Vanzon Bluetooth Speakers, V40 Wireless Portable Bluetooth Speaker with TWS Dual Pairing, 24W Stereo Sound and 24H Playtime, IPX7 Waterproof Bluetooth Speaker for Home and Outdoor by Vanzon

Awesome Speaker with a AWESOME Light Feature!

I bought this speaker for entertaining and it has exceeded my expectations. The sound is crystal clear with deep bass, and the 24W stereo output really fills the space. The waterproofing is a huge plus. I’ve used it in the shower with no issues.

My favorite feature is the built-in lights on the sides. It adds such a fun and vibrant vibe,. Whether you’re having a backyard gathering or just relaxing at home, the light adds a “light show” to the music that sets the mood perfectly. It turns any playlist into a party. It also could be set to the more slower paced color changing mode (breathing mode).

The 24-hour battery life, Bluetooth connection, and compact design complete this perfect portable speaker. Highly recommend! Great Gift!!

Great little speaker! Super portable, easy to pair, and the sound is much louder and clearer than I expected. Battery life is excellent, and it’s perfect for travel or outdoor use. Definitely worth it!

Many of the differing opinions posted here for these speakers, and even my review, are influenced by how many BT speakers we have actual experience with. I have a big old BT speakers, old as in 2014 😉 Its battery life is fading. Its size & mass probably help it produce its good bass. Since it’s that old, it lacks the benefit of newer BT technologies; it connects slowly and it’s too agressive at disconnecting, presumably to save energy.

Compared to that big old thing, my pair new X5 Pro BT-5 speakers seem great. They’re smaller, lighter, and sound great. Being able to space them apart for wider stereo effect is REALLY really nice too. At the price I paid (a little below current price), getting two was not very expensive. BTW, I think any TWS pair should have the same benefit of wider stereo separation (duh). People have different tastes in volume and bass. For me, these are plenty loud and have good bass, with great sound quality, especially if I can use an equalizer to increase the bass sent to them. They can’t compete with my car or home stereo systems, but I never expected them to. They are for convenience for me. Pairing them together then pairing with my BT-5 phone works well, as I expect.

I’ve been frustrated by how two sets of BT features are very often mentioned but poorly explained, CODECs and PHYsical Layers (PHYs). I wish we could share URLs here; I’d point to some articles on the subjects. The problem is how your devices will NOT make use of good new CODECs, and how your devices will NOT makes best use of the newest PHYs, if at all.

Digressing briefly, it’s interesting to note is how long it takes new BT specs to reach market share. BT-5 spec was established circa 2017.

CODECs: By default, and most commonly used, is a CODEC called SBC, which BT requires in all BT versions. It doesn’t matter if your audio source is FLAC, OPUS, AAC, or MP-3 (I think Spotify uses Vorbis!). BT will (almost always) decompress the audio stream and recompress it in the inferior SBC CODEC, before transmitting to the receiving device. Many of you can appreciate decompression/recompression with lossy formats will result in decreased quality. It’s analogous to making a photocopy of photocopy of a photocopy. Detail is lost each time. You’ll see references to yet other CODECs, used mostly I think for BT, being available in some devices, CODECS like aptX, aptX HD, LDAC, and even AAC. These other CODECs are to varying degrees better than SBC. But unless both the transmitting device and its software and the recieving device and its software will make use of the same BT related CODECs, they’ll default to using SBC. Which is almost always the case. In theory an Apple AAC user could transmit BT without conversion to an AAC capable devive. Heck, in theory, any of those superior audio source formats (except maybe FLAC) COULD be sent without conversion if the BT receiving device supported the CODEC. Apparently none are so equipped. I’ll let the reader reflect on why that might be 😉

PHYs: Without delving into what a PHY is, just think of PHYs as hardware features that can potentially provided enhanced performance. BT-4 introduced low energy (LE) with a good 1 mbit/sec data, made possible by what is called PHY LE 1M. BT-5 adds among other things, two more PHYs, LE 2M (doubles the data rate potentially for better audio quality) and LE Coded (quadruples the range, potentially).

But implementing PHY LE 2M and PHY Coded are OPTIONAL. So a manufacturer can make a few enhancement required by the BT-5 spec, but essentially sell a BT-4 device as BT-5.

And like with the CODECs, the devices may not support the same PHYs, thus preventing their benefit.

Very few phones support all the PHYs yet. Most support either PHY LE 2M or PHY LE Coded, or neither. I have read of very few supporting BOTH yet. And those that do are both cheap and expensive models, so it’s not obviously a cost issue.

For Android owners, there’s an app called nRF Connect for Mobile that can be used to identify which of these PHYs your BT transmitting device (phone, tablet, etc.) supports. My phone doesn’t support PHY LE Coded. It does support PHY LE 2M (high speed). As required for all BT-5 devices, my phone DOES support BT low energy (BLE), but that’s not a PHY by itself. I’m not sure, but I think all BT-5 devices must support PHY LE 1M. BT-4 with PHY LE 1M is actually pretty good, including distance/range.

Speakers and earbuds and headphones support various PHYs, without telling you which if either of the two new BT-5 PHYs they support. I have yet to see a speaker description identify which PHY it implements. But there are hints. If the description mentions extra long distance connectivity, then there’s a good chance it uses PHY LE Coded (long range).

I wanted BT-5 for enhanced connections and the possibility of the benefitting from the better CODECs and PHYs. I cannot (yet) tell what these speakers support. While, as stated above, I was able to use nRF Connect for Mobile to determine my phone’s features, I could not figure out how to use it to tell me about these Vanzon X5 Pro speakers.

I wonder what the speaker manufacturers use to accomplish this speaker-to-speaker TWS connecting. But again, I digress.

I just know my X5 Pros sound great in TWS mode, very good standalone, they connect fast, and (so far) have good battery life. I’m very happy with them. Other than specs, it’s hard to know for sure how well they really compare to other similar speakers. People’s opinions are so subjective and sometimes biased, it’s hard to rely much on reviews.

Ne peut être utiliser l’or de la charge et ne peut être chargé tant que la batterie n’est pas complètement déchargé..

This bluetooth speaker is compact and has good sound quality. It is also waterproof. I am going to use it to go to the beach in the summer and not have to worry about sand/water. It also has an SD card slot and takes up to 64 GB cards. It says that you can connect two of these to make a better stereo experience. I might have to get another one and try that out. Battery life is good. I have had it playing for 8 hours a day for the past few days and it hasn’t had to be charged yet. The only downside is the LED flashing lighting mode isn’t maintained after you power it off. You have to change the LED setting each time you power it on. Not a major issue though.
