Sonata BHD Pro Type C USB dongle DAC, USB C DAC,Headphone Amplifier 4.4mm& 3.5mm,PCM384kHz,DSD256,MQA8X,Tidal for iPhone&Android&MacOS&Win (Sonata BHD Pro-Grey)…

This little DAC/AMP combo provides more than enough power for my Sennheiser 6XX.Pros:No setup is required, just a simple plug-and-play with my Windows 10 PC, Samsung A54, and Samsung Tab S7 Plus (I assume it would work for all Android devices as well).The sound is very clear and adds some warmth to all of my headphones.The casing is metal and the build quality seems great so farIt looks good and the clear window adds a touch of coolVery smallThere is one very small inconvenience. The volume buttons on the side are pretty much useless. Each press of a button changes the volume VERY little so changing the volume with those buttons is a small pain. When plugging it in for the first time, I recommend holding the Volume Up power button for a few seconds until it reaches max volume (or wherever you prefer), and then using the volume adjustment on your PC/phone to change the volume.I thought mine was defective at first because I didn't hear anything after I plugged it in, and pressing the volume up button didn't do anything. It took 2 or 3 seconds of holding the volume up button until I heard something.Overall great device. Highly recommend especially for the power and sound quality for the small size and very reasonable price.

For those on a budget looking to increase the sound quality of their music, this dongle does not disappoint. Combine it with CCA C12 IEM and you have an excellent combination. I have another, higher quality DAC dongle and the sound quality between the two is not highly noticeable. The reason I give it 4 stars are 2, no app to fine tune and all you get is an up/down volume button. But if you're looking to just upgrade your listening experience then this will do the job.

My second Sonata BHD Pro (for the road, the other for home use). The sound is incredible, separation and details are amazing, and the price for this is incredible. I have a number of USB DACs, including the Audioquest Dragonfly Cobalt, and this is just so much better, and under a quarter of the original price of the Cobalt. Recommended.

Update 2024-03-08:The volume has broken on my device. It seems the volume rocker is created by two buttons that are installed onto the main PCB, but I'm not even sure these buttons are soldered. I unscrewed the DAC and found that one button came off completely and cannot be put back. I checked the other button and there doesn't appear to be any soldering or anything else to hold it in place besides metal clips. I reached out to the manufacturer a week ago but haven't heard back. However, I'm not hopeful: a few months ago I reached out about firmware updates but never received a response.Such a bummer because this has been a permanent part of my portable music experience since receiving it back in October 2023. While the sound is great, the manufacturing and support quality leave a great deal to be desired. I'm still giving it 2 stars because of how well this performs when it's working properly. I will update this review if I hear from TempoTec.Original review:My source player is a Samsung Galaxy Note8 with USB Audio Player, and my headphones are Technics EAH-TZ700. First, the physical product: at first I thought the window was a screen but appears only to be for cosmetic purposes to show the electronics inside. The LED is helpful when playing music from different sources; each color represents the different frequency and/or other status. Otherwise, it’s a simple DAC that comes with a short USB-C cable and has both a 3.5 and 4 mm jack inputs.I tested this using Technics TZ700 headphones both with the stock 3.5 mm cable and a third-party 4.4 mm balanced cable. The DAC makes both sound wonderful. I’ve researched DACs before and read it’s one of the first upgrades to make to a sound system after having good source files/media and headphones; I now know why. I’ve listened to a broad range of music and I can tell major differences with some songs and minor with others. Having it loud doesn’t hurt my ears either; the DAC separates the instruments and voices so well. The volume rocker could be a bit taller; at times, I found myself finding it without trying to look. Otherwise, it works well and fits easily in my Pelican case with my IEMs.

I've been using Sennheiser HD-600 and the BHD Pro with a Win11 laptop and Foobar2000. Playback of all my DSF and FLAC tracks has been flawless. The DSD Processor in Foobar works very well in combination with the TempoTec USB ASIO driver.There is plenty of usable volume for the HD600 using the 4.4mm jack and the audio quality is on par with my other standalone DAC's and amps.I am very happy with this device when using it in the way described above.

I have ordered 2 of these dongle dacs and both are defective. The single ended output works fine but the balanced output fails when turned up passed half way. The sound fades out and static takes over. The first one died shortly after this. I stopped using the second one before it died for fear it would damage my IEM's.

$70 dollars, this is amazing for $70 dollars, the size of your thumb (smaller thumb that is), equal to a mid level system. I bought it for Saturday mornings when I wanted to keep it quiet for those sleeping later. It’s so good, so simple.Worth much more than it’s present price. Honestly a fantastic value for right now, how’s it sound ? 10 times better than you would expect, nice clean top end, very decent mid, bass is a bit thick, but it adds to an intimate presentation that’s enjoyable for hours at a time. Great audio buy for 2023.

after hours of trying multiple things, devices and OTG adapters, I was frustrated that I couldn't get it to work on any android or IOS device.... then It dawned on me that the I was using the included cable and it is defective. found another usb c to usb c OTG and it works great. took a star for the inconvenience

普段、外で使っている Pioneer XDP-20(イコライザー : フラット、2.5㎜バランス)との比較です。再生環境スマホ　LG velvet(バッテリー4300mAh : Android 12)イヤホン　Moondrop 蘭 4.4㎜ バランスアプリ　ONKYO HF player (EQ Flat)音質はっきり・くっきりした音で、音の輪郭がよく分かりますが、少し音が硬い印象を受けました。低音もはっきりと聴こえるので、その分、量が増えた様に感じました。(多分、実際は増えてない。)また、音が少し硬いので、エレキギターを含む弦楽器や、シンバルの主張がやや強めです。ですが、全体としては、フラットの範疇に収まっていると思います。スマホ直刺しと比べると、明らかに音のざらつきが無くなるので、効果は十分にあると思います。音量も60段階の細かな調節が可能です。(60段階は、AliExpress の商品説明で、実際には60段あるか試してないけど、XDP-20並の細かな調節が可能です。)バッテリー消費について1時間の使用(FLAC 44.1kHz 192kアップサンプリング)で、8～10%位消費します。付属OGTケーブルについて細いですが、C端子にはカッチリ入り、外す時も結構、力がいるので、外でポケットからプラプラさせても外れた事は今のところ無いので、とりあえずは、これでよいと思います。総評スマホより細かくボリュームが調節できるのが、本当に便利で、素晴らしいです。多分、シーラス・ロジックのCS43131のDACチップをデュアルで搭載し、バランス接続対応、独立ボリューム搭載モデルとしては、一番安いと思います。また、メーカーのTempoTec は、ガチのDAPも作ってるので、信用出来ると思います。そういう意味でも良い商品だと思います。
