

The setup is shown below. I used an USB hub cable as this is required to run the setup at iOS devices. But I guess a normal USB cable should work as well.

Blackberry passport silver edition a working horse for productivity

If you commute like me in a train or other public transport, you might like to use the time to read and answer e-mails, write meeting minutes and other business related work.

So far, I was using touch screen devices for that. I found out, that I was struggling with the touch screen keyboard on longer text inputs. I also used an ipad with external keyboard. But it was only comfortable if you have a table to write. So, I decided to give the blackberry passport a try. And so far, I really love it. I used blackberry in the past (my latest was the Bold 9900) and I am owning a playbook (which has a similar operation system like the passport).


No chromebook innovations anymore?

From my post frequency (which dropped recently) you can see there are not too many exciting news anymore for Chromebooks. The systems are running well. I am personally still using my lovely Acer C720 Chromebook (I type this article on it).

If google (or Alphabet) needs some input for innovations, here is my list:

- Make the chromebook Android compatible. Some apps are ported from Android already. Not many though. Why not having a virtual machine on Chromebooks running android?
- Chromebook in the cloud. All the Chromebook settings etc. are synced already today. Why do I need a Chromebook to run my environment. Why can I not use any browser? A virtual Chromebook (available on all browsers) might be cool to have access to the lovely Chromebook environment from everywhere. Jolicloud Linux was a great example into that direction.

Please add you innovation wish list in the comments.

Chromebook Pixel 2 launched

Just after Apple having announced the new Macbook 12inch version, google announced the new high-end chromebook Pixel today.
It is mainly upgraded in processor power and battery life. It comes with the same USB-C connection as the Apple Macbook with 12inch screen. Price is slightly reduced, but still hefty starting at 999 USD. There is a LS "Ludricrous Speed" Version with Intel i7 and more RAM for 1299 USD.

Have a look at the very honest review at The Verge.

PDF tools for a cup of coffee (or free) on chromebooks

Do you still remember the times when you had to buy expensive software just to get small things done? E.g. Acrobat software of Adobe just to manipulate pdfs? Do you remember that operating systems and computers were expensive? This time is definitely over.

With a chromebook and a cool cloud tool you can manipulate pdfs as well. Have a look at smallpdf.com. The best tool I found to manipulate pdfs in many different ways.
Do not forget to donate a coffee for the programmers!

Update: Google Music upload from chromebooks

So far there was no way to upload music from a google computer (chromebook) to google music. Which was somehow odd.

Text below is obsolete now. Google music is now supporting uploads from chromebook (even from the gdrive). Thanks to the developers. More details at google plus post here.

Now, at least a lab version of the upload exists. So, there is no download (upload) manager needed anymore (which was until not recently compatible to chromebook, only windows, mac, linux was supported).

Here is a step by step tutorial for you.

Cloudbeats, the iOS app to stream audio files from the gdrive (flac and other formats)

Cloudbeats is the only one iOS app so far which allows streaming of audio files from Dropbox, Google Drive, Box, OneDrive, Mediafire, ownCloud.

You save a lot of mobile storage space on your mobile device by storing audio files such as flac / mp3 in the cloud (see my blog post). Then you can hear your music by multiple devices on all operating systems. For iOS the cloudbeats app is needed which does a nice job. Chromebooks can read it nativly, for windows and mac there are many players available.

I use it to enjoy lossless sound in the office / bed or other areas with WIFI access (the app can copy files for offline usage though)  from my library on my gdrive. No need to sync files anymore.

You can get cloudbeats from the Apple app store.



Use cases of gdrive storage space: audio streaming

With your chromebook you probably received a lot of storage space on googles gdrive. Either 100 GB or recently 1 TB as mentioned in my blog. This is a lot of space. I would like to give you some ideas for use cases.

Todays use case it is about storing your audio flac files (uncompressed audio format which can even hold high definition audio with sampling frequency and resolutions higher than CD, which is 44.1kHZ / 16 bit). MP3 was invented to reduce storage space as it was limited that time (in the ninetees). Bandwidths of streaming were limited as well (I just remember my modem with 56kbaud). MP3 sounds great considering the 11times compression factor, but today we can afford to store and stream full quality of the audio information.

For mobile devices the flac files are still huge. An CD music album can be up to about 500 MB / 0.5 GB big (with high definition audio the number is growing even more). For an iphone or other mobile device with limited memory space you can store not too many albums. Same situation we have with the chromebook. They are usually equipped with 16/32 GB SSDs only. So, better do not use as your flac library. If you cam limit your flac consumption to WIFI equipped area there is one nice solution to the issue: cloud storage.

If you rip the CDs to your gdrive you do not stress your storage capabilities on your devices. Unfortunately so far it is not possible to RIP CDs on a chromebook. But other OS can rip CDs with free software like foobar to the gdrive. Then you can enjoy it on your chromebook by using the internal audio player (see my blog) by streaming it from the gdrive directly.

The cheapest DAC and smallest solution for digital audio on iOS devices (ipad, iphone) with lighting connection?

