Initial setup was ok. Synch up with my Zoook Bluetooth took a bit of trials post that it was a pleasure. The Philips Bluetooth headset volume was very low..so the latest version of the Bluetooth headset gives a better voice quality and volume.I connected the unit to Hathway cable TV modem audio ports. This gave a zero lag experience and it's a pleasure to watch your program without disturbing your family. Buy this unit if you want to use digital audio ports. If it's for analog signal there are other better economical alternative. Or you need more distance between the unit and your self.Tried the distance coverage..it works fairly ok when there are no obstruction wall.. typical Bluetooth issues affects the performance. ### ⭐⭐⭐⭐⭐ Reliable Brand. *by S***O on Reviewed in India on 4 February 2019* I have purchased multiple Cubetek Products in the Past. I have never been disappointed. In fact I am amazed by their Reliability, functioning precisely as described in the Product Description. I recommend Cubetek Products to my Friends without reservation.In addition, the Versatality and Utility of this Product is commendable. Output Volume is indeed quite low, but it is not a Deal-breaker.If there is a Cubetek Product meeting any of your needs, go for it without any hesitation. In fact, first Check whether Cubetek has a Product for your need, and then only look at other Brands.Many Reviewers have mentioned about the Seller’s (Melodymedia) Customer friendliness, which I never got to check up, as I have never needed it. ### ⭐⭐⭐⭐ Doesn't work with Dolby / 4K signals *by K***L on Reviewed in India on 23 August 2019* Works well with HD signals.Easy to setup. Build quality is great. Feels very sturdy. Comes with all required cables. Only bummer is that it cannot process 4K or Dolby signals. I had to return the product because of that. Tata Sky HD or other DTH boxes should work fine. A good product overall.Doesn't work at all with 4K / Dolby Signals.EDIT: MelodyMedia is very professional and reliable seller. My return process was very smooth and the seller seemed genuinely interested in understanding my problem and finding a solution. The return process was smooth and I got the money back in a couple of days. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/83776250-cubetek-bluetooth-transmitter-v4-2-50m-long-range-aptx-ll](https://www.desertcart.co.uk/products/83776250-cubetek-bluetooth-transmitter-v4-2-50m-long-range-aptx-ll) --- *Product available on Desertcart Great Britain* *Store origin: GB* *Last updated: 2026-04-22*
