    Does the Bluetooth receiver made by professional HiFi manufacturer differ from that of Internet company like Xiaomi?
    --- Translated from James’ Original Post

    Firstly, let’s have a look at the comparison chart!
    1.png

    It’s known to us all that the cost performance is the key value the Internet companies advertise and promote. To me, it makes sense in most cases. However, Internet enterprises are likely to save cost on things that customers may neglect.
    Therefore, I take the newly-released Bluetooth receiver of FiiO to make a detailed comparison with the counterparts of Internet enterprises like Xiaomi / NetEase, so as to analyze how the two different kinds of enterprises think differently in making products.

    1. Market positioning
    Form the product positioning aspect, the target customer group for the 3 products are the same as the prices are quite close.

    2. Core needs of target customers
    From the promoting points of the products and customer feedback, the device is to meet the needs of customers whose phone comes without the 3.5mm headphone jack while still have one or more 3.5mm headphones with pretty satisfactory sound quality. Sure there are some users may buy the device for other reasons.

    3. Sound quality
    It’s a pity that the Bluetooth receivers of Xiaomi and NetEase don’t support aptX. To most of the users, the sound quality of aptX transmission can nearly rival the wired connection. As a phone manufacturer, Xiaomi is supposed to provide a reasonable solution to users with 3.5mm jack removed from the phone. At the same time, I understand it’s for cost consideration. In order to make aptX transmission possible, the only way at present is to use the Bluetooth receiver chip made by Qualcomm which requires to pay the extra aptX patent fee. So if just go with the domesic made chip, it can save a lot on the cost.

    4. Features
    The Bluetooth receivers of Xiaomi and NetEase come without independent volume control and microphone, which means, if the user wants to use these functions, a set of headphones with in-line controls and microphone is also needed. While the independent volume control and built-in high sensitivity omnidirectional microphone allow the user to use it with ease no matter the headphones has with in-line controls and microphone or not.
    Indeed, the removal of the volume control buttons and microphone can save some costs, but it would definitely bring inconvenience to the customers. If you are in the mind to get a Bluetooth receiver, do think it over your needs and what kind of headphones you will pair with so as to avoid any inconvenience in future use.

    5. User-friendliness
    From the conventional view, the biggest difference between Internet company like Xiaomi and manufacturing company like FiiO is that Internet company is often associated with big data. With big data, it’s supposed to know better of the consumer needs so as to bring out better products to the public.
    However, as I can see that the fact is on the opposite. Take Xiaomi for example, they make phones with Type C port and NFC function, while strangely, their own Bluetooth receiver adopts micro USB port and doesn’t support NFC function. So, to be honest, these costs shouldn’t be saved. In addition, the FiiO μBTR takes just 1 hour to achieve a full charge, which is faster than that of Xiaomi and NetEase.

    6. Battery life
    As a portable product, battery life is a very important indicator. When I was still working for OPPO, the president of OPPO had once said to us that a portable device should have at least 8 hours battery life so as to ensure a full day use outside. Therefore, the μBTR is of no exception offering 9 hours battery life which may probably last for 10 hours for proper use. While the other two products can only last for 4 hours which is not so convenient at all in actual use.
    As the saying goes, you get what you pay. All in all, wish you get the great sound quality out of your device and have a nice experience.

    curious to see how this compares to the RC-BT, BTR1, and the soon to be released BTR3

    Didn't realize there's a dedicated uBTR thread. Cross posting it here.

    I bought a uBTR from Amazon and received it today. Paired with an iPhone 8 I can confirm it does connect via AAC.
    Code:
    Starting a2dp send thread, handle 1, frameLen 743, framecount 1, codec 2, bt clk
    RF is fine, I can put my phone in a room 30 feet away and the music still plays. That's what I expected since even my cheap Anker bluetooth headphones can do that, but I've read complaints about the BTR1 cutting out so maybe the uBTR does better. The body is made of plastic so that might be a factor of better RF performance.

    Sound quality wise it's not bad. I did a quick comparison test with the Apple dongle and the dongle definitely sounds better. There's a loss of detail when using the uBTR in comparison.

    Noise floor was pretty low. I didn't hear any hissing using my old q-JAYS with Shure black olives.

    EDIT: Some additional details from the FCC filings of the uBTR.

    So expect a similar design for the uBTR5. No surprises there since they've shared the pictures already.

    On RF performance:
    uBTR Output watts: 0.001172

    BTR1 Output watts: 0.0009

    What do we know about the uBTR5?

    And what about the "soon to be released BTR3" mentioned a post earlier?

    Thanks for any info.

    How do you switch between two paired devices using the main button? I don't see it in the manual.
     
  10. FiiO
    Dear friend,

    Do you switching using the button in μBTR? It is not a supported function for the μBTR. The BTR3 will have this feature instead!

    Best regards

    The features list says it can be paired with two devices. The images in the first post also say the main button is used to switch between devices. How does this work? Does it stay connected to two devices simultaneously like the Bose QC35 and it automatically switches to which every device starts playing audio last?
     
  12. fyleow
    I have mine paired to both my MBP and iPhone, and it will switch to whichever device is playing audio. I tested it briefly with a Youtube video playing on my MBP and the stock Music app on my iPhone. I don't use it day to day so I don't know how well it works or what happens when system sounds play on the MBP while you have music playing on the iPhone.

    Dear friend,

    Not sure whether you are misunderstanding.

    After connecting to deivce A and device B , if you play music on device A, you can hear the music from it on the μBTR. And if you pause the music on the device A then play on device B, you can hear the music from the device B.

    Best regards