I already reported here in this blog about my FiiO E17 Alpen Portable Headphone Amplifier USB DAC which can be used as a very audiophile USB soundcard and headphone amplifier, even on chromebooks.

The issue so far was, that it was not easy to connect it to recent iOS (ipad, ipod, iphone) devices. They all complained with an error message, that the device is draining too much power after the direct connection between the 2 devices by a regular USB cable.

There are several solutions to it, which all add a lot of weight and inconvenience. One is to convert the digital audio to SPDIF signals (needs an additional adapter which costs 50 bucks) or use a powered USB hub (needs a power source which is not available usually during mobile usage, or a battery needs to be attached).
I think I found an even better solution now.

There is a very compact passive hub which has no housing (just cables, see picture on the right). It is sold by Conrad Electronics e.g. in Germany or Switzerland and probably in other countries as well. It cost 6 EUR only. If the 3 "hubs" are cut away it even looks like a cable. I have not cut them yet on the picture below, I will cut them soon to have a very small and compact adapter.

The adapter has even the right USB connector to the Fiio E17, so there is no addtional cable needed.

To make it work, the USB charging function on the E17 has to be switched off and the hub can be directly connected. Then the music can be enjoyed. See my full setup in the picture below. Very compact, isn't it? With the removal of the non used 3 hub connectors it will behave like a short additional cable (for 6 EUR only).

If you find other sources to purchase the cable globally, please post them in the comments. I was looking for such a solution a long time and found it by accident.

The headphone in the picture below is a Philips Fidelio X1 which I recently purchased. It is one of the best in his price-class. I really like it. To be perfect it is just enhancing a bit too much the bass, but a more perfect headphone (like Sennheiser Sennheiser HD 800 costs 6 times more).

Updated: Ipad mini and Fiio E17 USB DAC compatibility (also in combination with E09)

Please read my most recent blog post on this topic which makes that below obsolete.

As I did not find many reports of the Fiio E17 compatibility with an ipad mini, I tested it myself.

The FIIO E17 Alpen USB DAC Headphone Amplifier unfortunately does not work as USB DAC in combination with the ipad mini and the camera connection kit (message "external device needs too much current") if connected directly. Even switching off the USB charging function on the Fiio does not help to overcome the current limitations given by the ipad. The docking station with amplifier FiiO E09K does not change the situation!

BUT, connected to a powered USB hub, the ipad and Fiio work like a charm. I played flac files and other content from the ipad. I found out, that even non-powered hubs work and powered hubs just need power during the connection to the ipad. Later the power can be removed. There are very compact non-powered USB hubs which allow a very mobile setups. Amazon is offering one (see picture below), I have not tested this particular one. My one is very similar by Dr. Bott.


 Some other users reported that external spdif adapters do work (like http://www.matrix-digi.com/en/products/5/index.html). The spdif signal can then decoded by the Fiio which gives a mobile solution. I have not tested this combination myself yet.

No exciting new chromebook in 2014?

In 2013 holiday time the chromebook hype was starting with Acer C720 and HP Chromebook 11 . The HP one was the most beautiful chromebook built ever (without counting the original Google chromebook Pixel which is too expensive and old).
There are nice chromebooks in 2014, but I really miss a nice designed one, a more pro one or other exciting upgrades. There are much more chromebooks available from different brands, but I am still looking for THE one which will motivate a customer with existing chromebook to upgrade.
Just dreaming: a HP chromebook 11 design (with new power adapter), IPS screen, Intel Haswell, 4GB RAM, 32 GB  SSD, 13 hours battery life would be a dream or a Pixel with upgraded hardware and 10 hours battery life. I think the announcements for this holiday season is over. Do we really need to wait for one year now or will there be a surprise coming up?
HP Chromebook 11 the nicest chromebook (after Pixel), but not the fastest.

Get the Acer Chromebook 13 from Amazon

The brand new Acer Chromebook 13 can be already pre-ordered at Amazon.

The technical data here
  • VIDIA Tegra K1 Quad Core 2.1 GHz Processor
  • 2 GB DDR3L SDRAM
  • 16 GB Internal Storage
  • 13.3-Inch Screen, NVIDIA Kepler GPU with 192 NVIDIA CUDA cores
  • Chrome, 13-hour battery life

13 hours battery life is amazing. It doubles the battery lifetime in comparison to the Acer C720 (which I still own and use to write this post).

I love my Acer C720, but the new Acer Chromebook 13 seems to be a nice upgrade.

Updated: Chromebook for Audiophiles: Acer C720 + FiiO Alpen E17 DAC + headphone amplifier

Update: Chromebook audio player plays flawless flac files now (if the CPU is not too busy).

When I ordered my FiiO E17 (ALPEN) USB DAC headphone amplifier I was not sure if it will ever run on the chromebook. Surprisingly it works as expected, just plug and play. No driver, nothing needed. Thanks to Google!
I did not mention it in my review, but the Acer C720 is not shooting HIFI sound out of the 3.5mm headphone jack. I was not expecting it though, but now with the Alpen E17 it sounds like a high end audio system for a very affordable price (if you own good  headphones) .
