  3. I just purchased the new Beats Studio3 "10 year Decade Edition" headphone. It's functionally identical to the Studio3 I purchased from the Apple Store last December. There is a burn-in necessary for the Studio3, and the biggest change I noted (after ~24 hours) was around 3 khz. The final sound is as close to my original Studio3 as I can determine by listening - no more than one db difference. While I'm not a big fan of Apple for several reasons, their acquisition of Beats was a big plus for these headphones' physical quality and consistency. Recommended, if you like the heavy sound, or are willing to EQ it.
  4. Last night, after 22 days using this Beats Solo3 Bluetooth On-Ear headphone, the original factory charge finally ran out and so I recharged it. I averaged at least 2 hours per day listening in Bluetooth mode for the past two weeks, and 4 hours/day or better the first week, while listening and running tests. That amounts to about 60 hours by my estimate, whereas the Solo3 is rated for 40 hours runtime per charge. This battery performance adds to my other impressions of quality for this headphone. But I must reiterate that this Solo3 was purchased at an Apple Store, whereas many if not most of the Beats reviews seen on Amazon U.S. and U.K. are from customers who purchased clones from non-authorized sources.
  5. Here's a little sleeper item - a $99 USD earphone (IEM) that few audiophiles would suspect of being a good listen. And it might be, with the right eartips. It definitely is with a good equalizer. http://www.hifiheadphones.co.uk/community/threads/beats-urbeats3-decade-collection-earphone-iem-review.4529/
  6. The NightOwl has great potential in having tonality superior to most non-premium or non-audiophile headphones, but the frequency response tuning needs a good bit of tweaking... http://www.hifiheadphones.co.uk/community/threads/audioquest-nightowl-audiophile-stereo-headphone-review.4528/
  7. My full review of the new Beats Solo3 "Decade Collection" headphone - likely a purely cosmetic difference from the late-2016 original Solo3. Bluetooth == yes, Noise Canceling == no. http://www.hifiheadphones.co.uk/community/threads/beats-solo3-decade-collection-bluetooth-headphone-review.4527/

  15. This is not my usual hi-fi headphone/earphone review, but given that this was a free subscription perk from a famous source, I thought it would interesting to see how much sound quality I'd get with it. (Spoiler: not much). http://www.hifiheadphones.co.uk/community/threads/stereophile-souvenir-earbuds-iem-earphone-review.4526/
  16. The Shinola Canfield On-Ear is a small headphone of very modest sonic quality, but with an awesome aesthetic and build quality. I report the sound with a moderate level of EQ tweaking, and it is excellent. Some audiophiles don't believe that EQ will make a headphone sound better, which is all the better - just play it flat and imagine the sound that I describe ..... and it looks really great. http://www.hifiheadphones.co.uk/community/threads/shinola-canfield-on-ear-stereo-headphone-review.4525/

    MQA (Master Quality Authenticated) - Better Sound or DRM?

    Today I updated my MQA observations PDF to include (finally!) a simple example of the current DRM, and probable DRM via proprietary music player software. http://dalethorn.com/Audio_MQA_Notes.pdf

    MQA (Master Quality Authenticated) - Better Sound or DRM?

    Apple is selling the album "Radka Toneff - Fairytales - Original Master Edition (MQA)" in the iTunes store in the U.S. now, exactly as shown for the original MQA album available from high-res stores and streaming sites. Apple also sells the older edition in the iTunes store. But the MQA album is not actually MQA'd. Here is what I found so far: 1) The iTunes "MQA" files (AAC, file extension '.m4a') have a much higher playback bitrate than any of the other iTunes files I have in my collection - several hundred of them. All previous iTunes files that I know of are 256 kbps variable bit rate, and these "MQA" tracks go as high as 461 kbps variable bit rate. 2) I converted the .m4a "MQA" tracks to FLAC, as I did with the older edition iTunes tracks, and the "MQA" edition FLACs' total size is 165.5 mb, compared to 123 mb for the older FLACs. 3) I played the .m4a "MQA" tracks as well as their FLAC conversions I made with Foobar2000, on my Mac's VOX music player using the Meridian Explorer-2 DAC, making sure to try all of the bitrates provided by the Mac's MIDI settings, and never could get a green or blue light on the DAC as I get with the Steve Reich Pulse album (I have the Pulse album in 16/44 MQA as well as high-res MQA and high-res non-MQA). 4) The iTunes "MQA" tracks are 16/44 as seen by the VOX player, as are the Reich/Pulse MQA tracks I ripped from the CD I purchased. Those Reich tracks do produce the correct light on my DAC, but these iTunes tracks do not. In summary, Apple is presenting the new "Radka Toneff - Fairytales - Original Master Edition (MQA)" album in the iTunes store exactly the same as reviewed by major audio magazines and exactly as sold at the usual high-res download sites, albeit the iTunes version does not appear to actually be MQA'd. That presentation seems wrong to me, however the iTunes "MQA" files are of higher resolution than any other iTunes files I'm aware of, and they sound very good - audiophile quality or very nearly so.
  19. This recent model from Focal was supposed to replace the Focal Spirit Pro as far as I know. Physically I'd agree - the Listen Pro is much nicer in that respect, but sonically no.... http://www.hifiheadphones.co.uk/community/threads/focal-listen-pro-stereo-headphone-review.4523/

