Review: Small yet powerful portable dac/amp with PEQ - To my knowledge this is the first ultra-portable dac/amp with 10-band PEQ, which is the key feature which made me pick this over its competition. It easily powers my relatively hard to drive Hifiman Sundara headphones even with the 3.5mm single-ended (unbalanced) output, and gives me great EQ options when streaming from my phone as well. Can be used as a USB DAC/AMP both with your phone or PC, and wirelessly over Bluetooth with LDAC and other codecs. The app is good and opens up many options and settings not often seen on similar devices. Their general forum and Customer support is quick, engaging, and responsive.
Review: 普段はsony 1000xm4を使っています。今回使ってなかったse535 LtdをBluetooth化する為に他のワイヤレス機器を色々みましたが値段が高くこちらがコスパが良く購入しました。 普段レビューしないですが他の方の参考になればと思います。 実際に使ってみて大変満足です！ 元々高音よりで女性アーティストの曲が好きでse535Ltdを使っていましたがワイヤレスのイヤホンの方が楽で出番がなかったのですがワイヤレスとして復活ししかもアプリでイコライザーもいじれるので最高です！ USBで繋げて聞く事も可能ですがスマホとの相性が悪いのか音が篭って聞こえる為ワイヤレスのみで利用する予定です。(Xiaomi 11t) 今回こちらの購入と合わせてバランス接続する為リケーブル(BIGMANGO-crystal)しましたが素人なので余り違いが分かりませんが気持ち全体的に音が分離してさらに聞きやすくなった感じがします。 後はエージングしてどうなるかが楽しみです！

## Questions & Answers

**Q: Does computer supply power thru usb when it works as dac or it work on battery power?**
A: Yes, 5K USB DAC gets the power source directly from USB VBUS.
It won't drain any battery power when working as a USB DAC. (Unlike BTR5...)

**Q: Can i get full benefit of apple music lossless tracks on iphone 12?**
A: Yes, as long as you use this as a wired connection and with headphones that can reasonably play 16bit/44.1hz quality. Things to keep in mind: 1) The headphone is as good as the DAC, and vice versa. 2) Bluetooth is never really "lossless," but you can get approximates that are likely to fool your ears and thus be the same thing. Using the Qudelix as a bluetooth DAC will not give you "lossless" music output, but it will be very, very good. If you want true "lossless," you have to be wired. 3) On Apple devices, be sure to enable lossless output in Settings for iPad/iOS, or Music preferences AND in the MIDI launcher on Mac. Happy listening!

**Q: How can I pair this divice to a wireless earphones?**
A: It is not made FOR bluetooth earphones—IT IS A BLUETOOTH device itself!  Just plug in wired earphones & they ARE NOW Wireless Earphones when Quedlix 5 is paired with an audio source!

**Q: Is it possible to connect this to a pc via usb, then have the dac stream music to a bt headphone?**
A: Only if the BT headphone can be connected with a cable to the headphones.  Some BT headphones have a jack for a wired connection.

### ⭐⭐⭐⭐⭐ Review
*by お***こ on May 1, 2021*

Nintendo Switch のドックに USB 接続して使える DAC をこれまでいろいろ探して試してきましたが，音質的にはこのDACがベストです．この DAC は基本的に専用のスマホ用アプリ経由で設定するのですが，USB DAC の設定を 16-BIT Mode にして周波数を48 KHz に設定するだけで使えます． Nintendo Switch で使える DAC 選びはまず USB Audio Class 1.0 に対応するものを探すところから始まるのですが，認識して音は出ても音ズレが発生してゲーミング用途には使えなかったりするモデルもあります（たとえば Astell&Kern の AK70MK2 は Switch で認識して音はでますが，音ズレが大きくゲーミングには使えません）． 本機は音ズレ（レイテンシー）も極小で，Switchのスプラトゥーン2という音づれがシビアなシューティング系のゲームでも違和感なく快適にプレーできます（とはいえ，Switch本体のステレオミニジャックの音と全く同じタイミングで音が出るわけではなく，数十msecのずれはあります）．ゲーム音質的にもこのサイズと値段からは想像できない1クラス上のパフォーマンスで自信を持っておすすめできます．音質も満足なのですが，音量を非常に細やかに 0.5db 単位で加減できる点もグッドで，インピーダンスが高めのヘッドフォンもドライブしてくれます．
