    modulo bluetooth per KZ
    Questo modulo rende wireless le cuffiette in-ear KZ (non incluse), questo è la variante con connettore ad "angolo", adatta solo a certi modelli come le ZS10 (in foto), attenzione che il connettore è diverso per questo ci sono 2 varianti (angolo e dritto).

    Cosa mi piace:
    è dotato di un'anima in metallo modellabile nella parte finale per adattarsi al proprio orecchio, devo dire comoda e più malleabile rispetto a quella del cavo originale.
    La batteria al litio da 60mAh è nella norma, dura circa 3 ore e si carica in 1 ora ma non è il massimo (forse è anche un po esausta), tutto sommato va bene per le dimensioni ridotte del

    contenitore ma fosse stato appena più grande per ospitare una batteria maggiorata non sarebbe stato un problema, vista poi l'alta qualità delle cuffiette che vanno abbinate.
    E' dotato di 3 tasti, avanti indietro e play/accensione/spegnimento, poi programmabili dal player per diverse funzioni. Ricarica tramite la classica porta micro-usb e cavetto incluso.

    Cosa non mi piace:
    l'unica cosa negativa è la scarsa portata del bluetooth, a volte basta voltarsi o abbassarsi nella stessa stanza e si interrompe l'audio, altre cuffiette BT economiche possono stare a 3-4 metri dietro un muro per continuare a funzionare.
    Quindi l'unico utilizzo possibile è avendo lo smartphone addosso o molto vicino, in questo caso l'audio è sempre stabile e di ottima qualità; immagino che una portata maggiore avrebbe influito sulla durata della batteria e quindi sulla portabilità, questo è l'unico compromesso da accettare perché comunque è un ottimo accessorio per completare il prodotto KZ.

    Quasi perfetto
    Confezione ben curata come ogni prodotto KZ Acoustics. Utilizzo il modulo per le mie camminate/corse, in accoppiata a delle ZSR. Audio buono anche se non c'è il supporto al protocollo AptX, ricezione buona fino a qualche metro dallo smartphone (quindi nessuna perdita di segnale col telefono in tasca) , possibilità di gestire chiamate e riproduzione musicale con i tasti e, come chicca finale che non mi aspettavo, c'è un feedback audio (per fortuna in inglese e non cinese) che avvisa quando il modulo è acceso/spento/scarico/chiamata in arrivo !!
    Insomma ad un prezzo cosi basso si possono connettere auricolari di qualità come i KZ, senza rinunciare troppo alla qualità e alla dinamica del suono ottenibile via cavo.
    La durata della batteria rispetta le specifiche, senza infamia e senza lode.

    Difetti (se proprio vogliamo trovarne):
    -il cavo è un pò viziato e rigido e non si adagia alla perfezione dietro la nuca (magari lasciandolo fuori la scatola perde un pò di "viziatura")
    -il cavo, sempre a causa della sua rigidezza, trasmette qualche rumore quando tocca agli indumenti durante il movimento

    KZ Bluetooth Adapter for KZ ZST, ES3, ZSR, ZS10 and ES4 fitment
    Hi, this is just a quick overview. This version of the adapter is the angled connector for the ZST,ES3,ZSR,ZS10 and ES4. My version is the bluetooth 4.2 and the verbal commands on the adapter are in English and Chinese and is really easy to pair to any bluetooth compatible device. For the low price I can't really fault the sound quality. The range I have found when used with my Sony Xperia Z5 which is also bluetooth 4.2 is over 15 feet away so has great range but your device may differ to mine so your mileage may vary. Battery life is a maximum of 4 hours.

    To pair to a bluetooth device just hold the play/pause button down for around 5 seconds to put it into pair mode and it will be called KZ Adapter.

    Included in the box is a very basic and short USB cable and instructions in English and Chinese.
    No real cons really for the price but it would be great to see a revised version with longer battery life and maybe Aptx. Also the included USB charge cable is too short.

    Greate sound
    Como este earbud é ótimo, sim, fiquei muito impressionado com a qualidade visto o preço que paguei. Sons bem definidos e cristalinos, é possível ouvir com clareza qualquer instrumento ou voz de uma música. Os graves são bem definidos mas tem menos peso do que outros fones que já usei. No uso são muito confortáveis, mesmo sendo maior do que de costume, após um minuto de uso não se percebe que eles estão no ouvido.
    A experiência de compra foi a melhor possível.

    In english
    As this earbud is great, yes, I was very impressed with the quality given the price I paid. Well defined and clear sounds, you can clearly hear any instrument or voice of a song. The bass is well laid out but has less weight than other headphones I've used. In use they are very comfortable, even being larger than usual, after a minute of use one does not notice that they are in the ear.
    The shopping experience was the best possible.

    unforgivably flawed
    Construction and interface are great. Verbal cue when you connect/disconnect from a device. Signal quality is acceptable.

    The problem is that unless you're holding the transmitting device within 12" (30 centimeters) or so, the signal will be intermittently lost resulting in an effectively unusable headset. battery charge has no impact, neither does the nature of the transmitter as I've tried this with 3 phones and 2 USB adapters plus a laptop with an integrated adapter.

    I have consequently ordered the updated version of the adapter in the hope that its performance is more reliable. Were it not for the connection issues this would be an ideal adapter particularly given the price.

FAQ for KZ Bluetooth Module Upgrade Wire for ES3 / ZST

  • Is KZ Wireless Bluetooth Module compatible with KZ earphones?

    It supports all the pluggable KZ earphones.
  • Does this module have mic to answer phone calls?

    Yes, it does.
  • Is there any lag(e.g 1second) when you watching films or playing games?

    Bluetooth devices will have a certain delay, about 0.1-0.5 seconds.
  • How do you change to Chinese voice prompts, and return back to English, or vice versa?

    In the power-on state, press and hold the volume + and play button at the same time to switch between Chinese and English voice prompts.
  • Snapping, crackling, popping, or no audio on one side, what can i do?

    1. Make sure the 3.5 mm audio jack is fully plugged in. The straight input connects to your headset, and the L-shaped input connects to your audio device.

    2. Check that your audio source is on and working.

    3. If your audio source is a computer or laptop, try adjusting the configuration settings.

    4. If you still hear distorted sound, try a different audio source and an alternate cable.

  • Phone not responding to button presses?

    Make sure that the headset plug is securely connected. For multi-press functions, vary the speed of presses when you use the remote / mic.
  • Microphone does not pick up sound, what is wrong?

    1. Make sure that the headset plug is securely connected and that the socket is clean and clear.

    2. Check that the microphone—located on the back of the remote—isn't blocked or covered.

    3. Make sure the straight-end of the plug is connected to the headphones and the angled L-shaped plug is connected to the audio source.
