There are many more portable players by TrekStor than the i.beat 500 supporting ogg vorbis.
Please add products to the main page.
I would like to know which Players can record in OGG?! -- 184.108.40.206 17:03, 26 Dec 2004 (PST)
Pretec Allegro may need firmware update
I recently purchased a Pretec Allegro, but was unable to play Oggs for three months, until the firmware update was made available on 14 or 15 March 2005. Now it works well! (So far, listening to -q3 Oggs). I'd hope that units purchased after this date already has the firmware update, but you never know. Installing the update is as simple as placing the .rom on the USB-storage-device media (eg flash disk), starting up the unit, and pressing the play button. -- Hugo van der Merwe
- How much battery runtime do you get playing Oggs compared with playing mp3? Phr 02:05, 27 Aug 2005 (PDT)
Any player with SD-Cards
Every single ogg-capable portable player out there seems to come with built-in flash memory. Which is stupid, because I don't want to fire up my computer and plug in the player every time I get tired of the tracks on my player. Plus flash memory has a limited lifetime (write cycles) and so does your player with built-in memory. The same applies for built-in rechargable batteries.
Now when would you ever need to buy your second device without any moving parts if you could just change flash memory and batteries? Ok, that's the industrie's point of view but not mine. I want to go on vacation with music and batteries for one week of non-stop music - without a power source or computer nearby.
So, any hint to where I might find a portable audio player that can play back ogg vorbis files and uses SD flash cards (and preferably AAA-batteries) would be greatly appreciated.
The Pretec Allegro is not the slickest player out there, it's LCD backlight seems to give off a high-pitched whine, which not everyone can hear (it kind-of screams in my ears though, so I put the backlight timer on 1 second so it doesn't scream too long). It is, however, the only one I now know of that can play Oggs, and uses removable media. If you want a nicely portable device, you have to use Pretec's "iDisk tiny" usb flash disk, the only thing that will fit inside. You can also, however, connect some USB SD-card reader with it's cable, then listen to Oggs off of SD. A little unwieldy, but, it works, and is the only thing *I* know of. (I stopped following developments in December though, when I bought it...)
Samsung's Yepp Ogg Vorbis support
JoshuaRodman wrote regarding the yp-t7z:
- I received such a unit. It plays oggs encodd at -q 4, 5 and 6 without error that I have noticed. However it seems underdocumented. It plays the files in an order which is neither alpha sorted nor numeric sorted, and it does not support ogg tags. -- JoshuaRodman (March 28, 2005)
- I've investigated more. Some music encoded at even -q 5 will break up or cause difficulty. I suspect these pieces have bitrate spikes. As for the ordering, the YP-T7 plays files in 'readdir' order. That is it does not sort the files out of the filesystem at all. In practice, this means it will play the files in the order that you add them to the directory. If you are a windows user dragging and dropping the files onto the player, this problem will not affect you. A linux or possible Mac user may need to do minor scripting to alleviate this issue. --JoshuaRodman (April 13, 2005)
Spaz added for the YP-T7Z:
- After using the newest firmware I have had no issues playing OGG files. Any lockup or playback issues I had experienced went away. --Spaz (Dec 23, 2005)
Ulrich added for the YP-MT6Z:
- I think my manual says the first 8 characters of a filename are considered for sorting. As my files have the "tracknumber" tag, I wrote some Perl script that prepends that number (two digits plus a space) to the track names when being copied onto the player. I'm not sure about decoding problems, but there may be some. I encoded my files at q6 or higher.
- The chip inside seems to be a Sigmatel STMP3400M, natively specified for MP3 with addon codecs.
- It would be great of Samsung Europe would release firmware with release notes (the Korean site has newer firmware, but no English, really!). There's also some inoffical newer firmware around, but also without any release notes. Official firmware is 2.122 (on my player as delivered and on CD and website). --(Ulrich on 2005-1027)
- Two questions: 1) are ogg tags not being displayed even when the Tag option is toggle to On in the settings menu? 2) how does it handle -q 4 and -q 6 — is it just -q 5, or is it -q 5 and higher/lower? — Saxifrage 01:07, 14 Apr 2005 (PDT)
- I have seen no evidence of vorbis tags being supported; they are not displayed. I have generally encoded at -q 5 as an attempt to stay inside the "supported" bitrate boundaries. I find that the bitrate and breakups are not directly correlated, but somewhat related. This is no surprise if the problem is CPU time exhaustion. I have not found any particular quality encoding to fail either reliably or often. In general, speeds above the stated maximum supported bitrates have seemed to work fine. No lockups of any kind have been encountered. Incidentally, over 90% of my ogg files have been processed by vorbisgain. --JoshuaRodman (July 5, 2005)
I just bought one of these and I'm baffled by its erratic Ogg support. Firmware version 1.541 seems to support tags just fine, though I haven't noticed the alpha-sorting issue (haven't looked). However, I find that it can't play all my Ogg files (freezes when it tries to load the file), and there's nothing systematic that I've found to account for this. It plays some files I encoded Jan 29-Jan 30, 2005, but there are files that don't work before and after that date. The files that work so far were encoded with nominal bitrates of 128 and 192, while others that don't work were at 160. All encodings have used the same program (Grip under Linux). Ogg files that I've encoded with oggenc directly for testing purposes at 160 nominal bitrate work just fine. There's just something about most of my existing files.
