FiiO D03K Coaxial/Optical to Stereo Audio Converter (Black)

I had LG 32” TV until few months back and connecting through 3.5 mm audio output of TV, I was using Sennheiser RS110 wireless audio transmitter with headphone. I enjoyed listening to music and movies and other programs after my wife goes to bed at night. I was fully satisfied with this arrangement as the music can be heard BOTH in TV speaker and my Sennheiser headphone when my wife also watches TV, with independent control of volume level.Last month bought SONY 43W800D SMART TV expecting that I can continue to enjoy the above facility. Unfortunately to my disappointment, SONY has only optical output and no independent 3.5 inch audio output. After searching SONY and other websites, I found out that present generation SMART TVs do not provide audio output. I don’t understand why advancing technology should mean cutting down old features and facilities. (I will be happy to hear from other people who have knowledge about why this feature is removed in SMART TV).As I am having hearing deficiency as a senior citizen with TV speaker sound, I was longing to get solution like my previous LG setup. Some reviewers in amazon.in were sceptical that if optical output is connected to this DAC, main TV speaker volume will be cut off. One reviewer in amazon.com however, had exactly like my requirement of sound in BOTH headphone and TV speaker. He said this DAC converter is good solution. So, straightaway I ordered this.I connected as per instruction and to my surprise, the sound from the headphone is better than my earlier LG setup, maybe because this is from optical output which is of superior quality than analogue 3.5 mm audio output of my earlier LG TV.I recommend to people who have need like me to go ahead and use this device. Except that it is expensive (this FiiO DAC is almost twice the price of other DACs) it is totally satisfactory.

I recently bought the DAC along with a Blue Rigger Toslink cable to to connect my LG 34600 LED TV to my speaker system to my speaker system, It is very very good,Sound Output is excellent,when connected to SetTop box, Laptop or DVD playerClarity is good too, no need to use equalizerfor TV setting use PCM out and the sound automatically comes out of the Optical outThe only downside is the absence of a volume control on the deviceIts best to connect an external device which has a chromecast and control levelsPrice wise is expensiveHappy with its performanceI recently found that the sound output is less compared to when it was installed,product working fine

After using this product (almost daily) for the last 6 months, this is without a doubt - an excellent stereo DAC.As the description and product photos mention, this device can connect unidirectionally from:1. Digital In - Either Optical or Coaxial cable on one end to2. Analog Out - Both Standard 3.5mm (headphones or old 2.1 audio systems) and AV audio on the other end.The old speakers of my 2.1 Audio system could only connect via 3.5mm jack -- because the 3.5mm Output port was not present on the LED TV. Since the LED TV had Optical Audio Out, I interconnected a Digital Optical Audio cable (purchased separately) from the TV end with the 3.5mm jack (from Audio system) using this product and confirmed that the switch on the DAC is set to 'Optical input' in my case.After connecting the DAC, it needed a couple of minor confirmations on TV Software side (actual process differs based on TV manufacturer hence only describing generic steps below):1. Confirm Digital Audio Out in your TV's Sound Settings is set to either: Auto or PCM as this DAC supports PCM only.2. Switch on both TV and Audio system, play any random audio and listen for any lag/echo between the two systems. You may need to manually adjust PCM delay until both sounds seem to merge.After confirming above settings on the TV software side, the resulting audio sounded flawless from both the TV and speakers simultaneously. Audio was perfectly in sync between both systems.Since no power adapter is provided (only USB cable provided), any basic 1Amp power adapter can work. Luckily, the DAC can even be powered by the TV itself (just confirm if TV USB Connection is 1Amp; anything less may lead to static noise heard in audio system)Delivery was prompt (as per scheduled date), packaging was perfectly done and build quality is top-notch. After an initial setup requiring 5 mins, I've almost forgotten about the mini-DAC in the ensuing months.

Over all sound quality is good and works as described. But to get good sound output source sound signal has to be strong. If it is weak then sound output is very low. Manufacturer should have provided internal signal amplifier for better performance.