    MQA (Master Quality Authenticated) - Better Sound or DRM?

    And now for the thorough test with the Macbook, Meridian Explorer-2 (full decoder and renderer) and the generic non-MQA Vox player. This was a real headbanger since the DAC didn't always reset the lights reliably when changing the MIDI settings, but after a number of restarts I believe I have a replicateable test result. High-res 24/96 from HDTracks lit the lights as follows (Vox says 24/96): MIDI == 44.1: One white light. MIDI == 48.0: One white light. MIDI == 88.2: Two white lights. MIDI == 96.0: Two white lights. High-res MQA ("Studio") lit the lights as follows (Vox says 24/48): MIDI == 44.1: One white light. MIDI == 48.0: One blue and one white light. MIDI == 88.2: Two white lights. MIDI == 96.0: Two white lights. MQA from CD lit the lights as follows (Vox says 16/44): MIDI == 44.1: One green and one white light. MIDI == 48.0: One white light. MIDI == 88.2: Two white lights. MIDI == 96.0: Two white lights. MP3s (converted from non-MQA high-res files, or MQA files; Vox says MP3): MIDI == 44.1: One white light. MIDI == 48.0: One white light. MIDI == 88.2: Two white lights. MIDI == 96.0: Two white lights. So the MQA indications I got were: Green plus white (two lights == high res) on the "unsigned" MQA from a CD, with MIDI set to 44.1 Blue plus white (two lights == high res) on the "signed" or "Studio" MQA, with MIDI set to 48.0 The DAC seems to treat everything else as low (one light) or high-res (two lights) regardless of file format, but according to the MIDI setting. Which is why I asked in several places whether an MQA music player can force the MIDI to the correct values, in order to get a reliable indication on the lights. If these tests don't work out for other DACs or music players or operating systems or whatnot, I would not be surprised.

    MQA (Master Quality Authenticated) - Better Sound or DRM?

    Today I collected my MQA research into a small PDF file at the link below. Summarizing, I didn't find any negative issues in careful comparisons of two albums, in PCM and MQA'd masterings. Should there be an example of alleged sonic degradation in an MQA mastering, I'd like to download the PCM and MQA'd files from the usual high-res sites and compare them myself. Suggestions are welcome, especially when they point out particularly egregious differences. http://dalethorn.com/Audio_MQA_Notes.pdf
  22. Updated - see next post.
  23. Here's a video (audio only) that I made of the HomePod in the Apple store. It opens as I'm recording with cupped hands behind the earpiece mics, to screen out some of the customer/store noise, then I back off from there and remove the earphones from my ears so the sound is no longer binaural (i.e. the soundstage collapses). Unfortunately because of the store's background noise, I had to be closer to the speaker than what I would have liked, and thus much of the power and projection of the speaker's sound isn't captured well here. https://www.youtube.com/watch?v=OuOYdtW3sJ0
  24. I finally got caught up this evening on my backlog of reviews, so I ripped Disc 1 of my Silverman/Mozart Sonatas by IsoMike on SACD. I ripped the CD layer only, and converted the 16/44 WAV tracks to FLAC using Foobar2000 and the FLAC v1.3.1 codec. The compression was to 36.5 percent of the WAV size, i.e. the totals: WAV: 697115244 bytes FLAC: 254379988 bytes Since this is essentially the same type/technique/content density as the Silverman/Chopin IsoMike DSDs, and since the IsoMike folks made this SACD and its CD layer using the correct conversion software, it's clear that the compression to 23 percent that I got from the JRiver-produced WAV files is very short on 16/44 content.
  25. You get two things with the AMBEO - each worth at least $300 USD (IMHO): A very decent IEM, and a really good binaural recording system (using your Apple i-device) with microphones that capture hi-fi sound. This review has only a few sentences about the binaural recording - the bulk of the review concerns the IEM/earphones. http://www.hifiheadphones.co.uk/community/threads/sennheiser-apogee-ambeo-iem-earphone-binaural-recording-rig.4519/