I've emailed a support request to Samsung Canada, so I'll report what I find out then. Meanwhile I'm doing a bunch of rips with Grip to test different nominal bitrates. Saxifrage 10:53, 12 Apr 2005 (PDT)
- Results from my experiments with different nominal bitrates are summarised in this table:
|Tags||none||tag*||tag + replaygain||replaygain|
- * "tag" means just the regular complement of artist, album, title, year, and genre.
- "?" indicates that the case was not tested
- My conclusion is that the Samsung YP-T6 can't handle Ogg Vorbis files encoded at 160 nominal bitrate if ReplayGain tags are applied to the file. Note too that I tested a file without real RG tags, but with the normal tags plus tags with different names than the standard RG tags but with the same name-length and same length of arguments; this was to isolate whether it was a ReplayGain-specific bug or a general tag-handling bug. Thus, I suspect that the problem is a buffer overflow in tag code of the firmware. Note that I have only tested files encoded with nominal bitrates, not files encoded with oggenc's quality settings.
- The few files in my collection that have worked were encoded at different bitrates (either 128 or 192), but unfortunately the vast majority are 160, and I need ReplayGain to be able to listen to my collection on the PC without constantly changing the volume. As a workaround I may write a script to strip the ReplayGain tags as they're moved to my player, but this rather sucks. — Saxifrage 12:36, 12 Apr 2005 (PDT)
Samsung appears to have model bumped the yp-t7 series with the yp-t7j series. The spec sheet does not mention OGG/Vorbis as a supported file format. This seems a real shame as the t7 worked well. Does anyone have anything more conclusive? JoshuaRodman 08:26, 6 January 2006 (PST)
- I (Gav) own a Yepp MT-6X and I don't come to the same conclusions. I tried to remove the Gain tags and it didn't improve anything. Here are some tests I made :
|Encoder version||Filename||Nominal bitrate||Playback test|
|Xiphophorus libVorbis I 20000508 (1.0 beta 1 or beta 2)||01 - In Tenebris.ogg||unset (160 kbps)||KO|
|Xiphophorus libVorbis I 20001031 (1.0 beta 3)||01 - A Day Without Rain.ogg||160 kbps||KO|
|Xiphophorus libVorbis I 20010225 (1.0 beta 4)||01 - Sunday Bloody Sunday.ogg||128 kbps||KO|
|Xiphophorus libVorbis I 20010615 (1.0 rc1)||01 - Remede.ogg||128 kbps||KO|
|Xiphophorus libVorbis I 20010813 (1.0 rc2)||01 - Devil's Haircut.ogg||192 kbps||OK|
|Xiphophorus libVorbis I 20011231 (1.0 rc3)||01 - Encore Une Chance.ogg||112 kbps||OK|
|Xiph.Org libVorbis I 20020717 (1.0)||01 - Inferno (Unleash The Fire).ogg||160 kbps||KO|
|Xiph.Org libVorbis I 20030909 (1.0.1)||01 - You Will Be a Hot Dancer.ogg||128 kbps||OK|
Yes, a 1.0 file fails... I also tested a 8 second file encoded at q1,q2,...,q10 using 20020717 (1.0) and it worked for every quality ! So not every 1.0-encoded file fails. See YeppGavDetails for details about the files.
- OK. I've done extensive tests and I can confirm what Saxifrage suggested : there is indeed a buffer overflow in the tag handling ! When the framing bit of the tag header is at offset >= 0x18C, it fails. If it is at exactly 0x18C, it reboots or freezes. If it is at offset > 0x18C, it always freezes. This was tested with firmware 1.101 and vorbis encoder 1.0.
- The file encoded using libVorbis 1.0 in the table above has a too large tag and that's why it fails.
- In summary, the Yepp can only play Vorbis when it is encoded with libVorbis version >= 1.0rc2 AND when the framing bit of the tag header is at offset < 0x18C.
I've got this model with 256MB of flash memory, and unlike above, I ran into problems when I tried to play very-low-bitrate files (< 64kbps, CD format). I encoded them using aoTuV-beta4 experiment version from aoyumi (which creates (or should create) perfectly standard and conforming files), using command-line oggenc under linux. The qualities I used for these problematic files are -q-1 (~45kbps) and -q-2 (~32kbps), and when the player tries to open the file it freezes, but for qualities from -q0 it works perfectly.
Apart from that, I've had no real problem before, using mostly -q6 files from RC3 and 1.0, without tags or with standard ones. Sometimes the sound is distorted a lot for a few tenths of seconds, it seems to be related to bitrate peaks (applauds, etc.).
