As described, which is a good thing
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.

Bluetooth connectivity even at a distance
Wanted a second speaker to listen to audiobooks while sewing in an upstairs room. The Vanzon set-up is pretty easy, it discovers bluetooth devices with just a short delay, then emits a tone so you know it’s connected. I can set up my audio book in the kitchen and carry the speaker upstairs and it doesn’t disconnect or get distorted. Nice size. Good sound quality without distortion at the loudest setting. Seems to stay charged pretty well, although drains faster if using bluetooth at a distance for a long time. It was priced competitively compared to other similar speakers. It can be linked to another speaker but I haven’t tried this. Comes with a type-C charging cable.Negatives: Not as loud as my old speaker, so it does not work well with my loud sewing machine unless I have it positioned right next to me. There is no visual display of the mode in which it is operating. the charging is included, but is a type c. As I have all android devices, not apple, this is the only type c device I own so when it needs to be charged I have to figure out where I left the cable or just keep it connected to the speaker at all times.

Thank you quick delivery great product

Built quite tough. No issues connecting. Sound quality is good.

Thiught it was good but wife said ibwas ripped off and am a fool. I dont no which us right. But she said she knows best so I trust her .