Hope this will be useful, anyway thanks for the investigations on this player, I also realized the lack of information on this player's ogg support. Superdupont 16:49, 2 Aug 2005 (PDT)
Edit: firmware version: 1.543
The YP-T6 seems to be almost identical to the Trekstor i.Beat Cube.
The YP-T6s sold in the US sports an FM Radio with 16 saved settings and automatic station search. Recording from a radio program to MP3 is possible. At least the German version of the YP-T6 does not have an built-in tuner.
The German web site has moved it from from "MP3 players" to the Archived MP3 players section, while the US and UK site lists it as regular model. I don't know if this indicates that Samsung is about to stop production of the T6 or if there have been problems on the German market (like restrictive radio emission laws, see built-in tuner section above).
I'am not sure what's inside this player. May be it's a STMP3505. With firmware 1.200 it plays Ogg Vorbis, but not at very low bitrates(-q-1 and -q-2).nostromo 4 Nov 2005.
Firmware 1.200 is a bit difficult to find, googling by file name (YP-53_V1.200.zip) gets a single relevant result: Korean page with a link to the updater. If it disappears, contact me (inejge) via this site (E-mail this user on the linked page).
The new firmware is much nicer than the previous release (my player came with V1.024):
- It plays OGGs, starting with -q0.
- The main screen is better organized.
- Menus are cleaned up (and with more eye candy).
- Non-ASCII characters in tags are displayed properly (tested with OGG).
Note: if you are encoding OGGs at -q0, don't try to set the lower bitrate limit to 64 kb/s -- the player can choke on managed bitrate files. Nominal bitrate is all that counts.

Firmware 2.242: Plays Vorbis OK with tag support. Tested with aoTuV beta 4.51 and Xiph.org Vorbis between -q2 and -q8 (mostly at -q5; manual claims support from -q0 to -q10), no lockups so far. Experienced unusual distortion at one point of a particular track (loud, percussive synthetic "thunderclap") at -q5, decreasing with increasing -q value; this appears to be caused by a spike in bitrate, solved by passing encoding options

Apologies if this is the wrong place for this; I'm new to wikis.
The UniBrain iZak was added, then removed recently, with the comment that it doesn't claim to play Ogg Vorbis.
The FAQ is available here: iZak FAQ and Question/Answer 22 says:
'22. Can iZak™ support OGG audio files?
Yes, iZak™ fully supports OGG playback using the latest firmware.'
- I was the one that removed it. In their specs linked from the main page, I saw that they listed only MP3 and WMA support for music formats. Obviously they need to update their promotional material! I went ahead and added the iZak back in, making a point to mention that the most current version of the firmware now supports Ogg Vorbis and linking to their FAQ as evidence.

- Splendid. I didn't want to just stick it back after it had been taken out.--Ipl 05:14, 5 May 2005 (PDT)
This inexpensive player from Entempo lists Ogg as a "Supported Audio Format", but the device will not index the Ogg files into it's menus -- let alone play the files. Tested with both the stock and most recent firmware, May 29, 2005. Vendor has been contacted.
Lexar LDP-800 dropped
It seems that Lexar have abondoned the LDP-800. The following was posted by a user on dapreview.net " Unfortunately, lexar will not offer the LDP-800, but will focus instead on its existing LDP Players that already offer appealing features and benefits to meet a variety of consumer needs." Shame.--Ipl 06:15, 22 Jul 2005 (PDT)
There's more info on that dapreview thread that indicates some confusion within Lexar. Currently, it looks like the release is going to happen in early September.
Update 2005-11-11: after inquiries to Lexar's "new products" personnel, I received a telephone message that the LDP-800 will definitely "is not going to see the light of day." Ask me if you want details. I agree that it's a shame since this looked to be an outstanding product. --dfavro
Hong Kong Dream-tech Electronic DT-202, works? please confirm
http://hkdream-tech.com An ebay seller says that it can reproduce OGG. This is unconfirmed. In the manufacturer web it says: MP3, WMA, WAV, DMV and etc.
Some webpage also says that it works on Windows, Mac and Linux. Also unconfirmed. Further investigation required.
Trekstor i.Beat Cube
This player seems to be very similar to the Samsung Yepp YP-T6, possibly with the same problems regarding Ogg playback. Trekstor has moved info about this player from "MP3-Player" to the "Archive" section which propably means that it is not produced anymore.
The Muzio jm300 / jm-300 does NOT play ogg
NB this is the jm-300 (not 100 or 200)
I bought this a month ago. I've been unable to play ogg files on it. It simply shows these as 'etc' files and skips over them.
Pitty really, this was the main reason I chose this player.
I've seen lots of discussion about the muzio playing oggs, is there anybody there who owns a jm300 and is actually playing oggs ? I can't help think I've juts missed something basic.
Layout of the PortablePlayers list
Wouldn't this list be easier to read if there was a seperate heading for each product, sorted by manufacturer? --Blenda 09:13, 11 January 2006 (PST)
